R427A is a blend of HFC refrigerants designed to retrofit R22 installations. R22 is a HCFC and therefore is been phased out. R427A offers similar performance to R22 usually without any need for modification to the existing R22 installation. It can be used to retrofit low temperature refrigeration equipment and air conditioning installations. It is non toxic and non flammable meeting the highest A1/A1 classification. R427A, as a blend of HFCs, requires polyolester (POE) lubricants but is tolerant of high levels of alkylbenzene or mineral oils of up to 10%.
