Exhaust silencer SM EVO®

enginegasindustry

Engine exhaust silencers SM EVO® Our engine silencers are designed to attenuate the noise generated by the exhaust gases of internal combustion engines in various fields of application: energy, industry, railway, military, marine, mobile, emergency, nuclear, cogeneration, biogas, methanisation, UPS… Our new generation of EVO® silencers have been optimised by our aeroacoustic engineers. Using the latest generation of finite element calculation software, this optimisation has enabled us to digitally validate the highly complex behaviour of the aeroacoustic phenomena in our silencers. Our numerical models have been qualified by dynamic tests in our laboratory and on industrial sites. Our SM EVO® silencers are fully welded in carbon steel, with internal and external protection provided by a high-temperature black primer paint. All our silencers are internally insulated to reduce the heat release and to achieve low surface temperatures. Our standard silencers are available from stock and can be delivered very quickly. The direction of gas flow must be respected. Our silencers can be placed horizontally or vertically depending on the available space and the layout of the exhaust system. Before any installation, it is important to read our installation, operation and maintenance manual OMM-SM. All our silencers > 50kg are equipped with welded lifting rings. BOËT StopSon's range of engine exhaust silencers SM EVO offers sound attenuation from 10 dB (A) to 60 dB (A) or more. Our silencers are based on two principles of attenuation: Attenuation by dissipative effect Reactive attenuation : - Impedance break: reflection of the wave - Quarter wave, resonator: signal phase shift
