Which ISCEON™ refrigerant is right for you?

Freon™ MO59 refrigerant
AC Conversion Made Simple

Freon™ MO59 was one of the earliest R-22 replacement refrigerants on the market and continues to be used effectively in some applications, such as AC conversions.

Note: If you are looking for a retrofit refrigerant that can be used for low, medium, and high temperatures, please consider Freon™ MO99.

Freon™ MO59 (R-417A) is a non-ozone-depleting HFC retrofit refrigerant blend, typically used in AC conversions to replace R-22 in direct expansion stationary air conditioning and medium-temperature refrigeration systems. Freon™ MO59 has a significantly lower discharge temperature than R-22, which may prolong the life of the compressor.

In some systems, Freon™ MO59 provides the required cooling capacity. However, after some AC conversions, the system will likely experience reduced capacity greater than 15%.  For a closer match to R-22, consider using Freon™ MO99.
