4.6MPa Copper Accumulator – R410A/R22 Refrigeration Liquid Trap,Prevents liquid refrigerant from reaching the compressor. ODF solder connections. Compatible with R410A, R22, R134a. Max working pressure 4.6MPa. U-tube design for maximum flow and oil return.
Our Copper Accumulator (Suction Line Accumulator) is installed between the evaporator and compressor to prevent liquid refrigerant from entering the compressor, avoiding costly liquid slugging and compressor damage. It acts as a temporary reservoir — liquid refrigerant and oil collect at the bottom and evaporate gradually before returning to the compressor as vapor.
The inner U-tube design ensures maximum refrigerant flow with minimum oil entrapment, while the copper shell provides excellent corrosion resistance and durability.
