Refrigerant R407C is a mixture of hydrofluorocarbons used as a refrigerant. It is an azeotropic blend of R 32, R 125, and R 134a (20/40/40)."" Applications include residential and commercial air conditioning systems, non-flooded evaporator chillers, and some commercial refrigeration systems. Since R407C has similar properties to R-22, it is possible (with modifications) to use it in the same equipment designed for R-22 today.
