Frogen® R-134a has been developed by Frogen® Ltd. to serve as one of the key substitutes for CFCs and HCFCs. Frogen® R-134a is a long-term, environmentally safer, non-ozone depleting substitute. As a refrigerant, it possesses similar energy efficiency and capacity characteristics as Frogen® R-12 and has an intrinsically low toxicity. Frogen® R-134a is the alternative refrigerant of choice in automobile air-conditioning. It may be used in residential and commercial refrigeration, as well as commercial, and industrial air-conditioning.
