Our 3-in-1 refrigeration component combines a suction line accumulator, liquid receiver, and heat exchanger into a single compact unit.
This integrated design improves refrigerant circulation, prevents compressor liquid slugging, and enhances cooling efficiency.
Ideal for refrigeration systems, cold rooms, heat pumps, and HVAC/R equipment requiring space-saving and reliable solutions.
Key Functions:
• Liquid Storage: Acts as a liquid receiver to balance refrigerant charge.
• Gas-Liquid Separation: Functions as a suction accumulator to protect compressors.
• Heat Exchange: Provides subcooling and reduces refrigerant flash gas, increasing system efficiency.
