Ventx Ltd

We help clients to deal with their industrial noise problems via the development of special equipment. We design, manufacture and then install the most reliable silencers. To meet differing needs, we supply these products in different forms. They include the vent silencer as well as other useful models. Our merchandise can comfortably meet your specifications for very competitive prices.

Silencers, attenuators, sound traps, baffles, splitters, and mufflers are all similar. However, they are slightly different in how they work. You need to consider this to make sure you choose the right model for each application.

How they work and the impact

In general, such noise reduction contraptions minimise sound from inside an air intake system. It is the same for exhaust systems, vents, and more. These could be venting air, steam, or a gas. You need the best solutions here to address the noise and make sites safer.

Any mechanism capable of obstructing or altering the airstream will lead to a pressure drop. This will happen within the system, affecting the flow. As a result, any silencer will demand sufficient engineering. It is necessary to balance the noise reduction against the acceptable pressure drop inside the system.

Applications

There are a number of critical and extreme applications for silencers. They demand commensurately suitable extreme manufacturing and engineering solutions. Said applications can include any with high temperatures, mass flows, or velocities. Gas turbines, and airstream particulate are common examples.

This is also the case with blowdown and vent silencer products. These special noise reduction tools are inherently pressure vessels. Thus, you need to precisely manufacture and design them. They can’t endure extreme conditions otherwise.

You cannot overlook the quality and attention to detail for essential noise control components. This is because safety always has to be the leading consideration when designing for such extreme conditions.

Speak to us if you need a vent silencer or other models

An important thing here is we make use of advanced computer software to match all our silencers to the particular applications. It means our clients get products that will fit and offer the best performance.

So, if there is anything we can do for you, please let us know. We are sure we can deliver a vent silencer for any application, including extreme venting for safety reasons and more.

One of the major problems in the UK when it comes to property maintenance is too many people wait until there is an issue. It can make it harder and more costly to resolve them. Being proactive is much better. That is the case in every regard, whether it is checking the HVAC system, roofing, or even things like attenuators.

While spring has only just arrived, it is a good idea to make sure your HVAC system will be ready for summer. You likely won’t need it much this season, but it could become vital in the next one, especially for workplaces. It is a wise idea to prepare now and make sure it will be ready.

What to do?

There are a number of crucial things you should do here. Firstly, it is important to check air filters. If they are dirty or damaged, it can have a big impact on air quality, efficiency, energy bills, and noise. So, you may need to clean them or get replacements.

Secondly, you should check the condensate drain line. HVAC systems have the drains to remove moisture from the system. However, in time they can suffer from clogs. If that happens, it can lead to leaks and makes the system less efficient. It is a good idea to have a look and clean the line if necessary.

Thirdly, you should inspect parts of the HVAC system that are outside. Make sure there is nothing blocking the air intake.

Finally, you should check all of the vents and exhausts. You don’t want them to be dirty and clogged as it will hurt system performance. In the worst cases it will mean you are circulating dirty air and contaminants in the property. Have a look and clean them if you need to.

If you have attenuators, make sure you check and clean them too. That can also help performance and ensure you don’t have noise issues.

Tuneup

In some cases it may be best to contact a professional about your HVAC system. A technician can do a more thorough check to make sure everything is in order. If they spot issues, you can arrange repairs, replacements, or further cleaning. Ultimately, it can ensure your system is efficient, safe, and reliable.

Ask us about attenuators

At Ventx we know how crucial HVAC systems are. They can be essential for the health, safety, and comfort of people in all kinds of properties. However, there are also issues with energy efficiency, hygiene, and noise. The right kind of upkeep can help with a number of these problems. High quality silencers and other solutions can also tackle noise. We are happy to supply products to do the latter.

So, if you want attenuators or other solutions, please contact us. Our knowledge of acoustics, engineering, and noise control in different industries is vital to ensuring you get the best products.

A noisy work environment isn’t one you want to be in. Long term exposure can cause several complications. Even being around excessive noise for a short time isn’t healthy if the sounds are loud enough. By using our attenuator products though, you can keep the noise at reasonable levels. We make our goods using the highest quality materials and design them with care to maximise the performance.

At times, we can experience extremely loud sounds. Even if the exposure is only brief, it can cause harm to our inner ears. This can lead to noise-induced hearing loss (NIHL). There are various misconceptions surrounding this problem. Not everyone knows the facts. We do however, and we are going to share them with you here.

Everyday activities have no impact

Our first misconception is that everyday loud activities are unable to influence our hearing. This is definitely not the case. It is possible for NIHL to be caused by a plethora of sources. Examples include farm/lawn equipment, firearms, fireworks, sporting events, and concerts. These could be things you use every day without even realising the sound is loud enough to harm you.

Hearing loss does not affect the rest of your health

Another misconception is that hearing loss won’t affect the rest of your health. Untreated NIHL increases the danger of someone undergoing cognitive decline. It can also cause depression, social isolation, falls, balance disorders, dizziness, and dementia.

Moreover, hearing loss takes away our ability to remain aware of our surroundings. It can have a massive impact because people may not be able to recognise safety hazards. As a result, it can mean more risk of injury at work, in public, and even around the home.

It is immediately noticeable

The last misconception we will discuss is that NIHL is something you notice immediately. In truth, it is often the result of years of loud noise exposure. You may not see signs until you have a permanent ringing in your ears. In some cases it will take a co-worker, friend, or family member to point out common hearing loss signs. But, once the damage is done, you can’t reverse it.

What to do?

Comprehending noise hazards and safeguarding in a high-noise setting can help. Using the likes of attenuators and other silencer products will be vital if you work in a noisy industrial setting. You can also look for ear protectors you can use when you are going to noisy events like concerts. Plus, it is a good idea to choose quieter equipment like lawn mowers to use as part of your job and at home.

Do you want us to design an attenuator for you?

At Ventx, we’ve been working with silencers for over a decade. Our establishment has served the needs of the Services and Petro-Chem industries as well as many others. What we do here is conduct acoustic analysis to learn as much as we can about the noise, including the sources, paths, and other details. We then create a bespoke solution.

With the right attenuator by your side, you can keep noise levels under control. So, please contact us if you want our utensils.

The purpose of our silencers is to minimise the noise in industrial environments. Leaving things as they are here can cause a number of issues, with some being irreversible. As a result, it is necessary to take certain steps before it is too late. We help by installing intake silencer solutions and many others.

There are several types of silencers out there, including pneumatic ones. They restrict the noise of compressed air. However, there is a fair amount of confusion about the necessity. People also often struggle to understand what they do and what to look for when buying one. We want to have a closer look here.

Air and sound

Various machines use pressurised air as an extremely efficient energy transfer method. But, when they release it, we all know. The dB(A) can reach as high as 100. To compare, a jet engine is over 140dB(A). The noise isn’t linked to the size of the tube or nozzle. Instead, air velocity is critical. What this means is that changing your equipment sizes make virtually zero difference. Studies indicate that halving your nozzle area leads to a minor 3 dB(A) reduction in noise.

To word things differently, when you have compressed air, there is a lot of inevitable sound. The size of the equipment does not matter. You can use silencers to instigate a pressure drop, lowering the velocity of the air. Consequently, the decibels go down as well.

Do we need pneumatic silences in every system?

Next, we will discuss whether you need a silencer in every system. They are not essential for equipment productivity. Substandard products will actually contribute to downtime since they block airflows. So there can be cases where you don’t need them.

However, noise control is inscribed in multiple parts of UK legislation. Examples are The Environmental Noise Regulations 2010 and The Control of Noise at Work Regulations 2005. Failure to stick to codes of practice, guidelines, and regulations can lead to fines. There can also be possible hearing damage to people in the area. Examples do exist of successful court cases. These are ones brought against construction businesses that neglected to use pneumatic silencers.

For choosing the best silencer, the Health and Safety Executive provides guidance in certain areas. One of them is noise reduction. Here, you should target a reduction between 18dB(A) and 25dB(A). It can be greater though depending on the silencer.

Another area is flow rate. Your silencer should not minimise the designed flow rate. A decent product will preserve it, even if there is pollution in the system.

For construction, pneumatic silencers must also have enough strength to endure accidental impacts. This is vital as they can be used in very challenging environments with high risk.

Finally, there is maintenance. Silencers users can maintain with the lowest amount of effort are most important.

Do you need an intake silencer?

At Ventx, we have more than a decade of experience in industrial silencer design. We use our acoustic knowledge together with a deep understanding of quality manufacturing. This lets us produce stellar silencers.

We can provide you with intake silencer models and others to suit most needs. So, if you’d like to do business with us, please get in touch.

Industrial silencers are of great benefit to those who work within noisy environments. They help to prevent the physical damage loud sounds can cause. To get the best results though, you need to ensure you are using the right model. Our team supplies in-line silencer designs and various others. This way, we can match the differing needs of every client to bespoke equipment.

One fact about silencers is that they will likely be in use for long stretches of time. In fact, they can become more vital as systems age due to dirt and wear to components. So, maintenance is important. It could prove necessary to clean the exhaust port threads. Polluted exhaust air has the potential to meld with dust and dirt. Should this occur, it will fill the threads up with a thick paste. If you fail to cleanse them, your silencers can experience damage.

In this post, we want to discuss maintaining silencers in power facilities in more detail. The equipment is even more important here because the noises can be exceptionally loud.

Benefits

Silencers will benefit from a bit of external cleaning. You can also aim to clean pollutants existing deep inside your silencing materials. But, this will only work for the variants using large-pore membranes. They are the only ones that will experience improvements.

Use commercially available solvents

You are able to clean metal silencers by using whatever solvent is commercially available. However, certain silencers use porous plastics, like sintered polythene. It is not a good idea to clean them using solvents based on chlorinated hydrocarbons. The problem with these is that they can cause considerable damage to the silencer.

The cleaning process requires you to soak your contraption in the solvent. Do this for five minutes. Afterward, you must do a bit of scrubbing with a hard-bristle or nylon brush. It is not wise to use wire brushes here. The reason is that they can damage your silencers. When you finish brushing, use compressed air to blow your silencer clean.

Do you need a reliable in-line silencer?

At Ventx, we have supplied our silencers to an exhaustive list of clients. Each one has had machinery or systems that produce unacceptable noise levels. However, every client is unique in many ways, such as the layout of the property, what they use, and how they are using it. Thus, we need to provide different designs like our in-line silencer and others to provide the best result. This is why we only offer bespoke products.

So, if you find yourself in need of our merchandise, please give us a call. We are happy to suggest solutions for power facilities and any other noisy industry.

A huge array of different systems need valves for the control and regulation of pressure. It could be boilers, heat exchangers, autoclaves, or pneumatic tools. The idea is the valve can open when pressures exceed a specific level to allow it to drop back down. The issue here is it can create a lot of noise. However, an inline diffuser can help with it. Ventx can provide bespoke solutions to suit all needs.

Major noise problems

A lot of people don’t understand the severity of noise. However, it can be one of the biggest causes of ill health and environmental damage. A single noise over 125dB could irreversibly damage hearing. Regular exposure to sounds over 85dB can cause hearing loss too.

The noises can also have a massive impact on people in the neighbouring areas. Loud sounds can travel very long distances, especially if there are no barriers. It can cause disruption to sleep, relaxation, and more. The stress and strain can have a big impact on the health and wellbeing of locals.

Industrial noise pollution is also very harmful to the environment. It can disrupt wildlife in a number of ways. In some cases it can lead to a decline in populations because of disruptions to mating cycles and nesting.

Using an inline diffuser

With control and safety valves, the best thing to do is look at diffusers. They can go directly into the pipework after the valve. What they do is minimise the pressure drop to reduce the noise. They can do this without an impact on the flow capacity. The best designs share the pressure drop to optimise the process.

There are a number of benefits here. Most important is it can require minimal alteration of your system. The only challenge is generally insertion of the diffuser to ensure it is in the right place. Other than that it isn’t usually necessary to change anything else.

Using a diffuser can also save you from having to use acoustic cladding. Some people use it to clad the pipes to help dampen the noise. However, it can be costly, time consuming to install, and increase maintenance time. It is better to avoid it the diffusers alone will be enough.

Work with Ventx

We have built a reputation as one of the best industrial silencer experts in the UK. You can ask us to design and manufacture a range of solutions, whether it is an inline diffuser or another model. We ensure every product suits your needs, with the right hole sizing, spacing, and casing. The latter will comply with the necessary codes.

Many industries rely on vents to release steam and gases into the atmosphere. It is vital for a number of reasons, including reducing the pressure in various systems. Without the venting there would be a huge risk of system failure and even explosions. So, you will likely see a gas vent or series of them on most facilities.

There are a number of things to keep in mind with the vents though. For one, it can get noisy. The difference in pressure and a high flow speed can create loud noises every time you need to vent. With that in mind, it may be necessary to install a silencer. It will be a requirement if the noise is so loud that it could harm people or the environment.

The nature of vents also means you can have an issue with birds. This needs addressing as it could result in serious issues, high maintenance costs, and harm to the wildlife. We want to have a closer look at the problems here.

Why do birds like vents?

Birds look for safe, secure locations to nest. They tend to prefer places that are high up and far from potential predators. That can make a gas vent very attractive because of the location and height.

Vents often tend to be warm too. Again this is something a lot of birds look for, especially when they look for a location to nest and lay eggs. It can make a vent very appealing.

What are the issues?

It is dangerous to allow birds to nest in gas vents for a number of reasons. Firstly is the risk that they will clog up the pipe. If that happens, it can obstruct or completely restrict the venting. That can cause performance issues or serious system failure.

Secondly, birds can cause all kinds of issues because they bring pests and bad smells. That can cause lots of concerns with industrial operations. Contamination can be a major problem.

There is also the risk to the birds. Some will nest in a gas vent that doesn’t get a lot of use, such as emergency relief systems. If the system does need venting, it could kill the birds if the gas is exceptionally hot or high pressure.

Finally, there is the damage birds can cause to consider. Their presence can lead to more maintenance and repairs than you would expect. That can get costly and could even lead to additional shutdowns.

Talk to us if you need a solution for a gas vent

At Ventx we prioritise sound reduction to make industrial operations quieter. However, we can also factor in issues like birds. We can design silencers that include measures to stop them from accessing vents and pipes. It can provide long term protection from the problems they can cause.

So, if you want to find out more about how we can reduce noise from a gas vent and tackle bird problems, please contact us. We have a wealth of experience, ensuring we can support clients all over the UK in a variety of industries.

At Ventx we work to tackle the myriad of problems that industrial noise pollution causes. For example, we can help to make workplaces safer, protect the environment, and even improve industrial activities. The silencers we design and supply minimise the noises coming from various forms of machinery. They can also dampen sounds from vents, pipes, and more. Using the likes of our discharge silencer designs, and others, you can better manage the noise.

Noisy HVAC equipment

One recurring application of soundproofing technology is HVAC systems. Heating, ventilation and air conditioning solutions are vital in all properties. They ensure the spaces are safe to inhabit. However, they can release a lot of noise into our environments. It frequently surpasses the safe thresholds too. So, it is important to tackle it.

HVAC systems can get noisy for a number of reasons. Commonly the sound is due to the airflow and use of fans and motors. Usually, the noise moves along the length of the ductwork and then spills out of the mouth at the vent. In other instances, sound waves break out through the walls of your ductwork. They then spill into rooms.

You can use silencers to tackle the HVAC noise. However, you need to look at the system’s arrangement and other factors to get the best results.

The arrangement

The first step here is to inspect the spaces where you have the HVAC systems. It can give you a better idea of what you could be dealing with acoustically. You can then do an accurate mapping procedure of noise propagation. It must include the ventilation of equipment rooms, enclosures, and buildings.

Integrating noise management solutions like silencers into your system design then demands careful consideration. This is of aerodynamic pressure losses, fan selection, and space constraints. You don’t want to install anything if it won’t be effective or, even worse, will make things noisier.

The requirement, on one hand, is to lower the noise due to the gas or air flow. On the other, the solution needs to avoid compromising it. Also, the pressure drop needs to remain as low as it can. For this reason, silencers can be thought of as appropriate for all these factors. You can add them to the ventilation circuit and combine them with you machinery. This will acoustically isolate it in any direction.

HVAC silencers are a wonderful choice for applications demanding maximum insertion loss. It is the same for those needing rapid delivery, low maintenance, and low static pressure drop.

Talk to us if you want a discharge silencer

At Ventx, we have been designing and providing silencers for over a decade. As a result, we have all the experience and talent to provide clients with solutions that work. We can look at the specific issues in your property, including the equipment you use, the layout and materials, and operating conditions. This info can help to determine a solution.

So, if you need a discharge silencer or any other model, we’ll have no trouble getting you one. Feel free to speak to us if you have noise issues or are planning a new build or upgrade and want to ensure it will be quieter.

Many people incorrectly assume that air and steam is the same thing. However there are huge differences, especially in the level of energy. In fact, air will cause big issues with steam systems. As a result, it can be necessary to remove it. A discharge vent is a great option here, but you must think about the noise it can cause. You may also need a silencer to reduce the sound to a safe level.

The impact

The biggest issue with air in the steam system is it can dramatically reduce performance. It does this in two ways.

Firstly, it will lower the level of heat transfer. What typically happens is tiny air pockets will remain at the heat exchanger. Over time they create an insulating blanket because air is not a good conductor of heat. So, the amount of heat transferring from the steam can fall dramatically.

Secondly, air in the steam reduces the overall temperature. It can reduce it across the heat transfer surface. It can mean the system cannot achieve the correct process temperature. In turn that can mean processes that need to achieve a chemical or physical change won’t work.

How does it get in?

Air can get into systems in several ways. It is always there at start up, even if you try to begin by filling the whole system with steam. Sadly that will cause a vacuum and draw in air.

The main it gets in is via the feedwater. The water can readily absorb oxygen, nitrogen, and carbon dioxide, so it they will be present in solution. When it heats up, the fluid releases these gases and they go into the steam distribution system.

What to do?

The solution here is to vent the air to remove it from the system. A discharge vent with an automatic device is best here. There are manual ones but that puts more pressure on monitoring. There could also be a risk that the operator forgets to open the vent when necessary, compromising the system.

Ideally here you need the discharge to be as free as it possibly can be. That will maximise the amount of air removal. A good option is to have an automatic vent with a thermostat. It could detect the drop in temperature due to the presence of air and automatically vent it.

Think about silencing with a discharge vent

As you can see, venting the air is important to making steam systems function efficiently. However, the release of the gas can create a lot of noise. You need to think about this as the risk to people can be severe. In some cases the sound can be so loud it could damage the hearing of people nearby or cause major disruptions.

A solution is to use a silencer. They can be added to discharge vents and other parts of a system like pressure release valves. What they do is work to reduce the pressure and speed of the air flow. The goal is to bring them close to atmosphere. It will make it quieter when releasing air from the system.

At Ventx we excel at silencer design, manufacturing, installation, and more. As a result, clients can get a comprehensive service from us. We have very high standards and prioritise safety. So, if you need a silencer for a discharge vent, please contact us. We will be more than happy to assist you, regardless of how you use steam.

Noise pollution is a tricky thing to counter. Different machines produce differing levels of sound. The setting and actual use can also exacerbate it. We have a solution though; our high quality silencers. Ventx designs and manufactures all kinds of models to handle noisy conditions. They include our blow down silencer solutions and various others.

The huge costs of noise

Were you aware that noise pollution costs our economy roughly £20billion in health, social, and economic costs? At first, sound might seem like some unimportant invisible threat. However, the truth is that it is one of the biggest environmental causes of ill health. Air pollution is the only thing that beats it.

Just perk your ears up and you will discover that noise pollution is all around us. It could be the busy traffic on the streets or the bustling sound of people around you. You often can’t avoid it either. Surprisingly, the noises are so harmful that environmental noise causes roughly one million people to lose their lives each year. This is according to the World Health Organisation (WHO).

A myriad of health issues and problems have links to noise pollution. Thus, you can observe a substantial negative impact to the world and economy. For instance, heart disease derived from daytime traffic sound exposure costs around £1,183m per annum.

Meanwhile, there is tinnitus from leisure/traffic noise and hearing loss coming from loud music. They cost £52m per year and £38m per year respectively. At the same time, night-time and daytime noise can lead to slower learning in kids. This a £252m cost per annum.

Extra costs with amenity

There are extra costs because of the loss of amenity too. We are referring to the conscious displeasure of everyone exposed to the sound. Situations like these include noises influencing house prices and the cost of reduction measures. Not to mention, there is sleep disturbance. Loss of amenity via noise pollution is roughly valued at £2-3b a year.

Research shows that individuals living close to roads or airports with lots of traffic report more headaches. Also, they take more sleeping pills and are more likely to get into accidents. This is because they are weary and may not get enough proper rest.

Noise pollution also has a negative impact on our productivity. This is though issues with communication, fatigue, and distraction. Such a loss of productivity amounts to around £2b annually.

Talk to us if you need a blow down silencer

At Ventx, we’ve worked with a large number of clients to tackle their various noise problems. Using the high quality equipment we design, we have been able to transform their workplaces. Thanks to us, they are now much more tolerable to be in for employees and visitors. Plus, the level of sound that escapes into the environment.

So, if there is anything we can do for you, whether it is a blow down silencer, vent silencers, diffusers, or other models, please let us know. We have experience from numerous noisy industries, ensuring clients can rely on us.

We are a business that provides specialist silencer products. These devices, if you don’t know, minimise the noise from various forms of equipment. For example, you can have them for boilers, generators, and pipelines. They allow you to carry on working in a much safer environment. Our team is able to provide blow off silencer designs and many more to suit various needs.

Steam blowing is a practice that can be great for cleansing pipe systems. Here, you remove contaminants from your pipe network utilising the speed and force of steam. Thanks to the pipe’s contraction and expansion, steam also removes the mill scale.

The pressurised steam needed to clean the pipes is generated by firing a boiler. This is unlike the pressurise air-blowing method, which is close to the steam-blowing approach.

You need the right equipment here. For example, specialist quick-opening valves are necessary. In addition, you need debris-containing equipment, silencers, and steam-quenching solutions.

Why is steam blowing necessary?

An oxide coating manifests on the internal surface of pipes during the fabrication procedure in the hot working phase. Prior to the line entering service, you need to remove the mill layer from the system. One possibility if you don’t is that the debris may break off and head downstream during start up. These particles have the ability to undermine the pipe network’s instruments and similar critical areas. As a result, removing the scale is wise.

You will need to use noise control

One thing that is necessary during this process however is noise control. Too much fog and noise are generated when steam generators release steam into the environment. The sounds can cause problems with surrounding activity. They can be harmful to people too. Steam needs to cool by condensate to minimise noise levels.

Installing a conventional silencer that operates as an expander should be your first step. What this does is broaden the surface area and hastens steam cooling. This noise lowering practice comes in handy for continuous steam blowing at high pressure.

The second step is quenching. It functions using a water injection system. With this approach, steam loses heat and condenses. Later on, the condensation is partially recovered for use when you blow steam. However, reduction like this is only for low-pressure continuous steam blowing.

Talk to us if you need a blow off silencer

At Ventx, we have more than a decade’s worth of experience in silencer design. Furthermore, we have many years of experience in both quality manufacturing and acoustics. Using this, we are able to create some of the most efficient silencers.

So, talk to us if you need blow off silencer models. We can help you to reduce noise to make various operations safer, including steam cleaning.

There are a lot of problems that people can experience because of industrial noise. It can be physically and mentally damaging, having a long term impact on wellbeing. Plus, it can increase the risk of accidents and injuries in the workplace. Thanks to our silencer products, you can make your working environment and the wider area far safer. We provide models like natural gas silencers and many others. Each one serves a different purpose, but they are all efficient when it comes to minimising sound.

Expanding domestic energy reserves and a growing global demand have led to more interest in the oil and gas business. Companies both small and huge are scrambling to locate resources in commercial levels. This is to avoid dependency on foreign sources.

Such an aggressive approach has led to a broader search for natural gas and oil, two types of hydrocarbons. Searches are even going on in places once thought to be too near to commercial and residential developments. Despite the efforts to please landowners here, noise remains a challenge. What we want to do is explore the activities these companies partake in to obtain the hydrocarbons, and how they create noise.

Extraction

Firstly, there is drilling to extract the gas or oil. After geological data confirms the presence of hydrocarbons, the precise location of the well is chosen. It is then staked on the property. A drilling site and access roads are prepared for the rig’s arrival. Then the rig itself, as well as its ancillary, needs moving into place. All of this set up can be noisy.

For the next few weeks, the rig is going to drill into the well. The operation usually goes on 24 hours every day, and uses equipment that produces a lot of noise. As it is a temporary activity, landowners may tolerate the noise. There are cases though where noise reduction will be vital. In such scenarios, it is ideal to use tools like natural gas silencers.

Hydrocarbon production

Let’s say the well discovers commercial amounts of hydrocarbons. The drilling rig moves to make space for production gear to extract the resources from the ground. The oil or gas will either move via pipeline or could go into tanks.

For oil, extraction is a relatively quiet procedure. Contemporary pump-jacks are far quieter if you compare to their predecessors.

With natural gas production however, it is different. Noise is a big issue. You have to treat natural gas and compress it before it can enter the pipelines. Compression can be exceptionally noisy. The systems often run on site for many years continuously. Due to this fact, minimising the noise is critical. Thus, you need a way of lowering it, like a silencer.

Discuss noise and natural gas silencers with us

At Ventx, the solutions we supply benefit both their users and people living in the surrounding area. The latter is vital as loud industrial noise can travel very long distances. Furthermore, they help you to adhere to the established UK environmental standards.

So, if your plant is in need of natural gas silencers, please give us a call. We design bespoke ones to make sure they have the best impact.

At Ventx we support clients in different industries who have issues with noise. We have a wealth of experience and the skills to look at all kinds of sources, sound paths, and more. Ultimately we will provide a reliable solution to reduce the volume. It could be air vent silencers, diffusers for exhausts, or a choice of other models.

One thing you will see in a lot of industries is hydraulic systems. For example, they are crucial for construction, agriculture, aerospace, energy, and waste management. You can find them in things like lifts, steering, brakes, conveyors, and heavy equipment like printing and stamping machines.

The issue with air

One of the biggest problems with hydraulics is air. The issue is that it is compressible while the hydraulic fluid is not. It can have a massive impact on performance, efficiency, and even noise. In some cases it can compromise safety.

What you have to keep in mind here is accuracy is vital with many hydraulic systems. For example, let’s say someone is operating an excavator. The hydraulics control the movement of an arm. A valve opens to allow hydraulic fluid pressure to transmit, causing the arm to move. When it shuts, the armature stops. If there is no air in the system, the response times are instant and it uses energy efficiently.

However, if there is air in the system it can mean the arm is sluggish to start moving and doesn’t respond immediately to stop. It happens because the air needs to compress before the fluid can initiate the movement. That can be a big health and safety risk. It is also inefficient.

What to do?

Operators can use a number of methods to tackle the air problem. Firstly is hand bleeding to physically bleed air from the system. It can be time consuming though, meaning there can be a big hit to productivity. If air builds up quickly again, it also means you need to do maintenance more frequently.

A traditional alternative here was to drill small holes. The idea was they would allow air to escape. However, there are some major issues. Hydraulic fluid would also escape via the holes, resulting in big losses. Plus, it would have an impact on system efficiency, energy use, and even the level of tool breakage. The noise of air escaping could be hazardous too.

A newer option is to choose an air bleed orifice or air vent valve. The idea with both is similar to drilling holes, however they are much more reliable. The orifice can dramatically reduce hydraulic fluid loss. Valves open and close as necessary to release air. They are the better option in areas where you need to release high volumes of air.

Choose air vent silencers

One thing you may need to look at here is the noise. While it is great to remove air from hydraulic systems, you must factor in the risk. Depending on the conditions and size of the opening, venting the air could create very dangerous noises. It may be a good idea to use a silencer to reduce them.

Ventx is one of the best silencer experts in the UK. We can create solutions for all kinds of needs. Our experience covers some of the trickiest requirements, including oil and gas, energy, and manufacturing. We can apply it and our exceptional resources to find an effective noise reduction plan for you.

So, get in touch today if you need air vent silencers or any other solution. We can help, providing services that can tackle noise and also improve system efficiency and performance in some cases.

We have been working to minimise the problems that industrial noise causes for a long time. To do this, we supply special installations known as silencers or diffusers. They minimise the sounds that come from industrial equipment, HVAC systems, and more. We have different variants as well, such as the steam vent silencer for example. So, no matter what your needs are, we are confident we can meet them.

Water often reaches a temperature exceeding 100ºC (212ºF). When this happens, it releases steam. That can cause issues with lots of systems, especially in an industrial setting. In many cases there will need to be a vent to distribute or release the steam. It can be necessary for operations and vital for safety.

Venting noises

However, when you vent steam a number of things will occur that produce high noise levels. For instance, as the temperature climbs, gas flows become lighter and noisier.

A high mass flow will also lead to more sound. Any valve openings can result in noise level changes. Often, they become higher.

Lastly, the upstream pressure could become much louder than the downstream pressure. Consequently, higher volumes might happen.

Contemporary industrial settings have seen big increases in safety regulations. This is to stop workers from suffering injuries due to workplace dangers. Noise is an area where employers need to enforce strict rules. When steam vents make loud sounds, the hearing of workers can become damaged. Others can experience falls, or get into other accidents thanks to distractions. So, it is a very good idea to address the issue.

Why are silencers so important?

This is a great place to dive more deeply into steam vent silencers. When you introduce them, these devices can minimise noise to a level safe for human ears. They can also reduce the amount of sound that escapes a facility, helping the environment.

Several factors will dictate the silencer’s application. This includes how much attenuation is necessary and the allowable pressure drop. There are three separate applications; relief, blowdown, and vent silencers. The most appropriate model depends on the individual machine or system. You will require a silencer that minimises noise levels whilst making sure the equipment or system carries on working normally.

Talk to us if you need a steam vent silencer or other models

When you have to install a silencer, it is best to work with experts who know what they are doing. At Ventx, we understand that noise is an especially tricky element to accurately predict. Thus, we make use of advanced computer software. It enables us to see the levels that will be likely in each facility. Using the data, together with our experience, we can come up with the ideal solutions for everyone.

So, if you’re in need of a steam vent silencer or another model, please contact us. We can design one for you and also offer installation, maintenance, and more.

Industrial silencers are essential pieces of equipment for anyone working in noisy environments. You might not think that loud noise can do much beyond being annoying. However, this isn’t the case. It can cause irreversible hearing damage and also have a big impact on safety and performance. Fortunately, we are here to offer everyone easy access to the tools that can tackle the problem.

Most people will spend the majority of their days in specific workspaces. It could be an office, a workshop, or any other setting. Due to that fact, each one needs to be an area with the right conditions. This way, we can work to the best of our ability. We will get the results we need for the business to thrive.

However, in many cases there can be disruptive noises that aren’t really linked to the work setting. In some instances, you can’t help having noise. But, workers could find themselves experiencing a constant whirlwind of sound. The consequences can end up negatively influencing the wider business. What we want to do is go over two of the larger consequences of workplace noise pollution here.

Hostility

Firstly too much noise can be the cause of a hostile environment. It can be highly irritating to workers and employers. That can lead to stress when it is mixed with the workload and deadlines. What you can end up with is a negative environment and people ready to snap at each other. It can make it difficult for people to perform, especially if it causes barriers to communication.

A solution here is to have private locales for individuals to get away from the working atmosphere, especially if it is noisy. It will help to ease some of the tension and provides moments of comfort. If employees are not comfortable enough, productivity will suffer.

Non-privacy

Many workers need to have personal and confidential conversations. It could be with a colleague or a customer. They need to have these without the risk or annoyance of being overheard. Noise can be a big issue here. It can give the feeling of not having the necessary privacy.

According to estimates, half of employees feel irritated because of privacy concerns in the workspace. Noise pollution is a major concern, so it is vital that you keep it in check.

Choose industrial silencers when you need them

At Ventx, we use our decades of experience in various areas to bring you the ultimate silencers. Our establishment has been able to help various industries with their noise problems. The solutions we supply are both effective and cost efficient.

So, if you would like to know more about our industrial silencers, feel free to speak to us. We can offer models to suit an array of needs, catering for noises from HVAC systems, safety valves, and much more.

The food industry is one of the most important in the world. It needs to ensure there is enough supply to cater for demand. To do this there are a number of large operations to produce, manufacture, process, pack, and transport goods. An issue here is some of them can be very noisy. The loud sounds are hazardous to people and the environment. It may mean that businesses need to invest in solutions like industrial silencer products. What we want to look at in particular is noise in food processing and packaging.

Operational noise

The size and scale of equipment for processing and packaging food can make it very noisy. The speed also has a big impact on this. Conveying systems are a main culprit. They can generate a lot of noise because they need to move goods along very quickly to maximise efficiency.

The biggest risk is to people who need to work close to the equipment. They can find they are routinely spending hours in settings with very high noise levels. Without the right protection they could suffer hearing damage. In some cases it can be temporary, with a ringing in the ears. However, regular exposure or a single long period can make the damage permanent. It can cause tinnitus and even hearing loss.

Solutions

There are a number of things operators can do here to improve safety. The first is to ensure that employees have suitable hearing protection. It is generally the easiest option but it does not directly tackle the noise; it will still be loud but people will hear it at a lower level. They need the right kind of protection and must wear it correctly at all times in the area.

Often the best option is to reduce the noise level itself. One way to do this is to use an industrial silencer. You can get models to attach to various pieces of equipment and systems. The right design will reduce the sound.

Another thing to do is ensure systems take power from the mains. It is difficult to do this in some facilities because of the layout and infrastructure. That can lead to operators using generators instead. However, they can be particularly noisy. It is better to wire in to the mains.

Sometimes the best option is to upgrade the processing and packaging equipment itself. Older systems, especially conveyors, can be very loud. However, newer ones can have operational noise levels of around 70dB(A). That is nicely below the 85dB(A) danger level.

Our priority is safety, but the solutions we offer can also improve operations. For example, addressing noise from vibrations can lower maintenance costs and boost efficiency.

If you would like to look at the options for an industrial silencer and the benefits, please contact us. We are happy to advise and can devise a solution for you.

Ventx is the UK’s top industrial silencing expert. We support clients with noise control, whether it is sounds because of their equipment, transportation of gas or liquid, or other issues. To help, we can offer a safety valve silencer and other products. Here we strive to make workplaces safer and can also improve efficiency. Plus, we can support businesses with adhering to environmental standards.

A number of industrial operations rely on safety valves. They can control pressure drops with liquids and gases to prevent dangerous situations. For example, if there was no valve on a line transporting steam, the pressure could build to a point where it could rupture the pipe or explode.

The issue here is the valves increase the amount of ambient noise in an area. This happens in three different ways:

Mechanical vibration

Firstly, noise can occur because the flow of liquid or gas physically makes components in the valve vibrate. It can be surprisingly noisy, especially if the valves are the wrong size. In some cases heavy vibration can even increase the risk of damage.

Aerodynamic noise

Any interruption in the flow of gas in a system can result in loud noises. What happens here is the gas decelerates, expands, and changes direction. It results in turbulence and noise. Unfortunately some system designs create obstacles or obstructions that cause the aerodynamic issue. For example, it can happen due to gases flowing into a safety valve. It is also common when there are bends in pipes.

Hydrodynamic noise

Systems for transporting liquids can also suffer from noise problems. The issue here is usually cavitation. What happens is vapour cavities form and collapse within the flow of liquid. The collapses generate a shockwave and cause the sound. People who have experience with it often say it sounds like gravel flowing through the pipe.

Treatment

It is important to treat any noise in these situations. In some it may be necessary to install a safety valve silencer or path treatment. In others you may need pressure management solutions or even source treatments such as inline diffusers.

There are a number of benefits if you do tackle the noise here. Most importantly you will improve worker safety by ensuring they don’t have exposure to the sounds. That is a responsibility every employer should take seriously.

In addition, in some cases the noise treatment can reduce the need for costly repairs and downtime. There is a lot of pressure on components and instrumentation here. So, they may need repairing more frequently. That can be very costly. It is better to tackle the noise and improve the operating conditions.

Talk to us to design a safety valve silencer

At Ventx we appreciate how vital safety valves are. However, we also know about all the negatives associated with high ambient noise. We can tackle this with solutions like silencers and diffusers. We have a long history in the industry and can serve clients with all kinds of facilities, including exceptionally noisy oil and gas or chemical plants.

So, if you need help, speak to us and see if a safety valve silencer is the solution or if another model would be better. We will select the best one for you.

Sterilizing waste can be vital in many situations. It is especially true with medical and laboratory materials. Autoclaving is a great option here as the high pressure steam can render items non-infectious. However, there is a risk the equipment can be noisy. Luckily, Ventx has the expertise to provide an autoclave silencer. We can design it to tackle the sound but maintain the performance.

Safer handling of waste

Medical and laboratory waste can pose a significant risk to health and safety. For example, it could be biological cultures for studying infectious diseases. They could be live viruses or bacteria. It could even be old medical implements like needles or scalpels with blood contaminating them.

The main issue here is the waste may need handling several times during disposal. For example, it may go from the first person to use and discard the item to someone collecting the waste to ship for disposal. From there it could come into contact with the lorry driver and people at the other end who unpack and process it. So, there is an even higher risk of accidental exposure at any point.

Good practice to minimise the risk is to sterilise the waste at source. A trip through an autoclave can do that. The steam would kill viruses and bacteria. As a result the waste would be sterile and non-infectious.

A number of different items are compatible with autoclaving. For example, you can put culture dishes, items made of borosilicate glass, stainless steel, PP and PC plastics, and more in. However, you can’t autoclave household glassware, PS, PE, or HDPE plastics, or materials that contain hazardous substances like bleach, corrosive chemicals, or flammable liquids. Some items will require longer hold times, such as items with film covers.

Using an autoclave

It is important to be careful when using autoclaves. There is a risk of injury due to the heat and high pressure. The noise can also be hazardous in some cases. It may even require the use of an autoclave silencer.

Operators here need to ensure they keep on top of equipment maintenance. There should be regular checks and services. Plus, equipment should only be used in line with the manufacturer’s guidelines. It is important to follow the recommendations for things like load size, cycle settings, and temperature.

It can be necessary to use heat sensitive indicators with autoclaves too. What they do is show that the autoclave reaches the correct operating temperature. Plus, you may need deodorisers if the autoclaving is causing bad smells in the area.

Talk to us if you want an autoclave silencer

Ventx supports all kinds of businesses. We appreciate that autoclaves can be vital in large and small labs, hospitals, health clinics, dental practices, and research centres. However, often the spaces can mean people need to work in close proximity to the equipment. Noise can be a serious hazard in these cases. It makes using silencers even more important.

If you do use this equipment and need an autoclave silencer, we would love to help. The solutions we offer are bespoke so they give you the maximum benefit. We also choose the materials carefully for longevity. You can contact us if you need any help with noise control here.

Steam is vital in a number of industries. It can be necessary for generating heat, power, or doing various tasks like sterilisation. The most efficient way to produce it is the use of large industrial steam boilers. However, there are safety concerns here. Site owners, operators, and managers must look at them and have plans in place for maximising safety. It may also be necessary to choose a steam boiler silencer.

What is the risk?

The main issue with big steam boilers is they generate very high temperatures and a lot of pressure. The presence of water is a concern too. In this situation there is a real risk of accidents.

What you have is conditions that put stress and strain on the boiler and pipes. Over time the materials here can fatigue and weaken. Corrosion is also a big worry because it can make metals weaker. In the worst cases leaks, ruptures, and even explosions can happen.

A serious issue with a boiler can cause major injuries to people in the area. There have even been cases where explosions cause fatalities. In addition, an accident like this can seriously damage the facility and any plant or merchandise in it.

On top of all of that, these boilers can be very noisy. Most notable here is venting any excess steam to atmosphere because it can create a sudden excessively loud noise. It could permanently damage the hearing of people nearby. So, a steam boiler silencer can be vital.

What to do?

The major thing with steam boilers, as well as looking at additions like silencers, is to focus on safe operation. A number of things come into play here. For example, you need to look at the operations, location, maintenance, and system control.

One thing some operators forget to do is adapt how they deal with their boiler. Initially boilers are chosen to suit very specific operating conditions. However, in time there may be changes here. Perhaps you now need more steam than you did at first. Or you may have modern electronic controls and not manually check the boiler as often. Any alteration like this can bring a safety risk.

The best thing to do is be proactive. Do regular risk assessments to make sure any risks are within safe limits. Then, if there is a change in operations, check how the boiler behaves and any additional stress or strain. Plus, make sure you have competent people with the right training to check the boiler.

Buildings all over the UK will be relying on their heating at the moment to tackle the winter cold. However, this use is probably also once again highlighting an issue many people have; HVAC noise. You may find it is a lot noisier with sounds coming from vents and ducts. It may mean you need to look at repairs, cleaning, or even installing silencers. Ventx can help with industrial silencer design, delivering the best results for clients.

The problem with the noise

In many cases HVAC noise won’t be harmfully loud. However, it can still be a major issue in a number of settings. For example, it may be difficult for people to work in offices if there are annoying noises. The sounds could be distracting and mean they can’t focus. It can be even worse for things like hotels and restaurants. Guests might not be able to relax with the sounds. It could seriously affect your business by making people not want to stay or deterring them from returning.

What to do

HVAC noises can occur for a number of reasons. Some can be due to issues with equipment such as broken fans. It could also be because of dirt in the system or even problems with the actual duct design and layout.

The first thing you should do here is inspect the system. It should help you to spot potential problems. If everything looks in order it is a good time to look at industrial silencer design.

Location is crucial

The most important thing to think about if you do need silencers for HVAC systems is location. You need to find the most effective spots, especially if you want to maximise noise reduction. Here you need to keep a few things in mind, including the type of silencer and how far areas are from the mechanical room and noise sources.

Breakout noise

A particular thing to think carefully about is the breakout noise. The majority of the sound from HVAC systems will come from vents and other openings. However, some will come directly through the walls of the ducts. That is how it gets its names because the sounds are breaking out.

While installing silencers can help with sounds from vents and things, it can be harder to address breakout noise. In some cases you may even make it worse because of the change in the flow as air enters and exits the silencer. This is another reason why you need to think carefully about where you install the silencers. Ideally you will have them where it won’t have a negative impact on breakout noise.

Industrial noise reduction is something we have specialised in for a long time. Specifically, what we do is supply a host of silencers. These installations work by minimising the noise from machinery and systems. They can tackle different types of vents, exhausts, intakes, and more. We have different models for individual environments too. As a result, we can cover all the angles for our clients.

Employers have a moral responsibility to guarantee that their team remains safe in the workplace. This may appear obvious, with most people seeing it as standard. However, it is worth considering the legal obstacles surrounding noise at work. This is in addition to the compliance legislation that aims to protect employees. As an employer, if you don’t take your responsibilities seriously, you could be open to risk, a legal one.

Let’s say that you fail to keep up with the constantly shifting risk compliance legislation. New rules demands that everyone has responsibilities and duties surrounding health and safety. The implications for failing to follow the guidelines should not be disregarded or ignored. Failure to adhere to the regulations might result in legal action. This not only means liability for compensation, but prosecution under the Health and Safety at Work Act.

One of the biggest workplace dangers is noise. This could be a shop assistant working in a store with background music. It could also be construction workers using noisy equipment. What you must address here is what makes workplace noise dangerous. You also need to look at the measures you must take to lower the danger of exposure. This would prevent long term harm to employees.

Checking employees’ hearing

Conducting hearing checks is one of the ways you can help keep employees safe from noise. You should perform these if there is a danger of noise levels damaging hearing. It will warn workers who could be experiencing early hearing loss symptoms. Additionally, this lets employers see if their noise management solutions are suitable. If they are not, they can update their protection accordingly. They can install solutions like silencers.

Hearing checks must be performed by a competent party. They must do so where employees regularly have exposure to noise levels surpassing the action values. After the employer obtains a baseline figure, it is vital that frequent checks on hearing be done. The interval between these will depend on multiple elements. Examples include risk levels and if a check reveals that hearing loss is evident.

Work with us to look at industrial noise reduction

At Ventx, we manufacture noise reducing solutions for a host of industries. Our team makes sure that everyone is able to get their hands on solutions that are practical and cost effective as well.

Noise might be a particularly difficult factor to accurately predict. Fortunately, we use special acoustic modelling software. With it, we can design suitable silencers for every client.

So, if you need help with industrial noise reduction, contact us today. We are a company you can rely on, especially if it is a loud industry such as oil and gas or manufacturing.

Industrial noise can cause many health issues, some of which are permanent. Ours is a business that aims to prevent such damages. To do so, we supply a wide range of industrial silencers. Using the likes of our steam vent silencer designs, you can prevent your facility from producing harmful levels of noise.

Of the many forms of noise that exist, those coming from steam vents are definitely among the worst. Sound levels here can be extremely high. This is especially true if the steam is very hot, high pressure, and released directly to the atmosphere.

The harm

Loud industrial noises from steam are harmful in a multitude of ways. The most well-known is that the sounds can damage hearing. Merely one incident of exposure to an extremely loud noise is enough to generate problems.

To give an example, noises at 140dB or more can lead to pain and hearing loss. A mere 15 minutes with sounds ranging from 110 to 120dB can lead to damage. Lower noise levels also have the potential to cause problems with exposure for long enough. A few hours with sounds at 85dB can cause hearing harm.

One other reason why noisy steam vents are hazardous is because of how distracting they are. The noises can cause individuals to lose focus easily when working close by. This can result in massive complications if they are doing something that demands concentration. Examples include working on ladders, driving vehicles, and using power tools. One momentary distraction is all it takes for things to go wrong.

Loud noise isn’t only damaging to people as well. You might use equipment that is sensitive to sound waves. If you don’t take the right steps, there is a chance the noises will damage said equipment.

The details you must consider

There are several details you need to consider here. For instance, the noise coming from steam vents can become far louder as temperatures rise. If your operations generate high heat levels, you will want to use a steam vent silencer.

Something else that will have a big effect on the noise is the flow rate and quantity of steam. When there are higher flows and more steam, there is more noise.

You might also encounter some huge problems if a disparity exists in the upstream and downstream pressure. If it is far higher upstream, there can be louder sounds downstream as the pressure adapts.

It is vital to note too that there can be larger complications with systems that have control valves. They are often required as a safety measure in case there is a pressure build-up. When they open though, it is likely they release steam at extremely high flow rates and pressures. What you end up with are some very loud noises.

Let us design your steam vent silencer

At Ventx, we have more than a decade of experience in industrial silencer design. Furthermore, we possess over four decades of acoustic knowledge, as well as 35 years of quality manufacturing. Putting all this together allows us to produce the highest quality silencers on the market.

If you need a steam vent silencer, please contact us. We can design models for all kinds of needs, including boilers, safety valve systems, and more.

A holistic approach to noise control provides the best results. What you need to do is look at sources of noise, the paths noises take, and how the sounds can escape through things like ducts and vents. You can then ensure you have suitable measures in place. This can include silencers, enclosures, and materials to dampen vibrations.

The latter is what we want to focus on in this article. Vibration can cause an excessive amount of noise. It primarily comes from mechanical sources, such as plant, boilers, and any systems with fans. You can also find vibrations coming through frames, mounts, and even floors in some industrial properties.

What to do?

One of the ways to approach noise control here is to look at vibration damping. There are several options, but they all have a similar basic idea. What you do is use thin materials to dissipate some of the vibration, hence reducing the sound.

There are two common techniques to look at here. Firstly you can go for unconstrained layer damping. This involves applying a high damping material such as rubber. When a vibration occurs, the material will stretch and dissipate some of the energy as heat. It can make the noise quieter.

The second option is constrained layer damping. It is an interesting option where you create a laminated sound deadened panel by using two metal sheets with a high damping material in between. This arrangement can dissipate almost all vibration energy. As a result, it can be far more efficient.

You need to make sure you choose the right option here if you want to maximise noise control. As we just said, the second method is more efficient. It also has advantages in terms of being low maintenance and more hygienic. However, unconstrained is easier in terms of retrofitting and is cheaper. You can still achieve a good reduction in noise here, generally from 5-25dB(A).

Applications

You can use vibration damping for a huge array of applications. For example, it is viable for noisy chutes, hoppers, and conveyors. In addition, you can use it to address noises vibrating from tanks, machine guards, and even chiller panels.

There is a limitation to keep in mind here though. As sheets get thicker, the efficiency drops. It is much harder to reduce vibrations and noise if the substrate is over 3mm thick.

Speak to us about noise control

While vibration damping can be a really useful method of tackling noise, you may need others too. For example, silencers may be necessary for intakes, outlets, and more. You can combine these different options to get holistic noise reduction.

At Ventx we specialise in silencer design. Our years of knowledge and market leading resources ensure we can support clients in many industries. We can work with you to prioritise noise control to improve safety and performance. So, if you need help, please contact us.

There are a number of different ways to tackle industrial noise. For example, you could choose acoustic enclosures to prevent it from escaping a specific area. Or you can use silencers to reduce the decibels. They can work in different ways, including turning sound in to heat (absorbing) or reducing the pressure (diffusing). A diffuser silencer can be the best option in many cases.

How do diffusers work?

The basic idea here is that high pressure gas can enter the silencer and expand. This brings the pressure down and is far better than releasing it directly. It can reduce the noise because the lower pressure will be closer to the atmosphere.

What you will generally find with diffusers is a pipe that will funnel the gas into the centre of the silencer. There will usually be small holes in the pipe so the gas can expand and diffuse as it moves outward. As it does, the pressure will come down. It will then meet the shell of the diffuser silencer and can be expelled.

Some silencers have multiple stages here for the gas to diffuse. For example, there may be a secondary expansion step with that has a higher number of even smaller holes. What happens is the gas comes through the diffuser pipe, expands and loses pressure when it enters the silencer, then expands and loses even more pressure when it hits this secondary diffuser.

In some cases the diffusers can feature even more expansion steps. It all depends on the pressure drop you need to achieve. Sometimes you may even need an insert of filler material. Flow resistant stainless steel can be a good choice here. You can have it between the expansion steps.

There are also situations where you need one more stage of silencing here. If there is a lot of noise to tackle and you still need to reduce the pressure, the silencer may need an absorber above the diffuser section.

Advantages

There are some fantastic benefits with a diffuser silencer. The most notable is you can often choose a small, light design. The advantage here is you typically don’t need to accommodate sound absorbing material. As a result, the silencers can be smaller and lighter. In turn that can make installation easier.

In addition, you can obtain a really good level of sound reduction. It is common to see this be as much as 50 dB(A) without sound absorbing material. It can be possible to achieve more than this with the right designs.

You can use this kind of silencers for a huge array of applications. For example, they are common for natural gas pipelines and power stations that need to vent hot steam. You can also see them at places like paper mills. If any operations have safety, gate, or control valves, they can be useful here too. You can even find them on boiler condensers.

Speak to us if you need a diffuser silencer

At Ventx we understand the benefits of silencers. They can make industrial operations much safer, especially when they generate a harmful level of noise. That is important for worker health and safety as well as the environment. Reducing the sounds can also be vital for performance, especially if you have any sensitive equipment.

So, ask us about designing silencers. We will use specialist software to analyse your operations and the noise level. The data will help us to decide what model would be best for you. It may be a diffuser silencer, an absorptive model, or one that combines both. Whatever the choice, we will deliver the best results.

Industrial noise pollution is a problem that many businesses experience. It also hurts neighbours and the environment. However, it is not an issue everyone has to put up with. For starters, doing this would put everyone’s health at risk. Secondly, there are specialist tools out there. They can minimise the noise that facilities create. Ventx is a business that tackles the sound by providing vent silencer models as well as various other designs.

Sound waves

You can think of sounds like the ripples in water when you throw a stone into it. The impact creates ripples which travel outward in each direction. Then, if you were to take this pool of water and squeeze it into a canal, these ripples would be channelled to flow through the canal’s length because they cannot escape the sides.

This is what occurs when you link your ductwork to a fan. Those sound waves originating from the fan are getting channelled through it. The ductwork functions as a barrier, stopping the sound waves from escaping outwards. However, there may be some breakout sounds.

Returning to the analogy, as the ripples move through the canal, they are still attempting to protrude outward in each direction. Some will fall on the walls of the canal or shore, producing a little noise. In the same way, breakout noise would be the sound waves attempting to escape via the duct.

The fan silencer’s role

It is here where a fan silencer comes into play. Installing one in the duct will aid you in absorbing a number of these sound waves. The quantity of them silencer’s absorb will depend on the acoustic media. Other factors that will influence this include the silencer’s length and its open area.

When sound waves enter silencers, the perforations existing in the baffle let them expand. It does this into the acoustic media. The material is comprised of millions of air pockets. When the sound waves impinge on them, it leads to the molecules moving and colliding with one another. That turns the sound energy into heat. It can then dissipate without noise.

The more baffles you are able to place within a silencer, the more noise you can reduce. At the same time, this will heighten the pressure drop. All fans generate pressure to push air forward. However, if there is an obstruction it can produce resistance in the air stream. So, a fine balance exists between the resistance of airflow the silencer creates and the pressure drop you can permit.
