Henry Group Industries Discharge Line Muffler ODS Mufflers

The Henry Group Industries Discharge Line Muffler (also called a refrigeration discharge muffler or compressor discharge muffler) reduces noise in the discharge line of refrigeration and air-conditioning systems. These ODS (solder connection) mufflers install in the hot gas line and quiet the pulsation and vibration that compressors create.

How It Works:

• Internal baffles are designed for minimum pressure drop.
• The baffles change the velocity of the discharge gases passing through the muffler.
• This dampens high-frequency sound waves from high-speed compressors.
• It also muffles pulsating waves in both low-speed and high-speed compressors.

Key Features:

• Robust design for long service life
• Bi-directional flow for flexible installation
• Special baffle design for maximum flow and minimal pressure drop
• Carbon steel body and internal baffles, with plated carbon steel connections
• Powder-coated finish, tested to exceed 500 hours of salt spray
• Oil drain passage, so oil does not collect when the muffler is installed in the correct orientation
• Manufactured and tested to relevant pressure vessel codes

Performance:

• Maximum working pressure of 31 barg (449.6 psig)
• Operating temperature range of 0°C to +121°C (+32°F to +249.8°F)
• Compatible with CO2, HCFC and HFC refrigerants where materially compatible. Select models also suit A2L, HC and HFO refrigerants where materially compatible.

Henry Group Industries has been making commercial refrigeration components since 1914. Install the muffler directly after the compressor, sized to the compressor discharge line. This gives quieter system operation with negligible loss in efficiency.
