Freon M059 R-417A Refrigerant Gas 25lb / 11.9 kg US Origin Chemours ISCEON MO59 (R417A) is an HFC retrofit refrigerant that is cost-effective and ozone-friendly, used to retrofit equipment that uses R22, such as air conditioning (AC) and medium-temperature commercial refrigeration systems. Applications: Residential and commercial air conditioning systems. Note: For water-cooled systems, MO29 is recommended. Medium temperature refrigeration, commonly used in commercial units, including food service, supermarket display cases, and food storage/processing. Benefits: Efficient and cost-effective retrofits. Ozone-friendly, does not harm the ozone layer. In most cases, no need to change lubricant type during the retrofit process; compatible with traditional and new lubricants. No need to replace existing equipment. After the retrofit, MO59 can be topped off without needing to drain the refrigerant. Advantages: Lower discharge temperatures compared to R22, which can extend compressor life. Provides the necessary cooling capacity in most systems. Proven to save energy in some systems. MO59 is an ozone-depleting substance (ODS) with zero ODP (Ozone Depletion Potential) and is not subject to phase-out under Montreal Protocol regulations. Recommended lubricants: Mineral Oil (MO), Alkylbenzene (AB), and Polyol Ester (POE) in most cases, no lubricant change is required during the retrofit process.
