Refrigerant R437A


R437A is an HFC refrigerant that can directly replace existing automotive air conditioning systems and stationary refrigeration systems using R-12, as well as fixed refrigeration systems using HCFC-mixed refrigerants such as MP39, MP66, and R409A. R437A can also be used to replace R413A. HFC refrigerant, ODP is zero, compatible with traditional and new lubricating oil. In most cases, the replacement process does not require a change of lubricating oil type and the existing equipment can continue to be used.


R437A refrigerant steel cylinder is a pressurized container. Keep it away from fire, heat, and direct exposure to sunlight. It is usually stored in a cool, dry, and ventilated warehouse. When handling, light loading and unloading should be carried out to prevent cylinder and valve and other accessories from damage.


As a medium and high temperature refrigerant widely used today, R437A refrigerant is mainly used in catering refrigeration, supermarket display cases, food storage and processing, household refrigerators, ice makers.
