Refrigerant-407c

R-407c is a mixture of hydrofluorocarbons used as a refrigerant. It is a zeotropic blend of difluoromethane (R-32), pentafluoroethane (R-125) and 1,1,1,2-tetrafluoroethane (R-134a). Difluoromethane serves to provide the heat capacity, pentafluoroethane decreases flammability, tetrafluoroethane reduces pressure. R-407c cylinders are colored burnt orange. A blend of R-32, R-125 and R-134a has very similar properties to R-22 in air conditioning equipment. R-407C has the closest property match to R-22 compared to other blends on the market. It can also be used in medium temp R-22 refrigeration systems. New systems built with R-407C must have POE lubricants and retrofitted R-22 systems would need the residual oil flushed with POE.

Chemical formula: CH2F2, CF3CHF2, CH2FCF3
