Supply DuPont Refrigerants R134A

R-134a refrigerant, alias R134a, HFC134a, HFC-134a, tetrafluoroethane, tetrafluoroethane Chinese name, English name of 1,1,1,2-tetrafluoroethane, chemical name 1,1,1,2-- tetrafluoroethane, suppliers CH2FCF3. Because R-134a belong HFC substances (non-ODS substances Ozone-depleting Substances) - and therefore completely destroy the ozone layer, most of the world is currently recognized and recommended environmentally friendly refrigerant, is currently the mainstream environmentally friendly refrigerants, widely for the initial installation and maintenance process on new refrigeration and air conditioning equipment in the add. Main purpose: R-134a as the most widely used in low temperature environmentally friendly refrigerant, HFC-134a due to the good overall performance, making it a very effective and safe alternative to CFC-12, and is mainly used in the use of R- 12 (R12, Freon 12, F-12, CFC-12, Freon 12, dichlorodifluoromethane) refrigerants in most areas, including: refrigerators, freezers, drinking fountains, car air conditioners, central air conditioners, dehumidifiers, cold storage, commercial refrigeration, ice machines, ice cream machine, refrigeration condensing units and other refrigeration equipment, but can also be applied to aerosol propellants, medical aerosol insecticide propellant, polymer (plastic) physical blowing agent, and magnesium alloy to protect gas. Although R134a refrigerant is a substitute on the newly installed refrigeration equipment, the most popular choice freon R12, R134a and R12 but because of physical and chemical properties, theoretical cycle performance and compressor oil, etc. are not the same, so for the initial installation of the refrigerant R12 refrigeration equipment Repairs, if you need to add or replace the refrigerant, still only add R12, R134a usually can not replace direct R12 (That is usually not performed shake-style replacement).
