Refrigerant R123

123 refrigerant, alias R123, Freon 123, F-123, HCFC-123, trade names are Genetron 123, SUVA 123, Reflube 123, etc., Chinese name trifluorodichloroethane (2,2-dichloro-1, 1,1-Trifluoroethane), English name Dichlorotrifluoroethane, chemical formula CF3CHCl2.
Since R-123 belongs to HCFCs (the second batch of restricted ODS substances Class II Ozone-depleting Substances) - although R-123 still has damage to the ozone layer and has a greenhouse effect, the comprehensive performance of R-123 is very good. (ODP has a low ODP value and a small global warming potential, and the GWP is also small, etc.), so now developed countries and the vast majority of developing countries, including the United States, still have initial installations for new air-conditioning equipment or Re-addition on old equipment; China currently has no restrictions on the production, initial installation, and re-addition of R123 refrigerant.

R-123 main use
The good comprehensive performance of R-123 refrigerant makes it a R-11 (R11, Freon 11, F-11, CFC-11, fluorotrichloromethane, Freon 11) in large central air conditioning (centrifugal chillers). An effective and safe alternative refrigerant for refrigerants; trifluorodichloroethane is also used in foaming, cleaning agents, chemical solvents, etc. for foams.
Although R123 refrigerant used to be a common alternative to Freon R11*** on new refrigeration equipment, R123 and R11 are different in terms of physicochemical properties, theoretical cycle performance and compressor oil, so they are initially installed as R11 refrigerant. After-sales maintenance of refrigeration equipment, if you need to add or replace refrigerant, you can only add R11, usually can not directly replace R11 with R123 (that is, usually can not be replaced by blood exchange).
Steel drum packaging: 100kg/barrel.
