Ventx Ltd

When your ventilation systems become overly noisy, you will want to tackle the issue as soon as possible. Failing to do so can result in big problems for anyone on the site, including physical and psychological damage. What you need to do is choose one of our vent silencer designs. We create these products to dampen the noise from HVAC systems and bring it down to safer levels.

A well-designed HVAC system is one that should not come with unpleasant noise. Typically, problems like whistling and rattling noises aren’t major problems. However, extremely loud air vent sounds will be very disruptive.

The two most common reasons behind loud HVAC sounds are too short of a return air duct and high air velocity. The latter is often the result of a bad design where the ducts are too narrow or not long enough. Both will lead to an efficient transmission of fan noise via the return air duct.

You may have heard about solutions to deal with the noise. However, you should know that there are certain things you can’t do when tackling the issues. Read on to find out what they are.

What can’t I do?

Firstly, you should not try to lower the fan speed via modification. Airflow is vital for HVAC systems to function. When there is not enough, the fan noise may go down, but there can be other problems. Examples include low pressure trip and freezing.

Don’t try covering the vent to minimise noise either. A HVAC set up requires return air for it to function efficiently. When there is not enough airflow, you can experience high fan motor amps and trips later on.

Finally, you cannot remove the filter to lower noise. Filters are necessary to stop dirt from gathering on the cooling coil. This is much harder to clean. When the coil is dirty, there can be low pressure drip and inadequate cooling problems.

Choose a vent silencer

If you want an effective way of dealing with noise, you should use a silencer. At Ventx, we carefully match the silencers we create to the specific application. With our acoustic modelling software, we can inspect your systems and come up with the perfect design. You will be able to carry on without worrying about noise.

So, if you would like to work with us to create a vent silencer, feel free to get in touch. We can provide the greatest results for all kinds of properties, including the noisiest industrial facilities.

People all over the world are suffering due to noise problems. You can use protective equipment to reduce the impacts, but that won’t tackle the issue. For a more permanent solution, you should use attenuators. Also known as silencers, you install them on your current systems and they minimise the noise they create. In addition to benefiting the people who come to your site, these devices can help you comply with the set UK environmental standards.

Over the years, manufacturers have generated a number of standard silencer geometries. They exist to handle the pressure drop vs insertion loss equation. There has been a huge amount of development and testing to ensure the designs will work. As a result, you can apply them on an application specific basis, ensuring you choose the right unit for your project. You will obtain the necessary acoustic performance at a rational pressure drop.

One thing to note here is the designs get labelled based on certain velocity profiles. However, you can apply them to a larger range of velocities when taking an acceptable pressure drop into account.

Low velocity

One form of silencer geometry is low velocity. You can also look at this as a high pressure drop design. The geometry supplies an extremely high level of acoustic performance. As velocities progress past 1000 FPM though, you will find pressure drop levels starting to become unsuitable for many applications.

Medium velocity

Another form is medium velocity. This is the best performing all-rounder you can find on the silencer market. Thanks to the straight through parallel entrance, there is a high degree of insertion loss. As for the tapered discharge, it works to keep the pressure drops to a minimum.

With such a model, you can work through a large number of applications ranging between 0 and 2000 FPM. There is also going to be a reasonable level of pressure drop for them all.

Speak to us to choose the right attenuators

At Ventx, we offer bespoke silencers that can work within countless facilities as well as out in the field. Thanks to our acoustic modelling software, we can design the perfect solutions for you. With them you will be able to control the noise coming from duct work, generators, compressors, and more.

So, if you need our help with attenuators, please let us know. We can get the best results for you.

The problem with noise in industrial settings is that it can cause a lot of damage. It can harm people, the wider environment, and even sensitive equipment on the site. In order to prevent this, you need to use an attenuator. Another name for these installations is silencer. Using special acoustic modelling software, we can create the perfect designs for your facilities.

Attenuators have been around for a while. However, there is still some confusion surrounding them. For people to understand just how important they are, we feel that it is necessary to discuss them in more detail. To that end, in this post we will be going over three of the questions people ask about them.

What are they?

We will start by going over what they are. In the most basic sense they are products with an inner lining of a material that can absorb sound waves. When the sound moves through the attenuator, it will get absorbed into the insulation. That reduces the noise.

One thing to note is you can’t treat these products as standard parts of a ductwork set up. Instead, through the procedure of installation, handling, and transportation, you must deal with them as specialist items. It will help you to get the best results.

What happens to the absorbed noise?

The noise that gets absorbed into the insulation in an attenuator is held and transformed into heat energy. This can then release over time. It is a safe and effective way to tackle the problem. Some designs can even make use of the heat for secondary processes.

Where to use them

Attenuators typically work best if you install them close to the source responsible for creating the noise. Often this is a fan or a motor. You are best off installing the attenuators behind your fans. They can be fundamental parts of every ventilation system, so definitely worth the investment.

Let us design your attenuator

At Ventx, we make it a point to design our products in the correct ways. Failing to do so would cause them to undermine your existing systems. No two attenuators are the same either, as each customer has their own requirements.

So, if you need our assistance with noise reduction, feel free to contact the team. We can discuss options with you, including different types of attenuator and silencer. At the end of the day we will deliver items that offer high quality results.

Since industrial noise pollution can cause so many problems, you have to tackle it before it becomes too dangerous. To do this, you need the right products. Our business excels in providing silencers that can minimise the noises from various sources. We can build an intake silencer and many other models to match your facilities.

When you use a massive gas or diesel-power four/two stroke engine or turbine, huge amounts of air get drawn into the equipment. This is so it can allow the combustion. Such air induction set ups could be aspirate naturally. Alternatively, they might use compressors or turbo chargers to augment the air pressure. This is the pressure that feeds into the cylinders or air mixing chambers to amplify performance or efficiency.

Air speed and rotation noises

The speed at which air enters the system can produce massive amounts of noise. Furthermore, the compressor’s or turbo charger’s high rotating speed can make sound radiate down the induction pipe. From there, it can go through the intake filter and out into the atmosphere. This is especially noticeable on incredibly huge rotating induction systems. Noise levels here can surpass 120 dB within the greater 2000 to 4000 Hz frequencies.

The central pod

Something else the design has is a central pod, which partly obscures the line of sight. This tackles the flow velocity noise linked with the great levels of cool air needed to feed every form of internal combustion engine. It is the same with blowers of all configurations and sizes, as well as boilers and small gas turbines.

With some modifications, you can use a silencer on low pressure gas, air, or steam pipelines. Here, noise radiation could be evident. Under moderately different circumstances, you can also use a silencer for medium to high velocity air discharge and exhaust applications. You just have to make sure you get a suitable model to fit the system.

Talk to us to design your own intake silencer

At Ventx, we are careful when we design our silencers for clients. It is necessary to match our utensils with the specific application. With the acoustic modelling software we use, this is simple. It also ensures we can provide the very best results.

We support clients across the UK from an array of industries, including oil and gas, chemicals processing, manufacturing, and more. Many of them rely on huge noisy engines to power different equipment and systems. So, if you find yourself in need of an intake silencer, please let us know.

We supply high calibre industrial silencers that users can rely on. The purpose of these devices is to diminish the noise coming from various forms of equipment and machinery. These contraptions can produce a lot of sound, which can prove to be harmful in various ways. However, with our in-line silencer products, we well as other designs, you will be able to tackle the issue and improve safety.

One design that is common in most industries is the exhaust silencer. These can fit into the exhaust systems of engines, generators, and more. They control the noise by changing the speed and direction of the exhaust gas flow. The right design can reduce the sound to a much safer level. They can also potentially improve performance as long as there is no restriction to the gas flow.

Multi-chamber silencer

A variant of the exhaust silencer is the multi-chamber model. These are utilised in most engines and are designed to manage the noise. This is while it creates suitable back pressure levels. They are models that don’t affect the performance disproportionately.

These silencers are great for naturally aspirated engines, as well as in supercharged ones. They feature numerous chambers into which gas sequentially flows prior to escaping.

Straight-through silencer

There are also straight-through silencers. They are suitable for turbocharged engines in addition to some naturally aspirated ones.

Here the silencer passes gas through the silencer’s centre in a straight line with no deviation. Therefore, the exhaust gas does not have any kind of restriction that could cause turbulence. Due to the effect of a quick gas discharge, the performance is better. At the same time, the noise levels will fall.

Speak to us for an in-line silencer for an exhaust system

At Ventx, we are careful when we match our silencers to each specific application. To get the right results, we use acoustic modelling software. With it, we analyse systems and use the information to design and produce the ideal silencer. This is how we deliver the most reliable products.

We are the top supplier of in-line silencer solutions in the UK. So, if you would like us to help you with noise problems, please let us know.

High noise levels affect us in various negative ways. There are physical and mental responses that can impact our lives. In order to prevent this, you need to keep the sounds at your facilities to an acceptable level. The best way to do it is with one of our silencers. We provide various designs, like inline silencers, so we can silence an array of equipment and systems.

Noise can come from all kinds of sources, including inline fans. However, we don’t always know specifically why irregular levels are occurring. In this post, it is our intention to explain why these fans can become noisier than they should be.

Vortex shedding

The first cause we will go over is vortex shedding. It is a broad band sound that is produced via air separation from the trailing edge and blade surface. You are able to control it to a degree by having a decent blade profile design. Having serrated or notched trailing blade edges, and proper pitch angle will help as well.

Turbulence

Another reason for the noise could be turbulence. It happens in the actual airflow stream and can produce the broad band noise. Sharp bends and edges, as well as outlet and inlet disturbances, shall lead to more turbulent airflows.

Speed

Speed is also a massive contributor to fan noise. Let’s say for example that you lower the speed of your fan by 20%. The decibel level is going to fall by 5 dB. It is important to maximise fan efficiency rather than just increasing the speed and rotation.

Load

We need to talk about fan load too. The noise can vary alongside the loads. For example, a higher load can make fans much noisier. However, it varies by model. But, fans are typically quieter when you operate them close to their peak efficiency.

Inline silencers to quieten fans and more

At Ventx, we can design a silencer to reduce the noise coming from all kinds of sources. In addition to fans, we can use them to control generator, compressor, and duct work noises. All of our designs shall differ in terms of appearance and attenuation level. However, they will help you to achieve a safe level.

So, if you need any inline silencers from us, please get in touch. We can design them for almost any need, including retrofitting to very noisy facilities.

We understand how annoying industrial noise is. Our team has already been able to help countless clients who have had issues with it for one reason or another. The solution we are offering you is a silencer specifically to fit your current systems. We can provide one that can help with your gas vent, as well as others that can silence machinery. So, with our help you can reduce the sounds in and around facilities.

One area that can become rather noisy is the furnace. In a perfect world, the appliances responsible for making our buildings comfortable would function soundlessly and smoothly. However, they can make plenty of noise. For anyone with concerns that their furnace is too loud, it is best to figure out the source of the sounds. You must also determine whether it is normal or not.

Is it banging?

Furnace banging is definitely something you will want to listen out for. Should you hear a loud bang when you turn the appliance on, there may be an ignition issue.

Once a furnace receives a signal from the thermostat to start a cycle, the gas valve opens. The pilot light or ignition system should immediately ignite the gas. However, when this system malfunctions, a small degree of gas can accumulate in the combustion chamber. When ignition happens, there is typically sufficient gas build up in the chamber to create a banging sound. This noise can move through the building via the ducts.

What can affect the gas ignition?

There are a number of things that can influence gas ignition within a furnace. If you have a pilot light, a weak flame could stop the gas from rapidly igniting. Furnaces with an electronic ignition may have a problem with the set up. Furthermore, the burners can be clogged or dirty.

Another possibility is that the gas pressure could be so low that ignition doesn’t occur. This is until there is a substantial build up within the chamber. Any issue with your furnace needs to be inspected by a professional.

Talk to us for a gas vent silencer

At Ventx, there are important reasons why we use silencers to deal with industrial noise. There are the obvious hearing impairments. However, there can also be mental health complications. Some examples are higher stress levels, fatigue, and anxiety. By installing our silencers in places with excess noise through, you can manage it far more efficiently.

So, if you need a silencer for a gas vent, HVAC system, or any other noise source, please let us know. We are confident we can create the most effective product for you.

Industrial noise pollution is an ongoing concern we have been fighting for a long time. To do so, we produce special tools known as silencers. They work with your equipment to drastically lower the sound levels they produce. You can choose them to fit with existing systems or for brand new facilities. We can offer you discharge silencer designs as well as many other models.

Exposing yourself to noise in a laboratory can lead to irreparable hearing damage. Many sections of the facility can become loud due to the equipment you use. Wet vacuum systems, centrifuges, and high-pressure air cleaning all produce concerning amounts of sound. However, after you pinpoint the risk, Noise Induced Hearing Loss (NIHL) can be prevented. The tips we have below will help you to do that.

Minimise

There are several ways to minimise the sound, including building enclosures around noisy equipment. However, if you find enclosure to be unrealistic, you can look at other measures. This can include mufflers or acoustic screens. It can also include panels and lining guards with noise-reducing material, or vibration isolation systems. One of the best options without question though would be to attach silencers to your exhaust systems.

Reposition the equipment

Repositioning could be something else you can try. Think about the room itself in which you place your gear. Consider where it is going to sit in relation to the environment. For instance, a reflective, hard exterior shall enhance the noise from loud machinery. It will do so by around 3dB for every large exterior. You can move the equipment to another part of the space where this won’t happen.

Maintain

Keeping all of your equipment inside the lab and maintaining it correctly will help you lower rattles. Additionally, such action will minimise the sounds that occur as part of the wear and tear of your gear. The last thing you should do is wait for something to go wrong. Have the experts do some maintenance and checks when you notice any increase in sound or new noises.

Let us design your discharge silencer

At Ventx, we use acoustic modelling software to ensure that every client is given the correct silencer. By analysing your systems, we are able to design and manufacture the ideal item for your setting and the inhabitants. With one of our silencers at your disposal, you will have all that you need to keep your noise levels in check.

So, feel free to give us a call if you have a noisy lab to deal with. We can look at creating a discharge silencer or another model to tackle the sound.

Industrial noise is a problem you have to tackle at the source as soon as you notice it. The source in question could be one of many things. One example is a discharge vent. If this is the situation you are in, we can manufacture a silencer that can work wonders for you. Using our acoustic modelling software, we will be able to design something that fits in perfectly with your systems and equipment.

With heating and A/C vents, you should expect some noise. Popping sounds for instance are entirely natural. They occur during a shift of hot or cold air through your property. When you are warming the building, your ductwork is going to expand from the hot air. With cold air, the opposite happens. The popping is your ducts starting to shift to meet the temperature requirements.

However, if you have particularly noisy heat vents or A/C systems that make other noises, something is probably wrong. It may also be due to the design of your ducts.

One shape is louder than the other

The model of duct you have in your property might be producing more sounds. Shape is one of the biggest influences of duct noise levels. Ducts come in a multitude of shapes, including rectangular, square, and round. The last is the quietest, with rectangular being the loudest. The angular corners are the cause because they create more air turbulence.

Gauge ratings

These can influence the noise too. If you have metal ducts, then the material utilised to make them will have a gauge rating. When the scores are lower, the metals will be stronger and thicker. Consequently, your ducts will have a lower chance of popping and expanding. When there is more popping than usual, the metal may be thinner and weaker.

If you have especially noisy vents that are causing issues, you can use one of our silencers. They will lower the noise to acceptable levels.

Silencing each discharge vent

At Ventx, our silencers allow you to manage the noise that comes from all kinds of sources. In addition to the discharge vent, examples include fans, generators, and compressors. These devices will benefit everyone who enters and spends time in your property. Not to mention, they will allow you to follow the UK environmental standards.

So, if you need one of our silencers, please don’t hesitate to ask.

Taking on noise pollution alone is difficult without the right utensils. Thankfully, our business provides a readily available source of silencing tools. What we do is supply a wide array of silencers to suit most needs. This includes designs like the blow down silencer. Each one is tailored to our clients’ requirements so they will be appropriate for your particular facilities.

One of the leading working environment problems is noise. It is something that can negatively impact our mental and physical wellbeing. In the worst case scenario, there will be permanent damage. How employees are influenced by it depends on the time the person is exposed to the sound and the level.

Blowing with compressed air

A main source of noise in industry settings is blowing with compressed air. When you do this, it is essential that you utilise the right gear. It is especially important when you do it manually with an air blow gun. The operator is going to be right near the noise source here, so the risk is very high. Air nozzles and air blow guns normally produce sound levels over the acceptable limit on 8-hour work days.

Noise is produced when your compressed air expands out of your set up. It produces turbulence as it moves. To impede the sound, you have to minimise and control the latter.

Another fact to note here is that having a high noise level does not mean there is a decent blowing force. This is an out of date misconception. Thanks to newer technologies, you can combine a strong force with a low sound level. You just need the right equipment.

In the majority of instances when blowing using compressed air, you can minimise the sound level by around 10 decibels with a silencer. Ears perceive this as halving the noise level. This makes a substantial difference in relation to the risk of injuries.

Talk to us for a blow down silencer and other equipment

At Ventx, we use acoustic modelling software to match our silencers to the relevant application. We analyse your systems in order to design and construct the perfect product. That means there is a simple installation and maximum benefits.

So, when you need a blow down silencer, you will receive one that will work correctly if you come to us. Please let us know if you want to talk about your needs.

Loud noises are troublesome to say the least. Not only are they distracting, but they can result in several health problems. We aim to prevent these issues by offering first rate silencers. Our team can provide you with the finest blow off silencer design there is or a model to suit almost any other need. With our help, you will have a much more pleasant experience while you are at work.

Something we often see is confusion about blow off and bypass valves. They may have similar names, but there are several differences between the two. What we are going to do is talk a little about both to help you understand them better.

Blow off valves

Traditionally, these devices vent 100% to the atmosphere. This is the source of the “pssssh” sound. You can find them in a huge array of systems in different facilities. For example, they are common on turbines and natural gas pipe lines. They work to rapidly reduce pressure to ensure a failure does not happen. Some operators also use them to keep operating conditions consistent.

The bypass valves

This valve design differs from the blow off one since it does not vent air to the atmosphere. Instead, it operates by redirecting part of the gas into an intake or reservoir. As a result, it can reduce the pressure. With this design, the pressure is considerably more consistent. It can also avoid the noise of venting.

Speak to us if you need a blow off silencer

At Ventx, we know that our industrial silencers aren’t your normal everyday items. However, we work hard to ensure you have one that can solve your problems. Since we use acoustic modelling software, we can match our products to your facility. So, they can focus on your specific operations to provide silencing that works for you.

If you find yourself in need of a blow off silencer, feel free to speak to us. We can design a product for you that will protect your employees and anyone else near the vent. It will help to keep the noise under control.

Industrial noise comes from a huge variety of sources. This includes things like generators and compressors. In addition, some forms of gas can get noisy when you transport or vent them. That is why we design and supply first class natural gas silencers. To do so, we use special software to ensure our models can incorporate into your systems.

One thing you might not be aware of is that pipelines produce noises that can negatively impact your health. Gas lines in particular produce a phenomenon of low and extra-low frequency sound waves. They occur due to the transmission of high pressure natural gas through the set ups. These noises are referred to as flutter and hum.

What is flutter?

This is a persistent pulsating airborne pressure wave. It radiates from pipelines. It is a problem that affects the immediate area. You will find that it sounds like the rumbling you can hear from distant thunder. It also feels like the pulsations originating from a helicopter that is flying in the distance.

The big issue is the sound can penetrate houses and feels like a vibration in your ears and head. Another place where you can feel flutter is outside as a discomfort because of interior organ resonance.

What about hum noise?

This is an invasive and persistent low frequency droning, rumbling, or humming. It is not audible to everyone. It tends to resonate in enclosed structures, causing vibrations/sounds between 1 and 50 hertz. Hum waves can move over 25 miles from their origin and expand over an area.

The hum is usually felt more than heard because it is a sputtering tonal noise. It is also an accompanying vibrotactile sensation. People often describe it like numerous intensities of idling diesel engines that are always operating outside their property. Little is known about hum, making it the more unsettling of the two.

Talk to us about natural gas silencers

At Ventx, we understand how important it is to properly design a silencer. If they are not right, they could compromise your set ups. It could lead to even more noise or even damage equipment. We make sure this does not happen though.

We are very proud to have been able to serve a long list of clients, each with their own specifications. Our approach ensures you get the attention you require. As a result, you have the right support and can expect the most effective results.

So, if you need our natural gas silencers, please let us know. We can design them for any kind of pipeline as well as other facilities in the industry.

We are experts when it comes to the topic of noise pollution. This is a problem that plagues countless industrial companies. The air vent in particular can be a noisy piece of your infrastructure. To help, we supply high calibre silencers. We design these mechanisms specifically so that they are suitable for your existing systems.

Noisy air vents are definitely annoying. However, they could also be telling you that there is trouble afoot. Hearing some noise when the HVAC system operates is normal. However, you could start to hear strange noises like grinding, squeaking, clicking, or rattling. In these situations, you will need to look into things. Read on to find out about two things that lead to noisy air vents.

Refrigerant leaks

One cause of the noise could be a leaking refrigerant line. When these lines leak, they cause bubbling and hissing noises. They can easily travel through the ducts and out of air vents.

Another fact is that these noises often link to compressor problems and valve leaks. Whatever the situation, these can be dangerous complications. As a result, it is not wise to try resolving the problem on your own. If you hear bubbling or hissing coming from your air vent, turn the system off and talk to an expert.

Trouble with the electronics

There could also be electrical control problems. Something you may notice when your air comes on and shuts off is a click. This is a normal sound. When there is constant clicking though, there might be complications with the electrical control on your thermostat. Furthermore, there may be a system relay disruption. Replacing an old relay switch consists of handling wires carefully on the new and old relays.

If you have neither of these issues and the vents are still noisy, you will probably need a silencer. We can help you design the right one.

Reliable equipment for every kind of air vent

At Ventx, we combat the necessary evil that is noise pollution by designing the best industrial silencers. With one at your disposal, you can control the noise coming from a wide variety of sources. In addition to vents, they can help you with generators, compressors, and more.

So, if you would like to know more about our silencers, feel free to contact us. We can create a solution for any need, supporting clients who have to address noise from an air vent as well as people designing new facilities.

Industrial silencers aren’t something you see every day. When they do make an appearance though, it is always for a very good reason. You can use these tools to reduce noise coming from all kinds of sources. This includes a steam vent. The team will design something that fits in with the systems to reduce the sound and the harm it can cause.

When water gets to a temperature surpassing 212ºF, it starts becoming steam. In industrial settings, experts can use steam for a number of things, including heating and sterilisation. With the right system they can control the distribution of the steam. However, several things are going to happen here that can produce huge noise levels.

Higher temperatures

One thing that can happen is the steam becoming lighter when the temperature climbs. This can result in greater noise levels. So, you need to control the temperatures.

Flow

Something else that will lead to the noise increasing is a high mass flow. If there are any openings in your valves, they can increase it.

Also, the upstream pressure could be considerably louder than the downstream pressure. Here, the noise can hit much louder volumes too.

Increases in safety regulations

Contemporary industrial settings have to deal with increases in safety regulations. This is to save workers from injury because of workplace dangers. Noise is one of the areas where the regulations are now quite strict.

You need to address every source of noise in industrial settings. This includes steam vents. If the sound levels are too high, it can damage the hearing of the workers. Distractions due to the noises can cause other problems too.

It is here where we introduce steam vent silencers. They can lower noise to a point where it is safe for human ears. We can design them to address the specific level of noise, whether it is from continuous or emergency venting. Either way, the silencer will be there to help.

Multiple factors shall dictate your silencer’s application here. This includes how much attenuation is necessary as well as the allowable pressure drop. We will consider all of these factors to give you the best equipment.

Speak to us about steam vent silencing

At Ventx, we do everything in our power to ensure that clients receive the most suitable silencers. We have acoustic modelling software we can use to match each design to the particular application. This will maximise safety and also ensure you will be complying with the UK environmental standards.

So, if you need our help to tackle steam vent noise, feel free to contact us. We work in any industry, utilising our extensive knowledge and experience.

We are specialist designers of industrial silencers, able to support clients in all kinds of noisy industries. Our team works hard to ensure that clients have the tools they need to tackle their noise problems. It could be sound from a particular machine or piece of equipment, or a specific system or pipeline. In any case, we work to offer bespoke products that are safe as well as effective.

With the topic of noise, dB (decibels) is an important form of measurement. However, people often confuse it with dBA. They are not the same and you can’t use them interchangeably. To prevent any confusion, we are going to offer an explanation of both in this post.

Decibels

The dB is what we use for decibel. As you may already know, it is a unit of sound measurement. What this specific unit measures is the strength of a signal or the loudness of a sound. It is computed as the signal to noise ratio.

We do commonly use dB whilst referring to measuring sound. But, humans are not able to hear each frequency equally. Due to this fact, those sound levels belonging to the low frequency end of the spectrum are lower. The human ear is more sensitive at high audio frequencies and less so at low ones.

Accounting for the frequencies

For you to account for this detail, it is necessary to produce different weightings. This is so you can provide a loudness measurement that factors in how our human ears can perceive sound. The most common weighting in many areas is “A”. Values you correct with this weighting system are in units of dBA.

So, when there are values that aren’t corrected to account for human hearing, we write them using dB. However, if you see them as dBA you can tell they factor in the A frequency. Hopefully this clears up any confusion surrounding the two units.

These aren’t your everyday utensils; we design them to be bespoke for maximum benefits. So, when you do need one, you can rest easy knowing you can get the perfect solution with us.

Noise in the industrial sector is a problem that is sadly increasing. This is the case for employees and those residing close to noisy businesses. The noises can spoil what was once a healthy work environment. As a result, guidelines exist that dictate the level of sound you can expose people to at work. In this post, we want to discuss two things you can do to keep the levels down.

Operating times

To begin with, you should not operate your loud machinery for longer than the time the manufacturer recommends. Adhere to the guidelines they give you as exceeding them can cause excessive noise. This often happens because the equipment starts to suffer under excess strain or due to heat.

You should also measure the noise and map it. Figure out where and when it is going to be an issue through the use of sound level meters. Utilise them over a period of time so you can get a clear idea of how it changes over the day. It will help you to improve awareness about noise in the workplace.

Is there somewhere else you can work?

Another smart decision would be to move noisy projects elsewhere. Use different spots in the workplace for separate tasks. You should have the noisiest ones away from your primary work area if you can.

You can also try isolating the noise. Move your gear to a soundproof area if you have one. If not, you can try using sound proofing materials to create one. Alternatively, you can use sound enclosures to isolate individual noisy pieces of equipment. This means you can leave them where they are but still dampen the noise.

Speak to us to design an industrial silencer

At Ventx, we use acoustic modelling software to match our silencers to the specific application. This is important because the last thing we want to do is compromise the systems or equipment you already have. Our aim is actually to make them more efficient if possible.

Steam boilers are a popular choice for a huge array of industrial facilities. They can be used to provide power, heating, or to produce steam for various uses. However, there is an inherent risk here because the pressure can vary. If you are not careful, it could build to such a level that the boiler explodes. Luckily, there are ways to prevent this. The most reliable is to use safety valves. However, that can also mean you need to invest in a safety valve silencer too. Below we will look at why.

Over pressure conditions

The pressure of the steam in a boiler can increase for a number of reasons. Some of the most common include electrical power failure, a problem with the isolation valve, or an imbalance in the feedwater rate. The latter can send too much water into the system so it creates excessive steam and increases the pressure.

If you don’t address over pressure conditions it can cause fatal issues. A boiler explosion could result in serious harm to people in the vicinity and elsewhere on the site. It could also potentially cause a massive amount of damage to the building and any equipment within it. The financial repercussions could be huge.

The way to tackle the issue is to use safety valves. They ensure that a boiler cannot exceed a maximum safe pressure level. When the pressure does start to rise, the nozzle in the valve will start to make a simmering noise. As it rises more, a spring will lift a disc in the valve to redirect the stream to a vent. This can make a loud popping noise. The venting steam can also emit a loud noise due to the difference in pressure. However, it will stop the boiler from exploding by bringing the level back down.

In many cases a steam boiler will have two or three sets of safety valves. This provides sufficient measures to address over pressure conditions. If there is ever a situation when the valves need to open, it is important to inspect the boiler and all valves. Then it may be necessary to clean, repair, and recertify each valve.

Tackling the noise with a safety valve silencer

While they are essential, as we said above the valves can cause a lot of noise if they need to open. This should only happen rarely. If it is a regular problem, you need to look at the system because there is a potentially serious issue.

In terms of the noise, a safety valve silencer is a great investment. They can reduce all kinds of noises from the system, including the simmering, popping, and loud venting. This can make facilities much safer.

Ventx is the UK’s leading silencer specialist. We can deliver bespoke equipment to suit all kinds of needs. So, if you have a noisy steam boiler, vents, or other issues, contact us.

We have been assisting businesses with their noise problems for a long time. These issues are particularly serious in the industrial sector. What you need here is silencers you can install in your systems to minimise the sounds. There is more than just one type to choose from, so you must get the right model and a suitable design. We can help with this, offering a solution if you need an autoclave silencer, a model for a generator, or other loud equipment.

Autoclaves, also called steam sterilisers, are normally used in industrial and healthcare settings. They utilise steam under pressure in order to eradicate harmful fungi, viruses, and bacteria. In some cases they can heat treat items. Each model will feature a pressure vessel of some shape or form. You place items in here and then exposure them to a suitable sterilisation temperature for an adequate amount of time. The moisture within the steam moves heat to the items to destroy the spores’ and bacteria’s protein structure or treat the item.

Since we use autoclaves in both healthcare and industrial applications, there has to be different models to suit the differing needs. What we are going to do is discuss the differences between the two here so you can get a better idea of them.

The industrial apparatus

We will start with industrial autoclaves. They have lots of uses, including heat treatment and disinfection. Typically users send materials and components through an autoclave to expose them to pressure and hot steam. This happens commonly with timber to treat it and car tyres to prepare the rubber.

These models can be slightly different in that they tend to be a huge cylinder that you can feed materials though. This is rather than a smaller, sealed pressure vessel. It would not be viable to have something like that for dealing with huge products like long pieces of timber.

Medical steam autoclaves

The uses here also revolve around sterilisation to disinfect items like surgical goods. It is the same with linens, drapes, and medical implements like needles and scalpels. As a result, you can find the autoclaves in hospitals, dental clinics, GPs, and labs.

These models do tend to be sealed pressure vessels. They can range in size from small counter top ones to full cabinets. This all depends on the capacity the user needs. The cycles in medical steam autoclaves are validated and developed to match set industry standards. In the United States for example, the Food and Drug Administration has to clear them. You cannot use them otherwise.

Ask us if you need an autoclave silencer

At Ventx, we are careful to match our silencers with the client’s application. Thanks to our acoustic modelling software, we can analyse your system and design the perfect model. This approach is how we offer the most reliable results.

So, if you need any help from us to create an autoclave silencer or another model, please don’t hesitate to ask. We can work with you to make your facility quieter and safer for everybody.

We have spent a long time providing clients with the finest quality silencers in the UK. With these tools at your disposal, you have what you need to address the damage that noise pollution can cause. There is no universal solution though. Instead, we use acoustic modelling software to design items that will work with your systems. We can offer a steam boiler silencer, models for generators, vent silencers, and much more.

A steam boiler’s mode of operation primarily depends on its use. Yet, the model is similar in each variant. The reason for steam’s use is its capacity to carry high quantities of energy, and the high mobility rate. If you compare to water, steam moves more rapidly. It does not require external propelling forces to move from point A to B inside a pipe either. This makes it a more cost effective option.

Fuel, water, pressure, and temperature are the essential components of the procedure. When combustion happens in a boiler, engine or furnace, you can’t transfer heat directly to the final destination. Steam is a more secure means of shifting energy if you compare to hot metal or naked flame. As a result, it is a common choice when users need an energy carrier.

The 21st century

Many people will view steam boilers as out of date technology. However, they are actually pivotal to several applications in the 21st century. For example they have use in agriculture, brewing, automotive, and more.

One interesting use of the boilers is cement production. Similar to other industries, this is an extremely competitive one. Business owners and investors are always trying to find ways of upping their profits. This is without lowering the product’s quality. They can’t put their workers or consumers’ lives in danger either.

One way to lower production costs is to use a steam boiler and minimise energy loss. Waste heat recovery models are a great investment. They are able to recycle the waste energy instead of simply dispelling it. They can use it to dry raw substances to compliment the power supply.

These boilers have the ability to help create 20 to 30% of the electrical power for cement manufacturing sites. Steam boilers can get noisy though, which is why we use silencers on them.

At Ventx, we make sure we design our silencers properly so that they work for our clients. We are able to produce multiple models as well, ensuring we can cater for most needs. We also adapt to suit the specific challenges with each facility. For example, there could be stricter noise regulations because the site is close to homes.

So, if you currently require a bespoke steam boiler silencer or have trouble with other noise sources, please contact our team. We can find a reliable solution for you.

We fight against the hazard that is noise pollution by providing the best industrial silencer design services. Ventx is able to succeed thanks to our use of special acoustic modelling software. With it, we create silencers that fit into various systems and noisy pieces of equipment. As a result, they will do their job effectively and won’t compromise anything. In fact, they could even boost performance.

The purpose of industrial silencers is to control the sound from various processes. Blower intake, engine, and blow-down models all exist, as do many other options. There are some major differences in the designs and how the silencers work. We want to take a quick look at the variety below.

Absorptive

Firstly, absorptive ones include sound deadening substances. These absorb the sound energy from the air or gas flow, turning it into heat.

Reactive

These models use complex chambers and/or passages. This is to optimise noise attenuation. They do it while preserving application requirements like size, airflow, and pressure drop.

Hybrid

As you can guess from the name, these make use of reactive and absorptive design elements. They merge acoustic materials and airflow path management to lower noise.

Ports and placement

Industrial mufflers and silencers also differ in relation to port type and special features. It is the same with outlet and inlet placement.

You will find two basic forms of ports; the exhaust and inlet silencers. The latter mounts on the intake side of the item or system you are silencing. As for the former, they mount on the exhaust or outlet.

In regards to placement, you can position both outlets and inlets on the side or in-line. As you can see, the designing of industrial silencers is a subject with a lot of variety.

At Ventx, we know how badly noise can impact mental and physical health. Because of this, we take our work incredibly seriously. When you do business with us, we can give you a solution that works. In addition, it will be one that has a fair price.

So, if there is anything we can do for you in terms of industrial silencer design, please don’t hesitate to contact us. We have the skills to work with clients in all kinds of noisy industries.

We are very aware of the problems that noise in industrial settings can cause. It can be harmful to people on the site, locals, and the environment. In addition, it can affect performance and even damage sensitive equipment. That is why we supply bespoke silencers. These are the ultimate tools to use for industrial noise reduction. They can lower the noises coming from fans, ductwork, generators, safety valves, and more.

Industrial hearing loss is a major concern in many harsh industries. However, it is a form of workplace injury that gets less attention than it really needs. The influence it can have on quality of life is something businesses can’t overlook. It does happen sadly since this is an invisible injury.

A vital thing to keep in mind is that industrial hearing loss isn’t a single entity. There are numerous forms and causes of it. There are four main types to remember. We will look at them below.

Tinnitus

This manifests as continuous whistling, clicking, buzzing, and ringing. These sounds appear in one ear or both. It could be persistent, chronic, or temporary, so it is one of the broadest forms of hearing damage.

Acoustic trauma

Repetitive or constant loud sounds at close proximity to your ear can lead to this. As for the damage, it can range from muffled hearing to perforated eardrums. Small perforations can heal in a few weeks, but in the worst cases you may need surgery.

Temporary and permanent deafness

If you experience high noise levels for long enough, you can suffer temporary deafness. Those who get enough time away to rest and recover might get their hearing back. However, if you aren’t able to do this, or the damage is too severe, you can suffer permanent deafness.

You need timely corrective action if you wish to avoid deafness. No matter where you work, exposing yourself to high noise levels could harm your hearing. Saying this, industries like mining, petro-chem, and the military are more dangerous than others. As a result, people need to take extra precautions here.

A helping hand with industrial noise reduction

At Ventx we use acoustic modelling software to supply you with the perfect silencers. You won’t find better tools in your fight against industrial noises. Our installations also stand out because we design them specifically to fit with your systems. This means maximum benefits for you and no issues like a poor installation making the problem worse.

So, if you want to take on industrial noise reduction, please let us know. We can provide the support you need, from initial consultation to design and installation.

Noise issues exist in many locations, but industrial settings tend to produce the most problems. This is why we work to provide our clients with the top silencers in the UK. We use specialist software to develop the most suitable designs, like the steam vent silencer. The result is a safer industrial space as well as less impact on the environment.

The truth is that there are many different kinds of silencer out there. Each one has its own features that make it appropriate for a variety of needs. However, they all hold the important task of lowering noise levels. The model we want to talk about in this post is the pneumatic silencer; it is one you may come across in many different facilities.

Air noise

Pneumatic silencers also go by the names ‘pneumatic exhausts’ and ‘mufflers’. They lower the noise associated with using compressed air. Countless machines utilise it as an extremely effective way of transferring energy. When they release it though, it is nearly impossible to miss because of the loud noise. The dB(A) can reach levels up to 100. To compare, a jet engine is 140 dB(A).

Air velocity is the key

This noise isn’t related to the tube’s or the nozzle’s size. Instead, the key is velocity. Thus, changing the equipment’s size won’t do any good in reducing the sound. What you need to do is find a way to reduce the velocity. You can use the silencers to set in motion a pressure drop. That slows down the air, and reduces the decibels as a result.

Silencers often aren’t actually essential to the productivity of your equipment. Saying this, they may boost performance by reducing vibrations.

You will also find that noise control is written in numerous parts of UK legislation. Examples include The Environmental Noise Regulations 2010 and The Control of Noise at Work Regulations 2005. If you fail to stick to them, you will potentially harm people on and around the site. You could also receive serious fines. Play it safe and use a silencer.

Let us design a steam vent silencer for you

At Ventx, we have assisted an impressive list of clients with noise issues over the years. The industrial silencers we provide protect workers and visitors from excessive exposure. Not to mention, they help you stick to the UK environmental standards.

So, if you need a steam vent silencer or a model for noisy pneumatic equipment from us, please contact the team. You can rely on us to deliver excellent products for every facility.

Of all the dangerous industrial facilities, chemical plants are one of the most hazardous. There are lots of risks to be aware of here. Most notable is the harmful substances on the sites. This can include acids, gases, and more. They can be stored or utilised at very high pressures and temperatures. However, noisy work environments can also be a major hazard. That is why operators need to think about noise control.

Protecting employees

Most chemicals manufacturers will have things in place to keep their employees safe. For example they will likely have controls that reduce the risk of people coming into contact with toxic substances. They will also probably have redundancies in place in case there are leaks. Plus, pipe lines and vessels will generally have safety valves in case there is excessive pressure.

However, it is easy to forget about protecting people from noise. To get it right operators need to have a proactive approach to tackling it. That will provide the best solutions and be far more effective than trying to address the sound levels in the future.

Acoustic enclosures

The best thing to do here is look at how to use noise mitigation measures on the greatest possible stage. For starters there should be a focus on using acoustic enclosures where they can. To do this though, they need to think about things like access control and the kind of conditions in an enclosure. You should not use one if the enclosed space will be even more dangerous for workers. For example, it may result in people working in spaces with insufficient ventilation.

Address every part of the gas movement process

A lot of noise in chemical plants can come from systems to transport and vent gases. The best thing to do here is use silencers and attenuators. You can install them at vents, safety valves, and even air filtration units. The right products can address breakout noise, dramatically reducing the risk to workers. Ideally, you should have a silencer or attenuator near any noise source and outlet.

Let us help you with noise control

At Ventx we appreciate that chemical plants have very strict regulations to meet. They are in place to protect the health of anybody on or near the site. There are also rules in place to minimise the impact on the environment. Luckily, we can deliver solutions to satisfy all of them. At the same time, we will ensure the measures do not harm performance.

So, if you are having trouble with noise control, whether it is a chemical plant or another industrial facility, we can help. Get in touch today to get us to find an acoustic solution for you.

Our main focus is to assist businesses with their noise troubles. Industrial noises in particular can be serious problems. This is because people often have to work in these environments for long periods. They can end up suffering all sorts of negative effects due to the exposure. However, with the help of products such as our diffuser silencer, they can carry on operating in a safer environment.

Silencers have a very important role to play in generators and combustion engines in various vehicles. This is particularly true with construction applications. The goal is to lower the exhaust emissions and noise. There are multiple kinds of silencers in use in this particular area. The one we want to discuss is the low profile model. It is an excellent choice for many needs.

The design

Silencers like these can come in a plethora of shapes and sizes. Examples include round, oval, and rectangular. The specific design for each application generally reflects how much space is available. For example, the profile will be lowest when it is very small spaces.

You can apply these silencers to all kinds of generators. People often choose them for the largest models because they can boost noise reduction if you use them alongside sound enclosures. The drop in noise will be great than if you use an enclosure or silencer separately.

The silencers have to meet the proper guidelines as well. That is why it is always vital to work with a professional designer like us.

Spark arresting

When a generator is within a working environment, you may have to make alterations to the exhaust system. You must do so to make sure that the sparks from the combustion aren’t escaping into the external atmosphere. At the same time, you can reduce the noise.

You can choose spark arresting silencers here. They tend to be a cylindrical shape. They also usually have a modified reactor design. This permits the carbon sparks to circulate in the silencer, until they drop safely into a collection box. It is a necessity to clean the box as part of your maintenance program.

Choose a diffuser silencer

At Ventx, we use our silencers to help you combat noise from all kinds of sources. This includes fans, generators, duct work, and compressors to name a few. You can find any combination of them in industrial settings. This can create really big issues with sound levels. Luckily, we go to great lengths to get our designs right to help bring it down.

So, please get in touch with us if you require a first rate diffuser silencer or any other model. We can guide you, sharing our expertise so you get the best results.

We have been dealing with the issue of industrial noise for years. Our team has been able to assist countless clients by providing the most effective silencer designs. This includes the in-line silencer among others. You could have too much sound coming from your duct work, generators, or compressors. Whatever the circumstances are, we will be able to help.

When dealing with noise in the manufacturing industry, it is wise to start by looking at the laws that surround it. There are all sorts of regulations to govern the amount that is allowed in your workplace. In Europe, the EU Directive 2006/42/EC has details specifically for machinery, safety components, lifting equipment, etc. This is what we will be focusing on in this post. It still applies in the UK, even after Brexit.

What is it?

For those that don’t know, the EU Directive is meant to ensure there is a common safety level with different machinery and parts. One thing it aims to do is tackle noise at the sources. This is normally the most effective and economical way to approach the issue. It is necessary to lower exposure as much as you possibly can to protect people.

Exceeding guidelines

If you exceed the guidelines, it becomes necessary to inspect the cause. A timetable with an action plan shall have to be conceived and executed. Employees shall have to receive sufficient details about the levels and the taken measures. Other necessary information to provide includes details on the risk of hearing loss that the noise exposure could cause. There is also the obligation to use hearing protection.

The maximum noise limit as defined by the European Directive 2003/10/EC is 87 dB(A) Leq. This is for 8-hour work days. If there is a case where national law dictates a lower sound level than that, you need to adhere to it.

In-line silencer design for manufacturers

At Ventx, we supply silencers to keep workers safe. In addition, they help businesses to follow the laws surrounding maximum sound levels. Since we use acoustic modelling software too, we can design a silencer that fits your requirements perfectly.

So, if you would like to do business with us, please let the team know. We can design an in-line silencer for any need, including various types of machinery and equipment. Or, if it is not the most effective design, we can offer an alternative.
