R438A (ISCEON® MO99)
ChemoursTM ISCEON MO99 (R438A) is an easy to use, non-ozone depleting HFC refrigerant blend. ISCEON MO99 is ideally suited as an R22 replacement for all air conditioning and chiller applications with performance, capacity, mass flow and pressure characteristics a close match for R22. It has advantages over ISCEON MO29 where the expansion valve has a fixed orifice or is closely sized to the capacity of the system, whilst it has better capacity compared to MO59.
ISCEON MO99 is compatible with traditional and new lubricants, providing easy, quick and cost effective retrofits and can be topped up during service without removing the entire refrigerant charge. As ISCEON MO99 is a blend, it should be removed from the cylinder as a liquid when charging a system.
