R407c Refrigerant Gas 10.9KG – Briton
R407c Refrigerant Briton – Difluoromethane, Pentafluoroethane, 1,1,1,2-Tetrafluoroethane
R407c Refrigerant Gas Briton gas 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.
It is not recommended to drop R-407C into R-22 systems on top of the existing charge in cases of low refrigerant levels. A licensed professional should be contracted to completely remove the R-22 and as much of the mineral oil as possible. In the case of compressor change-outs, replacement compressors are already manufactured with POE (polyolester) oil and are therefore more compatible with R-407C than returning the recovered R-22. The recovered R-22 can be sent to a facility for disposal.
It is cost effective to replace R-22 with R-407C before there is an emergency. Preventive maintenance programs should include strong suggestions to replace ozone-depleting refrigerants such as R-22 with environmentally friendly refrigerants and it seems that R-407C has become the front runner. There are many millions of tons of R-22 in air conditioning and refrigeration equipment in use today and most of it is destined to end up in the atmosphere in spite of efforts to curtail this probability.
