Refrigerant R-404A
Automotive Air Conditioning Gas
R-404 is a pseudo – azeotropic mixed refrigerant composed of the three ingredients R-125, R-134a, and R-143a, and belongs to the HFC family of refrigerant, used in commercial refrigerator equipment for low and medium temperature ranges. It possesses outstanding properties as a refrigerant for showcases, refrigerated vehicles, ice makers, and other equipment.
APPLICATIONS:
- Commercial Refrigeration: Refrigerated Counters, Cold Rooms, Display Units, Ice Makers, Refrigerated Vending Machines, Refrigerated Warehouses, Ice Skating Rinks
- Industrial Refrigeration: Refrigeration systems for the Processing Industry, Chillers
- Domestic Refrigeration: Freezer and Domestic Refrigerator
- Transport Refrigeration: Truck and Van that carry Refrigerated Containers.
USAGE INSTRUCTIONS:
- Although R-404A was developed as a substitute for refrigerants such as R-22 and R-502, and since it does not have mutual solubility with substances such as mineral oils or alkyl benzene oils conventionally used in R-22 and R-502, there is a need to either use compound oils having mutual solubility with substances such as polyol ester oils, or to take special measures to return oil to compressors.
- Since R-404A is a pseudo- azeotropic mixed refrigerant, it does not undergo large changes in composition, but when filling equipment with it from a container, filling must begin from the liquid phase. Never carry out fillings from the gas phase under any circumstances.
