Silencers absorb and reduce noise emitted from machinery and other sources for the safety of everyone exposed and for regulatory compliance. Silencers may vary in terms of their physical location relative to the item being silenced for example, inlet silencers mount on the intake side while exhaust silencers mount on the outlet or exhaust of the device. There are many applications for silencers such as noise reduction for industrial engines and turbines, air or gas compressors, vacuum pumps, or valves. Common sources of noise at industrial sites include restrictions in piping (e.g. relief valves, control valves, orifices etc), excessive velocity flow in pipes, engines/turbines and compressors/blowers.

At Fluid Kinetics, we take unique and innovative approaches to noise attenuation and it shows in our silencer designs. Our absorptive silencers use layers of sound adsorbing materials to soak up the noise energy from the flow of fluids while our reactive silencers are tuned to handle pressure drop using intricate passages within its shell. We also offer silencers that combine both designs into one effective and compact silencer. With our Fluid Kinetics ‘custom-built’ approach, you can build a silencer just for you. You can pick the length and orientation of the inlet (horizontal or vertical) or have your silencer placed in a ‘slip-in’ or ‘inline’ position.

Picking the right silencer requires an analysis of certain physical, performance and mounting specifications. In order to design your silencer, we need information such as the size of interconnecting piping, the maximum pressure and flow rating, and your expectations for noise attenuation (measured in decibels, dB).

Silencer Options/Add-ons
 
Multiple Inlets: 

Venting multiple lines through same silencer housing reduces space requirement and installed cost. It also makes it easy to manage gas from different sources.

Portable Pipeline Blow down Silencer: 

Silencer with integral separator can be installed on a trailer for easy movement from site to site.

Flexible Joint: 

Conventional drip pan arrangement leaks noise through the drip pan arrangement and poses a safety risk to plant personnel. Non-pressure containing flexible joint eliminates noise leak, enhances personnel safety, eliminates pipe system loops for thermal expansion, and allows higher inlet pressure reducing pipe size.

Weather Hood: 

Excess rain and snow can potentially fill up the silencer resulting in a safety hazard if not adequately drained or externally protected. A weather hood provides additional protection to keep water and snow from getting inside. 

Bird Screen: 

Safety vent valves are seldom opened and therefore offer good nesting area for birds. Specially designed bird screens help protect bird species.

Removable Diffusers: 

This unique modular option allows for the replacement of installed diffusers to allow for a different flow condition without the need to replace the entire silencer!

Rental Silencer:

Pre-fabricated modular silencers are readily available to reduce noise emission during plant commissioning.
