Ametron®  Refrigerants R-417A refrigerant is a hydrofluorocarbon (HFC) retrofit alternative for R-22 in direct expansion (DX) stationary air conditioning (AC) and medium-temperature commercial refrigeration systems. Because Ametron®  Refrigerants R-417A is compatible with mineral (MO), alkylbenzene (AB), and polyolester (POE) oils—most retrofits do not require a lubricant change. Therefore, retrofitting DX stationary AC and medium-temperature commercial refrigeration systems from R-22 takes considerably less time and investment.

Applications for Ametron®  Refrigerants R-417A include residential and commercial AC systems and medium-temperature refrigeration units, like food service, storage and processing, and supermarket cases
