This silencer works accordingto the splitter silencer system. It can be used inside pressure piping systems to reduce the noise from valves, compressors, pumps, etc. The absorbers are designed on the basis of media (pressure, sort of media, temperature, and density).
The internal splitters are designed for higher streaming forces and this is the reason why we use the following set up:
NOTE: Pressure vessel directive:
The vessels of the pressure silencers are in most cases subject to a pressure equipment directive:
The reactive silencer type is used, where noise at low frequencies (with high energy) or noise with tonal components must be reduced. It can be used inside pressure piping or exhaust system connected with the environment. Reactive silencers can be designed only for reducing the noise of specific frequency band, e.g. number of fans x rotation. To reduce, additionally, higher or other frequency noise an absorption part becomes necessary which leads to a combined reactive – absorption silencer.
The advantages are:
