Henry Technologies S-6413 Muffler

The Henry Technologies S-6413 Discharge Line Muffler is a critical component for 1 3/8" ODS piping, engineered to drastically reduce compressor gas pulsations and the resulting acoustic noise in high-capacity refrigeration systems. Constructed with a heavy-duty carbon steel body and plated carbon steel connections, this muffler utilizes internal baffles that change gas velocity to dampen both low and high-frequency sound waves. This sound reduction device is designed for direct installation after the compressor, ensuring minimal pressure drop while maintaining system efficiency. It is fully compatible with HFC, HCFC, and CO2 refrigerants, as well as A2L and HFO blends and their associated oils. With a maximum working pressure of 451 PSI (31 Bar) and an allowable operating temperature range of -15?F to +250?F, the S-6413 provides a bi-directional flow solution that prevents harmonic pulses from traveling downstream to the condenser or evaporator, protecting sensitive system components from mechanical stress.

• Broad Refrigerant Compatibility: Suitable for use with traditional HFCs and modern, low-GWP A2L refrigerants.
• Optimized Internal Design: Features an internal baffle configuration that mitigates noise with negligible loss in system capacity.
• Robust Industrial Construction: Built with carbon steel to meet UL and C-UL standards for high-pressure environments.
• Installation Versatility: The bi-directional flow and oil drain passage allow for flexible mounting orientations.
• Pulsation Control: Specifically targets the harmonic vibrations that often lead to pipe fatigue and leak points.

For maximum effectiveness, the muffler should be installed in the discharge line as close to the compressor as possible, and always before the oil separator. When mounting horizontally, ensure the label is at the top center to prevent oil trapping.

While the S-6413 is rated for HFCs, HFOs, and A2Ls, always verify material compatibility for specific hydrocarbon applications. This unit is primarily designed for Group 2 gases under PED classifications.

No, this device is designed to attenuate noise from gas pulsations. To manage mechanical vibration transmitted through the piping, a dedicated vibration eliminator should be installed between the compressor and the muffler.
