TECNAC SDS series silencers – distributed by GE.RE.CO. srl of Cesano Boscone Milan – are suitable for reducing noise caused by gas pulsations in the discharge line of compressors in refrigeration and air conditioning systems. These pulsations mainly come from piston compressors or screw compressors.
The silencers are basically made up of the casing inside which the deflection plates are placed. The internal volume of the devices mainly depends on the displacement of the compressor, although, for the choice of the silencer, the frequency and intensity of the sound waves must be considered.
The SDS exhaust silencers, available both for HFC and HFC410A refrigerants, and for CO2, do not act on the mechanical vibrations transmitted through the tubes from the compressors; this is the specific role of VA vibration dampers.
