Copeland Emerson ALCO A-AS Suction Accumulator
Reliable suction-line protection designed to help prevent excessive liquid refrigerant from reaching the compressor while supporting controlled oil return in commercial refrigeration and HVAC systems.
A-AS Series Compressor Protection Liquid Slugging Protection Controlled Oil Return Commercial RefrigerationProtect Your Compressor from Liquid Refrigerant
The Copeland Emerson ALCO A-AS Suction Accumulator is designed for installation in the suction line between the evaporator and compressor.
Its main function is to help prevent excessive liquid refrigerant from entering the compressor. The accumulator temporarily holds liquid refrigerant while allowing refrigerant vapour to continue toward the compressor.
An internal oil-return arrangement also helps return collected lubricant to the compressor at a controlled rate.

Technical Overview
Why Is a Suction Accumulator Important?
Refrigeration compressors are primarily designed to compress refrigerant vapour. Excessive liquid refrigerant returning from the evaporator can create potentially damaging operating conditions at the compressor.
A properly selected suction accumulator provides an additional layer of protection by temporarily storing excess liquid refrigerant and allowing it to return to the refrigeration circuit in a controlled manner.
The suction accumulator acts like a temporary safety reservoir between the evaporator and compressor — helping keep excessive liquid refrigerant away from the compressor while allowing normal suction vapour flow.
Typical Applications
How to Select the Correct A-AS Model
Installation Position
The suction accumulator is installed in the suction line between the evaporator and compressor. Correct installation orientation and piping arrangement are important for proper refrigerant and oil return.
Evaporator → Suction Accumulator → Compressor → Condenser → Filter Drier → Sight Glass → Expansion Valve → Evaporator
