COMPRESSOR PROTECTIVE DEVICES

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.

Technical Specifications

Maximum working pressure = 450 PSI (31 Bar)

Allowable operating temperature = +32°F to +250°F (0°C to +121°C )

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.

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.

Selection Guidelines

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.
