FreonTM 407C refrigerant performs similarly to HCFC-22 under evaporator temperatures ranging from –7 to 10 °C (20 to 50 °F). It is designed for use in new equipment and as a service refrigerant for existing HCFC-22 air conditioning, heat pump, and medium temperature refrigeration equipment.

Jun 9, 2022 · The R-407C refrigerant consists of three HFC (hydrofluorocarbons) components. They include R-32 (difluoromethane), R-125 (Pentafluoromethane), and R134A , also known as 1, 1, 1, 2- tetrafluoroethane.

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. [ 1 ]

New tables of the thermodynamic properties of Freon™ 407C refrigerant (ASHRAE designation: R-407C [23/25/52]), a near azeotropic blend of HFC-32/HFC-125/ HFC-134a, have been developed and are presented here. These tables are based on extensive experimental measurements. Equations have been developed, based on

125/HFC-134a, assigned R-407C by ASHRAE) serves as a non­ ozone-depleting replacement for HCFC-22 in various air-condi­ tioning applications, as well as in most refrigeration systems.

R-407C is a non-ozone-depleting R-22 replacement because of its similar cooling capacity, energy efficiency, and pressures as R-22 in systems, as well as replace R-502 for some existing medium-temperature applications. What is R-407C?

R-407C is a ternary mixture non-azeotropic composed of R-32, R-125 and R-134a. It is chemically stable, has good thermodynamic properties, low environmental impact and very low toxicity.

R-407C is a "non azeotropic” HFC blend. It is mainly used in air conditioning applications where R22 would have previously been used. Use a polyol ester (POE) oil. Check with Climalife regarding the viscosity of the oil selected for your application, and the miscibility with the fluid under consideration. Refer to the Safety Data Sheet*.
