Refrigerant R416a, FRIGC FR-12
R416A, commonly known as FRIGC FR-12, is a non-ozone-depleting HFC/HCFC blend refrigerant designed as a direct "drop-in" replacement for R-12 in automotive and stationary air conditioning systems. It is a ternary blend (primarily HFC-134a, HCFC-124, and butane) that works with mineral oil, requires no system modifications, and is often used for medium-temperature refrigeration.
