Emerson Flow Control (Alco) 060820 4-Ton Accumulator R22 3/4" ODF

The Emerson Flow Control (Alco) 060820 Suction Accumulator is a refrigerant protection component used to prevent liquid refrigerant from entering the compressor. It is designed for 4-ton R-22 systems and features a 3/4" ODF solder connection for integration into the suction line. The accumulator temporarily stores excess liquid refrigerant during flood back conditions, allowing only vapor to continue to the compressor in HVAC systems. This helps protect internal compressor components from damage and maintains stable lubrication return. It is installed in air conditioning and refrigeration systems during servicing or replacement to ensure reliable operation and system protection under varying load conditions.
