Description
The Copeland 577-0421-01 Suction Accumulator is a precision-engineered refrigeration component designed to safeguard compressors from liquid slugging and oil carryover — two of the most common causes of compressor failure in refrigeration and air conditioning systems.
Product Overview
Suction accumulators are installed in the suction line between the evaporator and the compressor. They temporarily hold any excess liquid refrigerant or oil that may be present in the suction vapor, releasing it slowly in a controlled manner so that only dry refrigerant vapor enters the compressor. This protection is critical during system startup, defrost cycles, and any condition that may cause refrigerant floodback.
