The refrigeration compressor is designed to compress vapor only. A suction line accumulator prevents compressor damage from a sudden surge of liquid refrigerant and oil which could enter the compressor from the suction line.
 
Protects the compressor, especially duringIntermittent operation.
Liquid is temporarily held and metered back to theCompressor,                        along with any oil, at a controlled rate. Solid copper connections.
"U" tube design for maximium flow of refrigerant andminimum                          oil entrapment.
