Refrigerant R-421A is a non-ozone-depleting HFC blend engineered as a direct replacement for R-22 in existing systems. It delivers reliable performance while allowing a smooth transition away from ozone-depleting refrigerants.
One of the key advantages of R-421A is its broad lubricant compatibility. It can be used with mineral oil, alkylbenzene (AB), or polyolester (POE) oils, helping reduce retrofit complexity and minimizing system modifications.
