DuPont™ ISCEON® MO79 is a replacement for R-502 and HCFC-containing blends (e.g., HP80, HP81, and R-408A) used in medium- and low-temperature refrigeration systems with expansion valves sized with R-502. ISCEON® MO79 can also be used to replace R-404A and has a 23% lower global warming potential (GWP) than R-404A. It is compatible with traditional and new lubricants, providing a cost-effective R-404A or R-22 retrofit.
Note: If you are looking for a retrofit refrigerant that can be used for low, medium, and high temperatures, please consider ISCEON® MO99™.
ISCEON® MO79 has a significantly lower discharge temperature compared to R-22, reducing the need for injection cooling in low-temperature applications. It is non-ozone depleting, has a lower global warming potential than R-404A and R-507, and can be topped off during service without removing the entire refrigerant charge.
