Ventx Ltd

No one wants to deal with noise pollution. However, it is an issue that always seems to pop up. To counter it, we supply specialist tools. These would be our silencers. They allow their users to control the amount of noise that comes from their facilities. We have steam vent silencer designs as well as a number of others.

A fact you may not know about silencers is that they all have some interesting mechanical characteristics. There are several notable sections.

The silencer shell

Firstly, there is design pressure. This is normally greater than or equal to the permitted silencer back pressure.

Up next is design temperature. Typically, it is set to cover the maximum of the gas and ambient temperature ranges.

Minimum casing thickness is another one. The purchaser can set this or you can leave it to the vendor to decide.

Inlet assembly and diffuser

We will move onto the inlet assembly and diffuser section next. Here we will begin by looking at the hydrostatic testing first. This is not actually a requirement. However, it might prove necessary by regulations for objects that must follow specific codes. If you include the test, it is usually performed at 1.5 times design pressure.

The second thing we will talk about is registration. Diffusers and inlet assemblies created under certain codes might need registration so they satisfy the regulations.

Accessories

Finally, we have the accessories section. Up first is silencer discharge. The majority of silencers get installed outside. They discharge to the atmosphere directly.

We will finish things off by covering weather protection because it can be vital. If necessary, the protection options are normally 90º, 45º, and whistle cut cowls.

Do you need a specific steam vent silencer?

At Ventx, our industrial silencers are able to benefit their users in many ways. They can also do the same for any visitors to the sites and other stakeholders.

All of our models, including the steam vent silencer, are available from our UK base. We design each one to suit the specific needs of the client. As a result, we ensure they get the best level of service and silencing.

If you get into contact with our team, you can ask questions and learn more about us. Then, if you choose to get a product, we can design and deliver it for you.

All kinds of industries have to think about noise control in one form or another. It may be they need to take steps to reduce how noisy it is on site to protect employees. Or, it could be there are concerns about how loud sounds could be affecting nearby people and wildlife. It may even be that noises on the site are hurting efficiency and productivity. Whatever the case, there are lots of different products you can try.

Silencers

At Ventx we specialise in a very specific products – industrial silencers. We can create a wide array of different models to suit all kinds of needs. For example, we can design inline models and various other styles. We can cater for various things, including fans, exhausts, ducts, control valves, and gas or steam injectors. In each case we ensure that we design the silencer to suit the application.

Other options

However, there is a lot more to noise control than these. Industrial clients could also choose things like:

Enclosures – a specialist noise control enclosure could contain noisy industrial equipment so that sounds cannot escape.

Acoustic ventilation – heavy equipment like generators, compressors and motors can be very noisy. Here it may be a good idea to have a full ventilation system with acoustic lining.

Blankets – in some cases it is possible to soundproof noisy equipment and systems by simply using a thick wrap or blanket.

Vibration isolation pads – in a number of cases the loud noises are because of vibrations in equipment. These pads can help to dampen it and also help to preserve machinery.

Acoustic louvers – while using silencers is the best option for ducts, it is not the only one. There is also the option to install these louvers. They can provide attenuation and help to reduce the noise that escapes.

Talk to us about noise control

At Ventx we recommend that our clients take a holistic view of their facility. That way they can devise the most effective plan to tackle the noise. It may be that they need to utilise several different products to get the noises to an acceptable level.

When it comes to noise control and silencers, we are always happy to help. Clients in any kind of industry can contact us for advice. We would be happy to assist you.

We all know how annoying loud noises can be. This is true whether it is at home or at work. However, in some cases the sounds can be very harmful. One very loud sound or repeat exposure to unsafe levels of noise can cause hearing damage and more. That is why there are noise limits in place in many industries. The operator may need to invest in products like a diffuser silencer to help keep sounds below this limit.

How loud is too loud?

Some people find it difficult to say when a sound becomes too loud. The limits can be different depending on a number of things, including proximity to homes and how close people are to the source on the site.

To give you a better idea of noise levels, here are some typical sounds. Firstly, keep in mind that complete silence will be zero decibels (dB). If a sound is ten times louder it will be 10 dB. Something like a quiet whisper is around this level so it is not harmful. A normal conversation will be around 60 dB. Again this is not harmful.

Noises pass into a harmful range when they are above 85 dB. Regular exposure to sounds over this level can cause hearing damage. Some examples of sounds in this range include lawnmowers (90 dB), blenders (up to 90 dB) and electric drills (95 dB).

Sounds over 140 dB can cause immediate hearing damage and be very painful to even hear. A good example of a sound that is this loud is a firework.

Distance is vital

While the amount of exposure is important, distance is also vital to determining if sounds are too harmful. The further away a person is from the source, the more chance it has to diffuse and come down to a safer level. Take the example of the firework above. Because they explode high up in the sky, the sound when it reaches people standing on the ground is less intense and safer.

It is important to keep this in mind on industrial sites. Sounds at the source may be incredibly loud and dangerous to people in the area. However, they may be safer further from the source. In this situation, it is vital to get a good idea of where the sound exceeds a safe level. From this point on people need the right hearing protection and should limit their exposure to the sounds.

Talk to us about a diffuser silencer

At Ventx we work very hard to help our clients tackle noise issues on their sites. We understand all the different sources of the sounds, whether it is heavy machinery, venting, or a HVAC system. This knowledge means we can suggest the right solutions.

One of the best options is to use silencers. This can help to cut noise at the source or where it would emerge into the open. We can design unique models to suit any need.

So, if you need a diffuser silencer or another style, please contact us. You can tell us about your facility and we will design the right products for you.

Many large industrial, commercial, and public buildings would be very unpleasant if not for the duct system. This helps to remove exhaust air as well as harmful and unpleasant fumes. At the same time it supplies clean air. However, the issue is that the ducting can generate a lot of noise. Even a slight vibration can become really loud. Luckily, you can use an in-line silencer or a series of them to reduce this.

How does it work?

The silencer fits easily into the duct. It can provide attenuation and sound absorption thanks to the media within it. At Ventx we can design bespoke ones with different silencing media to suit various needs.

The design must be correct to ensure it can effectively reduce the amount of noise. In addition, it must fit correctly. If it is too small it can make the noise worse rather than dampening it. On the other hand, if it is too large it will cause issues with installation.

Applications

There are lots of different potential uses for an in-line silencer in a duct system. For example they can fit into both supply and return ducts. Here they just need to reflect the direction the air is flowing.

The noise from ducts can be the loudest at fume and smoke exhausts. This typically happens because of the rapid change in pressure. Luckily, you can install silencers here to tackle the issue.

Loud noises can also originate from air handling units and fan plenums. However, you can install silencers close to them to reduce the noise here. You can do the same close to terminal and mixing boxes.

Some people plan for how noisy ducts will be and choose acoustically lined ones. While they can be effective at reducing noise, they are more expensive than choosing a reliable silencer.

Come to Ventx for an in-line silencer

We are proud to be one of the best silencer designers in the UK. Clients in all kinds of sectors and industries rely on us. We always design products that will suit their needs, reflecting the size, shape, and configuration of their ducts.

So, if you want reliable silencing products from an expert team, get in touch with us.

In order to effectively reduce the noise your facility produces, you need the proper tools. Our company happens to specialise in this area. We use the latest software to create utensils that are perfect for you. Our team can use it to design the ideal vent silencer or something similar.

All air vents make a noise when the system fans are operating. Such a situation is normal. Of course, some systems produce louder sounds than others do. They are quite a bit louder actually. To give an example, a home with sufficient return air ducting shall be quieter than a set up with one big return grille. This is one that is cut directly into the equipment’s return duct. There is technically nothing wrong with this but it will be on the louder side.

A lack of return air

The complaint that pops up the most with these systems is that there is a tuning fork sort of noise. Normally, this is because there is a lack of return air. However, it is not always the case. The system must pull more air. Therefore, the velocity and pressure increases. This leads to an increase in sound. By introducing an increased level of return air, the pressure goes down. The system does not have to function as hard. As a result, it quiets down.

You are probably wondering why there may be a lack of return air. It could be that the ductwork was not installed properly or is just undersized. The answer could be as straightforward as having a blockage in the air filter. The system must move a certain degree of air. If there are blockages, then there will be a pressure problem. This causes the noise levels to increase.

What kind of vent silencer do you need?

At Ventx, we can provide you with solutions to help control the noise coming from your own vents. Our team has had the honour to work with a large variety of clients over the years. Whenever someone comes to us asking for help, we go out of our way to provide them with a suitable silencer.

If you require a vent silencer as well, please let us know. Just tell us about your systems and we can design a suitable solution.

Ours is a business that specialises in attenuators and silencers. Due to their role of reducing noise, it is vital that the customer receives one that is suitable for their needs. To create the perfect design, we use acoustic modelling software. This allows us to carefully match the product to the application.

In new build residential developments, mechanical ventilation noise is a common source of complaints. Many of these buildings use MEV and MVHR systems that operate nonstop. The homes rely on the systems for their ventilation, so they are essential.

MVHR can cause the most problems. This is because air supply ducts run to noise sensitive rooms directly. However, sounds from extractors within wet rooms can annoy people too. Fortunately, there are ways to help minimise the chances of noise issues.

Specifying limits

One possibility would be to specify noise limits so the sounds are not harmful. You should design MEV and MVHR systems to stick to suitable noise levels in all habitable spaces.

To guarantee decent acoustic conditions, mechanical ventilation noise should not pass certain limits. This is according to Building Regulations Part F. For living rooms and bedrooms, it is 30 dB LAeq,T. For less sensitive rooms, it is 35 dB LAeq,T. You should achieve these limits with your units operating at background ventilation rates. This is as a minimum but you can try to reduce the noise even more.

Construction

Careful design will help you here as well. Your systems have to be carefully constructed to reach the necessary noise limits. It is best to ask M&E equipment manufacturers and designers to verify that their designs can achieve the limits. Depending on the system’s design, you may also need some extra mitigation. This includes using in-line attenuators.

Designing specific attenuators for any need

At Ventx, our products allow you to control the noise coming from many forms of machinery. We understand that the needs of the customer can be as unique as the project. Therefore, we always have people on hand to ensure you get a complete service all the way through. We will also see to it that your silencer lasts for years to come.

So, if you need any help, don’t hesitate to contact us.

Most of us will know how noisy HVAC systems can be. You may notice them at work, while you are in a public building, or even at home. The sounds can be very annoying or even harmful in some cases. However, there are ways to tackle the problem. For example you can use an attenuator or silencer to reduce the noise.

What makes the noises?

While most people know the HVAC systems can be noisy, do you know what causes the sounds? There could be a number of different issues. Individually they can cause noise, but collectively it can get very loud.

Common causes of noise from the systems include vibration of the ducts and fans. The latter can be very noisy, especially if they spin at a high rotation and the fins move.

Some of the loudest sounds can occur because of air changes within the system. For example, the noise can be very loud if there is a big drop in the pressure. This can occur at vents, exhausts, and if there are obstructions in the system.

A lot of people think that HVAC systems will only be noisy when they get old. While older systems can be louder because of wear, dirt, and poor maintenance, new systems are not going to be silent. In fact, they can be noisy because of issues like poor installation and a bad design. Regardless of the age, loose fittings can vibrate and produce noise.

Resolving the issue with an attenuator

At Ventx we have a lot of experience with loud systems including HVAC and industrial equipment. Our goal is to offer the right sound reduction solutions. We design them with care to make sure they will be reliable and deliver great performance. There are various types of attenuator to choose from, including cylindrical and rectangular. As a result, we can offer the perfect shape for any system.

If you have any questions about attenuation or the products we offer, please get in touch.

The goal of our company is to offset the issue of industrial noise pollution. To do so, we design silencers that enable their users to control the level of noise their machines produce. There are various models that we specialise in, including the intake silencer. In addition to keeping you safe, our merchandise shall ensure that you are following the law.

With HVAC systems, you must do whatever is possible to keep noise levels at a minimum. Careful design and installation goes a long way here. In fact, the first is essential.

However, these systems age just like everything else does. Parts begin degrading and noise levels rise, even in the best designs. Furthermore, alterations to the building’s inner layout can influence the system’s function. This is especially true when you alter the size of a room.

The fix

For a system that is noisy overall, the fix could be an easy one. You might simply need to minimise the air pressure inside your system. This may not work though. In this scenario, you can try a few simple steps to minimise the fan noise. Lining the ductwork with fibreglass liner or installing mufflers could work. A better option may be to install a silencer though.

Dampers

The dampers within a variable air volume system can result in noise concerns too. They might only close partially. When this happens, the same level of air shall force its way through a more compact opening. The difference is that it will do so with higher velocity. Things can get quite loud as a result.

Dampers with broken gears can also generate noisy banging sounds. Once the control system conveys a message to close a damper, they begin the operation. Afterwards, the gears slip, producing noise.

Creating a bespoke intake silencer

At Ventx, we have decades of experience of quality manufacturing and acoustic knowledge. We build on this to bring you the very best silencers money can buy. In addition to being practical, our solutions are cost effective thanks to our great prices.

If you need a unique intake silencer, contact us today – we will design it for you.

With noise reduction, you really need a tool you know that is going to work. This is our area of expertise. Using our state of the art acoustic modelling software, we can create something that fits in with your own systems. In other words, you can have an in-line silencer, or another design, that perfectly matches your requirements.

If there is one thing that annoys people in the workplace, it is noise. This is not the greatest of news for employees. We say this because huge noise levels can result in more than simple irritation. There are actually several ways it can influence people. Read on to discover what some of them are.

Stress

For one thing, noise stresses people out. There is more to stress at work than office policies and deadlines. Noise leads to stress within our bodies too. Prolonged exposure to specific loud sounds cause psychological stress responses within us. This includes heart rate and blood pressure spikes. It is even possible to be affected by the sounds we hear inside offices.

A costly affair

Loud noises are a costly issue too. According to World Health Organisation estimates, the annual cost to Europe from considerable noise levels is £30billion. This includes productivity losses, healthcare costs, and lost working days. Inside that figure is a considerable amount of sick days. Compare it to home workers, and those in an open plan office take 70% more sick days.

Loss of focus when multitasking

You can also expect multitasking to be harder. The more you try to multitask, the greater the chance of environmental sounds becoming a distraction. Habitual multitaskers are more likely to lose focus because of it. In addition, once they lose it, it is harder for them to get their first task back into their heads.

Let us design an in-line silencer for you

At Ventx, we use our silencers to help reduce the physical and mental impacts loud noises have on people. Using the right type of silencer, you can manage the noise level from numerous machines. You can also silence HVAC systems and more.

If you ever find yourself in need of silencers, whether it is an in-line silencer or another type, be sure to contact us. We can design a great piece of equipment for you.

Many buildings have large HVAC systems to provide sufficient heating and cooling. They are important for air circulation but there is a downside to using them. This is the fact that they can be very noisy. The noise can be a big problem in some areas. Luckily, there is a solution. It is possible to create and install an inline silencer to tackle the noise.

Is it too loud?

Every HVAC system will generate some noise. Many systems won’t be overly loud and the noise will remain at a safe decibel. However, if the noise exceeds 70dB it can become very harmful.

The level of noise will depend on a number of factors. For example, the type and size of fan, length of ducts, and location will all have an impact. The size of the room and its acoustics matter too.

To get an accurate reading of the noise, you will need a dB metre. You should turn the fan on and then test the decibel level in front of the air flow.

Silencing

There are a number of ways to reduce the noise from an inline fan. The best option is to choose a suitable silencer. This can fit into the duct and then dampen the noise. It will do this by utilising sound absorption material. The silencers can come in various shapes and sizes so they suit all kinds of systems. We design bespoke ones at Ventx to give our clients the best solutions.

Other options you can try to reduce the sound include:

• Soundproofing the whole room
• Insulating the ducts as well as the fan
• Muffle the vents
• Choose a speed controller so you can limit the fan’s rotation

Talk to us if you need an inline silencer

If you have a noisy HVAC system, regardless of the type of property, you can rely on us. We have a lot of experience at Ventx and design products for all kinds of needs. Our goal is to ensure every client is happy.

So, if you need help with an inline fan, please contact us.

It is no good just leaving industrial noise pollution to run rampant. This form of noise can come from many sources, including a gas vent. What you need is a silencer that can reduce the amount of sound from these vents. Our team can assist you with this by using our modern software to create an effective solution.

Noise reduction is not only about protecting workers inside industrial facilities. It is also about following the law. One of the most important laws is the Noise and Statutory Nuisance Act. A person’s rights with this Act work in tandem with the Noise Act 1996 and Environmental Protection Act 1990. It can assist those looking to make complaints about large amounts of noise influencing their lives.

Numerous elements of the 1993 Act are similar to those found in the 1996 Act. This is in relation to the power courts hold to produce fines in addition to other punishments. There are places where they differ somewhat. One is where the Environment Health Department decides whether the sound levels constitute a statutory nuisance or not.

Statutory nuisances

So what actually are these nuisances? According to the legislation, the sound that is the source of someone’s complaint has to be detrimental. This is to their health. Alternatively, or at the same time, it has to interfere with someone’s enjoyment on their own land.

What to do?

There are those who will want to immediately complain to their local authority. However, another possibility can be to get in touch with those creating the noise. You can discuss the issues with them. This way, you can try to come to an understanding. In the case of an industrial facility, they may be able to install a silencer to limit the noise.

Let us design a silencer for your gas vent

At Ventx, we work on behalf of numerous clients in many industries. They all require their own specific model of silencer. Each one has a different design, but they are all effective at reducing noise.

If you are having trouble with a gas vent and need a silencer, don’t hesitate to contact us. We can design the perfect solution for you.

Our team goes out of its way to help clients to tackle noise pollution in their industrial environments. To do this, we make use of acoustic modelling software to create the best silencers. Designs can include the discharge silencer as well as various other options. Noise won’t be as much of an issue with our help.

The rotary blower discharge silencers are among the most critical elements if you want high performance. This is within every blower system.

The majority of people think that the discharge does not produce much sound. They are comparing it to the inlet when they think this. However, it is not true. The high frequency pulsations and discharge sound are recurrent at the outlet. In addition, they can cause the destruction of systems. These are ones working under very high discharge velocities and pressures. The reason for this is that the components tend to be within a closed system.

Minimising the high frequencies

There are many benefits to using silencers in these situations. To begin with, high frequency air flow leads to a great deal of vibration and noise. These can be annoying to those in the surrounding areas. The primary job of the silencer is to minimise these high frequencies. They do so by harmonising the pressure surges of the gas that exits the outlet to the open.

Additionally, silencers work to enhance the efficiency and accuracy of the system. The vibration and noises that occur where you don’t use silencers is a result of the air that passes through a medium. In the process, this typically cools down, resulting in medium imbalances. If you used the medium without it moving through a silencer, inaccuracy problems would pop up. However, you can use rotary blower discharge silencers to resolve this.

Ordering a discharge silencer

At Ventx, we work with a very big list of clients. Thanks to our hard work, we can design the silencers that suit their needs. As a result, countless individuals can benefit from a reduction in noise levels.

If you require a discharge silencer, or something similar, please give us a call. The products we offer are reliable and long lasting. We will also offer advice about upkeep.

Having to deal with loud noises is not only annoying but harmful too. Hearing impairment is just one potential side effect. There are many other physical symptoms that you can experience. Fortunately, we have a solution. This would be to use one of our silencers, like the discharge vent model for instance.

There are countless individuals out there with hearing loss issues. This might have been caused by leisure activities. More likely, it could have been due to a noisy workplace. The root cause of hearing loss can initially seem straightforward. However, noise-induced hearing loss has several misconceptions surrounding it. We are here to take a closer look.

Noticing a problem

Some believe that this hearing loss is noticeable immediately. It is true that numerous people suffer temporary hearing loss following a concert or loud party. However, a damaged ear is something that you may not notice right away. In fact, it could be a problem you only notice in the future when someone points it out.

It only happens with regular exposure

Another misconception is that the hearing loss only happens if you expose yourself to loud sounds regularly. One single exposure to a sudden loud noise is all it takes to cause hearing loss. As a result, it is vital to have hearing protection. An industrial silencer can help to reduce sounds at the source too.

Industrial noise

Last but not least, there are those who believe that it is only loud music that causes hearing loss. If you are an industrial worker, your profession can be as dangerous as your hobbies. In fact, industrial noise stands as one of the leading causes of hearing loss. This is one of the many reasons why people install silencers in these environments.

A bespoke silencer for your discharge vent

At Ventx, we design our products to keep people safe from the dangers of loud noises. We can create a myriad of models to suit any kinds of needs. For example, we have options for vents, fans, machinery, and more. To ensure we design the right one, we use advanced acoustic modelling software.

If you would like more information about silencers for a discharge vent, feel free to call us. We can discuss how they work as well as the kind of performance you can expect.

Part of the reason why we are so successful is because we have a long history in industrial silencer design. Thanks to our experience, we can design a blow down silencer that meets all the needs of our clients. We are capable of serving all kinds of businesses, including those who work in petro-chem, gas and oil, and other industries.

If you want the right silencer, then you need to understand what a blow down application is. We define applications of this nature as where your goal is to expel high pressure gas from a set volume. Usually, there is a final pressure and time constraint specified that is not far from the atmospheric pressure. With silencers, the most common use would be on natural gas compressor pipelines and stations.

Data requirements

For a blow down application, there are several pieces of data that you will need. The pressurised volume is one of them. Greater volumes demand bigger silencers.

You need to know what the maximum blow down time is too. Longer times allow you to use more compact silencers. In emergency scenarios, the total allowable time could be 60 or 180 seconds.

Lastly, you need to understand the final blow down pressure. You might end up specifying a final one that is under 50 psig. If you do, this shall make it hard to meet the time requirements with economic silencer selections.

When selecting your silencer, it is essential for you to use the maximum flow rate. You can’t use the average one. If you go down that route, it is going to operate at as much as 2.5 the acceptable maximum velocity for your instrument. This will be the case for the initial 35% of the blowdown cycle. This can lower the lifespan of your equipment. Therefore, you should avoid it.

Come to us for a bespoke blow down silencer

At Ventx, we understand how difficult it is to accurately predict noise. To make things easier, we employ modern computer software. This lets us create a model of the noise level that is likely to come from your facility. With the right information, we can create a suitable solution.

If you require a blow down silencer, don’t hesitate to contact us. We would love to help you to reduce noise on your site.

One of the most effective strategies for managing noise is to use silencers. Our company has specialised in designing them for several years. We strive to meet all of our clients’ requirements by creating the finest models. This includes the useful blow off silencer. By working with us to design the right equipment, you can improve performance as well as efficiency.

Industrial silencers should be able to do their duty continuously within their environment. They should offer free, predicable performance. To ensure this happens, we ensure a professional examines every model we make to check the quality. Then all it takes is the correct installation and suitable maintenance to ensure you will have many great years of service.

Handling

One area where you need to take a great deal of care is with how you handle the silencer. You should only lift it using the mounting supports or lifting eyes. Only personnel with sufficient training should make the lifting decisions.

Putting silencers into storage

Some people will only use their silencer periodically. When it is not in use, storing it correctly is important. This is especially true if you are storing it for a long period of time. When you are doing that, you need to ensure it has the right protection. Most notably, you have to keep it safe from moisture and dirt.

If you use a tarp to cover your silencer, you can keep it dry and clean. Avoid using black plastic tarps though. This will only serve to promote condensation. It is also preferable to keep the silencers indoors when you store them. They will remain safe from the elements this way.

For silencers installed in exterior locations, you need to safeguard them against moisture. This includes snow and rain. Neither should be able to enter the silencer. Moisture is dangerous since it results in long term damage and negatively influences the silencer’s performance. You can try using rain hoods. Consider screens too to prevent debris from getting in the air stream.

Let us design your blow off silencer

At Ventx, we have more than a decade of silencer design behind us. We continue to build on this knowledge so we can offer you the most appropriate model possible. More importantly, our silencers will be practical and cost effective at the same time.

If you are looking to purchase a blow off silencer or any other model, please give us a call. We can advise you and deliver a model you can rely on.

Noise is a by-product in all sorts of settings. However, when the noises get too loud or consistent, it can have negative effects. This varies from physical and mental health problems to lower productivity and more. So, it makes sense to put measures in place to reduce noise where possible. With our natural gas silencers and other solutions, you can do exactly this.

A little about natural gas silencers

With natural gas systems, the blowdown needs to generally happen rather fast when maintenance operations are in progress on pipelines. In most cases this will create noise readings that are much higher than tolerable levels. The noise is a result of two phenomena:

1. The first of these is turbulent mixing. This is the ripping of the air when the vent gas decelerates to zero velocity as it discharges into the atmosphere.
2. The other is shock noise, which is the instant loss of pressure across a choked flow device.

However, a silencer can help with the issue. It will control the blowdown and the noise that it creates. The best models have a reactive-absorptive process. This offers great attenuation for all octave frequency bands.

Silencer designs

When it comes to the design and selection of natural gas silencers, it is important to keep in mind different factors which will be specific to the application. This includes blowdown time limits, which approach will be the most value for money while meeting needs, performance, and the durability you need for the environment. In addition, you may need an evaluation of natural gas flow and to look at the noise attenuation needs.

The uses for the silencers includes combustion boilers as well as nuclear and chemical plants. In addition to this, pipelines, and petrochemical and process plants rely on them.

The thing to keep in mind about vents is all it takes is for the pressure to be a little higher than atmospheric to cause loud noises. If this happens the sound can seriously harm people on the site. The loudest sounds will also disturb nearby residents, businesses, and wildlife. The solution is to design and install the right air vent silencer.

Two parts

The best silencers generally come in two parts. The first is an inlet diffuser. What this does is it provides back pressure and reduces the flow though the silencer. It can also provide some helpful attenuation.

The second part of the silencer is the absorptive pack. This is a component with perforated steel panels. The holes allow sound waves to filter though. Behind the panels will be some form of porous material that will absorb these waves. Typical substances people favour include glass fibre or rock wool.

Importance

Many people think the inlet diffuser is the least important part of the silencer. Truthfully, some models don’t even have one. However, this can be the wrong design choice. If you don’t include one, the absorptive pack generally needs to be larger so it can provide the attenuation. If size is an issue, it is better to include the diffuser.

To get the best level of noise reduction, you must have the right perforations in the steel panels. Most importantly they must be the correct size. In addition, it is vital you choose the most appropriate sound absorption material. It is a good idea to consider all the options here and select the right one for your needs.

On top of this, the silencer must have the right flow passage arrangement. A poor design may put obstacles in the way of the flow. This can result in even more noise. Some people look to avoid back pressure. However, if you choose it properly it can be very useful. Most importantly, it can allow you to use a smaller silencer. It can also reduce the flow velocity.

Designing your air vent silencer

At Ventx we know that working closely with clients is essential to producing the right equipment for them. We do just that, getting to know as much as we can about their needs. Then we can use our cutting edge design software to model a silencer that will tick all the right boxes.

To combat loud noises, you need silencers capable of doing the job. Not just any model will do. You need one specifically for your systems. We design steam vent silencer models and other styles. To do so, we use state of the art acoustic modelling software. Every single one we create is bespoke to suit the client’s needs. As a result, you will have a much easier time controlling the noise on your site.

Many vent silencers are individually designed to abolish noise. Said noises originate from the atmospheric discharges of steam and high pressure gases. You can use a silencer to lower this. What happens is that you install a silencer within the discharge line. Alternatively, it can be at the end of this line. It supplies you with noise limitation while releasing steam or gas.

Getting the most from your steam vent silencer

There is a way to get the most out of these silencers too. What you must do is design them so that they use two noise limiting techniques concurrently. These would be reactive and absorptive. In addition, it is preferable to have sound absorbing materials. This is as well as tuned reactive chambers.

Broadband attenuation

The silencer’s absorptive behaviour supplies users with broadband attenuation. Reactive behaviours are dictated by a mixture of changes in forced phase shifts as well as flow section. It offers you greater attenuation within the lower octave bands. Each technique makes contributions to greater noise reduction. This is over the whole audible frequency range.

Noise and gases enter the silencer via compact holes within a diffuser. This provides a weighting-shift that goes towards high frequencies. In addition, a successive expansion chamber offers reactive limiting of the low frequency elements of noise. Acoustic lining that goes to the expansion chamber manages the absorption of high frequency energy. Partially silenced noise and gases head through to multi tubular acoustic models next. Here, there is one last reduction.

Industrial settings can be incredibly noisy. This is largely due to the heavy machinery and systems in use on the sites. Repeat exposure to the loud noises can cause hearing damage and several other health problems in people who work on the site or live near it. To make sites safer, it is important to reduce the noise to a less harmful level. The best way to do this is with industrial silencers.

The key to maximising sound reduction is using the right silencer in the right location. To do this, you need to know about the different types you can choose from. Below we will have a look at four styles.

Absorptive

This is probably the most common type of silencer on the market. The style is very popular because they actually feature materials to absorb the sound energy and turn it into heat. The absorptive material can vary in type and thickness to suit different needs. These silencers are very dynamic because you can install them horizontally or vertically in an array of settings.

Reflective

The second style of silencer does not seek to absorb the sound waves. Instead they reflect it back towards the source to reduce the amount of noise that escapes. These silencers can be very small because they don’t need to contain any absorptive material. They are also easy to clean, making them a low maintenance option.

Steam vent or gas

These models generally don’t seek to absorb the sound or reflect it back. Instead, they look to diffuse the flow of pressurised gases or steam. The high flow and velocity can result in very loud noises. However, this kind of silencer can reduce the pressure and allow gas or steam to diffuse to the atmosphere at a lower velocity.

Combination

As you can probably guess from the name, this type of silencer can combine different elements of various models. Most commonly they are absorptive and reflective to provide the benefits of both.

One of the worst things people have to put up with is noise pollution. To avoid the numerous health issues it produces, the industrial silencer was born. These devices can substantially reduce the amount of noise. With our instruments, you can manage the noises coming from all sorts of machines, HVAC systems, and more.

A growing concern

In the world of busy cities and towns, as well as hectic living, noise pollution is becoming more of an issue. The dense traffic does not help matters either. This issue does not produce as many huge health issues as other types of pollution. However, they still exist regardless. They include high blood pressure and loss of hearing. There can also be behavioural and emotional issues, including anxiety and aggression. Knowing this, it becomes evident that noise prevention and pollution control are vital.

Regulations

The Control of Noise at Work Regulations 2005 aids us in safeguarding the UK workers that encounter noise pollution. This could harm their hearing. Noise pollution that happens at work can lead to tinnitus and deafness in many UK residents. It can also cause other ear conditions too.

Under the laws, employers must inform workers in loud locations about the dangers to their hearing. They have to then train someone to introduce a noise programme. Moreover, they have to perform frequent noise assessments. Weekly or daily average exposure could surpass 85 dB(A). If this happens, they must designate the area as a hearing-protection zone. Finally, they must provide suitable PPE.

Technology

Aside from the law, technology can play a part in lowering noise pollution. One solution would be moving traffic from residential locales. Another is installing noise barriers at major roads to deal with the sounds. The design of buildings has taken noise into account too. Many are now built to contain it. Not to mention, car engines are quieter than they once were.

Then there are the industrial sites. We assist clients here by providing brilliant silencers to keep people safe.

Ventx is one of the most skilful designers of silencing products in the UK. We can offer solutions for various needs. This includes models for vents, fans, and all kinds of systems. We are also the best place to look for a bespoke safety valve silencer. Every product we offer will be fit for purpose because we put a huge amount of effort into getting the designs right.

Few components are as important as safety valves. They are the final line of defence in systems that rely on pressure. The idea is, if the pressures in the system rise too much, the operator can open the valve to release it. This can help to prevent total failure, something which could put lives and the property at risk.

How do they work?

Safety valves usually have a spring and back pressure to keep them closed. They therefore remain in equilibrium until the system pressure rises to exceed this. When that happens, the valve can open. As a result it helps to reduce the build up of pressure in the system.

When a safety valve opens it could release compressed air, inert gas, steam, hot water, or even process fluids. This will hopefully bring the pressure down and prevent system failure.

The valves must be the right size to ensure the pressure can come down. If they are too small the valve will not be able to discharge the excess pressure, meaning it will continue to rise in the system. On the other hand, if they are too large, the high system pressure will not be able to open the valve entirely. This can result in a cycle of opening and closing which will create a chattering noise.

Use a safety valve silencer

While they are a potentially lifesaving component, safety valves can be very noisy when they release the pressure. As a result it is a good idea to use a silencer. This can mitigate the noise and improve safety and performance.

Ventx designs fantastic silencers that will be perfect for your needs. They can be various styles and sizes to suit different needs. This includes being able to address loud discharge noises from safety valves.

Autoclaves are not a new piece of equipment. In fact, the first steam steriliser dates back to the 19th century. This was when Charles Chamberland, a French microbiologist, found the benefits of using steam instead of open flames. Since then the technique has become a standard in medical facilities, research, and more. While the machinery is useful though, it can get noisy. Luckily, Ventx is here to help and can offer an autoclave silencer to suit any needs.

What can an autoclave do?

There are lots of uses for autoclaves. They are the best for applications that require sterilisation as the hot, high pressure steam can kill micro-organisms like bacteria and viruses. As a result they reduce the risk of infection and illness.

The most common uses for autoclaves are medical, including in the creation of pharmaceuticals, sterilisation of medical instruments, dentistry, and the manufacture of prosthetics. However, they also have use in the veterinarian field, tattooing, and all sorts of labs. In addition, they are good for sterilising medical waste before disposal.

The machines can come in a variety of sizes, from large ones with huge capacities to smaller units. The difference is usually down to the capacity. The largest models can be hundreds of litres whereas small ones can be less than 100.

Noise

The thing to keep in mind with autoclaves is that they can be noisy. The steam is very hot and at a high pressure. As a result it can cause noise issues, especially with valves and vents.

There are many cases where the noise from an autoclave is a bad idea. For example it could be a sensitive lab where the sound would disturb people and affect tests or research. Or, it could be a dentists or a clinic where the sounds would affect patients. Whatever the case, reducing the sound is a good idea.

Choose the right autoclave silencer

At Ventx we are confident we can design silencers to suit all kinds of autoclaves. Our team have a lot of experience and access to great equipment, including modern modelling software. As a result we can deliver the most suitable products.

If you want to talk to us about autoclaves or need to create a bespoke autoclave silencer, please get in touch. We can give you the best service as well as exceptional support.

Heating and providing hot water in large industrial buildings can be very challenging. Standard boilers may not be up to the challenge, especially if there are lots of radiators and facilities. A great option here is to use a steam boiler. However, using them can cause noise that could become an issue. The solution is to choose a reliable steam boiler silencer.

Complexity

Steam boilers are pretty complex, especially in comparison to general gas, oil or electric models. There are two types – shell and water tube. The first has the hot steam flowing through pipes, heating water around them. The latter on the other hand is the opposite and has the water flowing through tubes with hot steam around them. Water tube models can achieve a higher pressure. Shell boilers can produce a huge amount of steam every hour.

Both models can effectively provide hot water and heat for larger buildings. This is because steam can travel more easily through large pipes than water. It can also reduce the amount of pumps the boiler needs.

These boilers can last a long time, especially with good maintenance. However, they can be noisy. One important feature is the blowdown. This enables the removal of dirt and sludge from the system. When the valve opens it can be noisy though. The system can also generate noise because of the steam, especially venting it.

Steam boiler silencers

If the noise from the boiler is causing issues, you can choose a silencer to dampen it. Ventx can help here, offering a reliable service every time. We design bespoke models to suit each specific system we are working with. That means we can offer the most appropriate solution rather than trying to make a standard model work. The end result is better performance and efficiency.

You can contact us if you have any questions about steam boiler silencers. We can cater for all types of model and any size. In addition, we can provide ongoing support once the silencer is in place.

If you are having problems with noise, our company has what you need. Industrial silencer design is our speciality. We use our skills to find solutions that will benefit clients. Since loud sounds can impact you in many ways, it will be worth your time to see what we can offer.

Loud sounds may not directly appear to influence how we feel. However, with daily exposure, gradual effects can start to set in. Such exposure is common in industrial settings. The following are some of the most substantial long-term health problems people may experience due to industrial noise.

Hearing damage

We will cover the obvious one first, which is hearing loss. The ear is a sensitive array of compact structures. They work to focus and translate sound waves to your brain. Sound moves inside your ear canal. It then vibrates the eardrum and leads to three small bones vibrating. The cochlear hairs notice this and alter the vibration. It transforms into an electrical signal that’s for your brain.

Workplaces where there are 85 decibels of unending noise are putting their employees at risk. Ears won’t have the opportunity to heal from temporary hearing loss. What’s more, cochlear hair cells will die eventually. This restricts the level of sound your ears can pass to the brain, leading to irreversible hearing loss.

The cardiovascular system

Another issue would be cardiovascular impairment. Frequent exposure to loud industrial noise can cause this. Loud sounds are often a signal to turn your fight-or-flight response on. Since this is the case, daily exposure begins this activation. Since this is the case, it can place stress on a fast-beating heart.

Stress

The most important thing to keep in mind is that noise is a stressor. Loud industrial noise can stimulate the nervous system and cause the release of hormones that cause stress. People can struggle with several illnesses linked to too much stress. It can also affect concentration, make people feel tired, and affect the mood.

Industrial silencer design

At Ventx, to create the perfect products, we use state of the art acoustic modelling software. With it, we analyse your systems and decide on the ideal silencer design. This is one that won’t compromise your own systems. However, it will effectively reduce the sound to a safer level.

If you would like more information about industrial silencer design, feel free to contact us. We have a wealth of experience so we can assist clients in all kinds of noisy industries.

The noises that come from industrial facilities can cause an array of issues. Firstly, the sound can affect people on site. This could harm their health, wellbeing, and performance. Secondly, the sounds can disturb people nearby, whether it is homes or other businesses. Thirdly, the issue can harm wildlife in the area. With all of this in mind, it is important to have a serious look at industrial noise reduction.

There are a number of different ways for facilities to reduce noise. Ventx has a lot of knowledge of many of them as a leading producer of silencers. We want to take a quick look at some of the top methods you can use.

Damping

One of the things you can do is install damping to help improve the soundproofing. You can install materials on walls, floors, ceilings, chutes, tanks, panels, and more. The goal here is to make it harder for noise to escape as well as reduce the volume of the noises that do.

Fans

You have a number of options to reduce the noise that comes from loud fans. For example there are different silencers to choose from. You can also change the layout to remove anything that might disturb the airflow and cause noise. It may be a good idea to ensure the fans can work at their peak as well.

Ductwork

Ducts can be very noisy and also create an issue because there needs to be openings to install them. This can allow more sound to escape from the facility. What you need to do is fit silencers to the ductwork and seal it, especially around openings in walls and other surfaces. Both of these can block noises.

Pneumatic exhausts

Noise from these can be really loud. Luckily you can fit silencers to reduce it dramatically. You can choose a silencer to deal with noise from back pressure as well as the release of air.

There are many other things you can also do to reduce noise. This includes replacing pneumatic nozzles for quieter ones, getting quiet modern motors, and changing chain and timing belts.
