ERF Model ERF Refrigeration Hvac Controls Parts For Air Cooler
Description:
·Model ERF/FRFW thermal expansion valves are used to adjust the liquid refrigerant supply volume to the evaporator and they are suitable to
various refrigerants and different charging condition. It meets the requirements of the cold storage facility, ice maker and dehumidifier as well as t
the refrigeration and air conditioning requirements under varied evaporation temperature.
Application
• Traditional refrigeration
• Self-contained refrigerators
• Transport refrigeration
• Supermarket refrigeration
• Temperature range: -40 °F to +50 °
