R-507 is a mixture of hydrofluorocarbon (HFC) refrigerants HFC-125 and HFC-143a. It is an azeotrope, is non-flammable, and has zero ozone depletion potential (ODP). These properties make it a candidate refrigerant for applications where safety and consistency of performance are needed. It is a safe, effective alternative to some chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) refrigerants, including R-502.

This hydrofluorocarbon (HFC) has similar qualities to R-502 and performs well in commercial refrigeration systems used in supermarkets or transport refrigeration where safety is paramount
