R407c Refrigerant Gas Supplier - Refrigeration Gases

R407c is a hydrofluorocarbon (HFC) blend refrigerant used in air conditioning and refrigeration systems.

It is a non-ozone-depleting gas but has a high global warming potential (GWP).

R407c is a zeotropic mixture, requiring careful handling due to its temperature glide during phase change.

R407c Refrigerant Gas is a zeotropic blend of HFC-32 (23%), HFC-125 (25%), and HFC-134a (52%). It is commonly used in air conditioning and refrigeration systems as a replacement for R22. Below are its key specifications and technical properties:
