DISCHARGE LINE MUFFLERS
The function of a Discharge Line Muffler is to reduce pressure
pulsations downstream of the Compressor.
Applications
The Muffler is designed to be installed directly after the compressor. Henry
Technologies’ Discharge Line Mufflers are suitable for use with HCFC and
HFC refrigerants, and their associated oils, as well as other industrial fluids
non-corrosive to steel and copper.

How it works
The Muffler reduces noise, due to gas pulsations, by allowing the gas to
expand inside muffler chambers. Mufflers have internal baffles which are
designed to dampen and smooth out low and high frequency compressor gas
sound waves.

B

Discharge Line Mufflers are UL and C-UL Listed by Underwriters
Laboratories, Inc. Additionally, larger sized Discharge Line Mufflers can be
CE marked in accordance with PED. See table below.

Materials of Construction
The main body and internal baffles are made from carbon steel. The
connections are made from plated carbon steel.

Selection Guidelines

(2X) ODS

Select a muffler with a connection size that matches or exceeds the
discharge line size. Larger mufflers will tend to remove more pulsations due
to the larger internal volume.
