Henry Discharge Line Mufflers

The function of a Discharge Muffler is to reduce noise in the discharge line of a refrigeration or air-conditioning system. Mufflers have internal baffles designed for minimum pressure drop. These baffles change the velocity of the discharge gases passing through the muffler. Resulting in a dampening effect on high-frequency sound waves on high-speed compressors. Pulsating waves are also muffled in both low-speed and high-speed compressors.

The muffler is designed to be installed directly after the compressor. They are sized to the discharge line of the compressor.

The product range is designed for use with HCFC and HFC refrigerants, along
with their associated oils.
