All About Our Inline Silencers

Here at Ventx, we specialise in silencer design for a range of industries, and over our many years of existence, we have built up a great list of clients. Today, we are going to turn our attention to our inline silencers, looking at the problem that these types of silencers solve, the options available to you, and providing more details about our service.
The Problem
When looking at silencer solutions, the problem may be that whilst the noise attenuation measures deal with noise produced by exhaust and venting devices, noise pollution is still being created through power generation or other processes at an intermediate stage. Your team and any visitors will be exposed to this noise, and this is an even bigger problem when working in such an environment for long periods of time, or on a regular basis.
The Solution
By implementing the use of inline silencers, you are dealing with noise created by gas flow within ducting or other conduits. This solution means that when a flow of gas that passes through a chamber or junction (or from one diameter or pipe to another), which would otherwise produce unwanted noise, balances within the system, removing the noise at the source.
The Options
Our inline silencers make use of the same elements of design as a vent silencer
, with the main concern being to reduce the vibration, which thereby reduces the valve noise. For this purpose, there are two options to select from when considering inline applications, including control valve silencers and direct inline silencers. Control valve silencers offer a drop in pressure or back pressure, combining a diffuser design with an absorptive section, in conjunction with a control valve. On the other hand, direct inline silencers create as little pressure loss as possible, and use only the absorptive section. Both types can be used in pressurised systems to an appropriate pressure design code. We always provide silencer inlets designed and manufactured with reference to a design code in order to provide a required back pressure and select the correct valve.
Bespoke Service
At Ventx, we custom-build your inline silencer system to produce the best performance possible for your environment. We start with an acoustic analysis, where we record the noise levels and their frequencies. If not an already existing facility, we can also use your specifications and model the acoustic properties of the proposed installation through our computer software. Once the design of your inline silencer is finalised, we manufacture it from long strand fibreglass acoustic packing as the absorption material. This makes up the core of the product, which is then supplied in a custom-fabricated inline silencer housing, or used to be inserted into your already existing pipework.

Key Industries
We offer our industrial silencer design services to power generation, waste treatment, manufacturing, and plenty more industries. What do they all have in common? They all involve processes that consists of the transfer of gas under pressure. Depending on the specific industry, this has may be air, steam, or another chemical, which must leave the system and be released into the atmosphere.
The Importance of a Vent Silencer
As any industry professional would know, working in these environments, the process of releasing pressurised gas is very noisy. A vent silencer is vital in order to reduce this noise to an acceptable level. In fact, in order to comply with the current legislation regarding noise pollution, an exhaust silencer is a must. Not only that, but the design of the silencer is of great importance as it must be perfectly designed in order to provide the necessary performance.

All About Our Silencer Configuration

At Ventx, we are on a mission to bring our customers the very latest in industrial silencer design.  This means exploring every avenue of silencer design and construction, and matching each application with the most appropriate setup.  As a result, Ventx Silencers have remained at the forefront of industrial silencer technology for the last three decades.
Biscuits, cakes and bread – all these products are made with the many of the same basic ingredients, but they are combined in different ways to achieve different results.  Exhaust silencer design is similar; silencer design companies use the same materials and components over and over again in their products, but it’s the way these components are set up and installed which endows each model with its individual characteristics.  As a result, we can fine tune every silencer to provide optimum performance in its particular application.  Silencer configuration is therefore a crucial consideration in the commissioning of any industrial equipment which will necessitate some form of noise attenuation.
On the face of things, vent silencer design may seem like a relatively simple issue, as certain common types of silencer are widely accepted to be best suited to particular purposes.  For example, control valve silencers are designed to limit the noise produced by the venting valve of a pressurised system.  A carefully designed diffuser in conjunction with acoustically absorptive material moderates the pressure in order to reduce the level of sound when the control valve opens.  Contrast this with direct silencers, which are also installed in-line but rely on an acoustic core for attenuation.  These two silencer types may appear similar to the untrained eye, but in reality there are many subtle but key differences which distinguish, not just the different models available, but even examples of the same model which have been manufactured to a slightly different specification.  The upshot of this is that a silencer cannot be relied upon to provide optimum performance – or even to be effective – unless it is carefully configured and matched to the intended application.
Ventx have over forty years of experience in the field of acoustic design, and we put this expertise to work in the development of bespoke silencers for any situation.  Key to the Ventx process is our unique computer software which allows us to produce optimised blueprints for all types of units.  We thus remove the trial-and-error from the process of silencer design.  We can create installations which we know will meet our customers’ requirements exactly, in terms of physical dimensions, level of attenuation, pressure code, and so on.  It is this specialist knowledge which has established Ventx as leading providers of industrial silencer solutions to national and international companies across a range of industries.
The legislation covering the environmental effects of industry is strict, but this is by necessity – none of us would want to return to the conditions of the industrial revolution.  By enlisting the help of experts in silencer configuration, companies can meet their legal obligations and maintain the character of their surroundings too.

Silencer Configuration Blog

Ventx is a proud owner of over 40 years of acoustic knowledge combined with 30 years of quality manufacturing experience. This has provided us with the expertise in providing a high quality and effective silencing solution to the noise that can often pollute industrial environments that utilise pipework, plumbing and ventilation systems. You may not be aware of the existence of industrial silencer solutions, nor realise that you could benefit from utilising them in your workplace; today, we will outline the silencer configuration we offer, and demonstrate how it can be of benefit to you.
What is a silencer?
Pipe work that has substances, gas and steam flowing through it can produce uncomfortable and irritating noise. This can be a nuisance and distraction to your work day, which can ultimately limit your work performance and efficiency. By fitting one of our custom-built vent silencer designs, this noise can be curbed, reduced and significantly quietened, to make your professional experience a more pleasant one.
What service do we offer?
Noise is a particularly difficult sense to measure, as it can be hard to tell when something is quieter or louder than before. Our advanced computer software can pick up even the most subtle changes in noise, giving an accurate reading that will allow our team to fit you with the perfect silencer.
Our team begin by looking at the flow rate of the substance passing through your pipes; this allows us to measure the exact diameter required for fitting your ventilation system. This will also prevent erosion of the silencer over time, saving you time and costs in the long run. The length of the silencer you choose is dependent on how reduced you wish the noise to be.
We offer a number of different type of silencers, dependent on your specific needs. Gas ejector silencers are ideal for pipes with steam or hydrocarbon gas flowing through them, whereas direct line silencers absorb sound rather than compress it in order to curb noise pollution. We also offer control valve silencers, which vary the flow of the substance as it flows and leave your pipes and ventilators. Regardless of your infrastructure, at Ventx we can accustom to your needs.
Furthermore, we can work around the pre-existing structure of your pipe and ventilation systems. There is no need to worry about time consuming and costly plumbing works; our industrial silencer solutions can be inserted into the existing pipework, either as a whole unit or an acoustic core. The result is an absorbed and higher frequency, which is harder for human ears to hear and results in a less noticeable noise.

All About Control Valve Silencers

Here at Ventx, we offer our clients industrial silencer designs, including gas ejector silencers, direct line silencers, vent discharge silences, and control valve silencers. Today we’re going to shine the spotlight on the latter option.
What is a Control Valve Silencer?
A valve control silencer is used as a type of diffusion technique that reduces pressure, a diffuser installed downstream from a control valve. They are able to decrease the pressure of the gas flow whilst at the same time as absorbing as much sound as possible. This process makes use of both an expansion chamber, and an absorptive core. It is also possible to design it in a way that the slot width and length offers the correct attenuation of the diffuser noise spectrum.
How Does it Work?
The way the control valve silencers work is different from other kinds of path treatments as part of its main functioning is to absorb noise energy. Used in combination with a diffuser, for control valve applications operating at high pressure ratios, it’s possible to use a series approach. This enables you to split the total pressure drop between the control valve and a diffuser, minimising the overall noise level. As steam or gas enters the silencer (through the diffuser), the air expands into the different holes to the expansion chamber. Therefore, the noises that would be created by releasing gases into the atmosphere is greatly reduced.
Why Ventx?
Here at Ventx, we are considered leaders when it comes to control valve silencer manufacturing. These silencers are about to reduce undesired noise pollution when releasing pressurised gas, including oxygen and nitrogen.
