Information about our venting silencers
Venting silencers are designed to attenuate the noise caused by the venting of pressurized gaseous fluids.
The efficiency of a venting silencer is based on two principles of noise reduction: controlled, silent gas expansion, followed by a technology that absorbs residual noise after expansion.
Our mastery of aero-acoustic phenomena enables us to precisely control the efficiency of the expansion module, from subsonic to various sonic regimes. The phenomenon is fully controlled and optimized for the particular conditions of the process.
Our calculation results have been validated on the world’s largest valve testing facility (Framatome Karlstein).
