R422A (ISCEON® MO79)

ChemoursTM ISCEON MO79 (R422A) is an easy to use, non-ozone depleting HFC refrigerant blend of R125, R134a and R600a.  ISCEON MO79 is typically used to replace R22, R502 and blends such as R402A, R403B, and R408A in medium and low temperature refrigeration systems.  ISCEON MO79 has a significantly lower discharge temperature compared to R22, and improved cooling capacity with a gain of up to 15% at low temperature conditions. 

ISCEON MO79 is compatible with traditional and new lubricants, providing a quick, cost effective retrofit.  It has a lower global warming potential that R404A and R507, and can be topped up during service without removing the entire refrigerant charge.  As ISCEON MO79 is a blend, it should always be removed from the cylinder as a liquid when charging the system.
