R-134a is an inert gas used primarily as a "high-temperature" refrigerant for domestic refrigeration and automobile air conditioners. R-134a is the global standard for new mobile air conditioning and can be utilized to retrofit existing R-12 mobile air conditioning systems. Other uses include plastic foam blowing (as a cleaning solvent), a propellant for the delivery of pharmaceuticals, wine cork removers, gas dusters and in air driers for removing the moisture from compressed air.
R-404A is a blend of HFC refrigerants commonly used for medium and low temperature refrigeration applications and offers excellent capacity and efficiency as a replacement for R-502 and R-22 in new and existing R-502 equipment. It is non toxic and non flammable meeting the highest A1/A1 classification.
