Chemours™ Freon® MO59 (R-417A)

Chemours R-417A: A Cost-Effective Retrofit for R-22 in AC and Refrigeration

Chemours R-417A (Freon™ MO59) is a hydrofluorocarbon (HFC) refrigerant designed as a cost-effective replacement for R-22 in direct expansion (DX) stationary air conditioning (AC) and medium-temperature commercial refrigeration systems. Its compatibility with mineral (MO), alkylbenzene (AB), and polyol ester (POE) oils eliminates the need for lubricant changes, making retrofitting faster and more economical.
