VENT SILENCERSThe silencers are designed to reduce the noiseproduced by the venting of pressurised gas toatmosphere especially : air, steam & gases (nitrogen,oxygen etc...).They are installed downstream from all devices discharging a compressed gasto atmosphere such as : safety valve, ejector, snort-valve, relief/start up valve,blowdown tank, boiler, etc.
Typical applications
•Combined Cycle plant - CCP
•Cogeneration - CHP
•Power plants (New application or replacement)
•HRSG and Combustion Boiler •Waste–to-energy plant •Heavy industries•Compressors•Petrochemical industries
