Freon™ 236fa (R-236fa) Refrigerant

A Nonflammable Retrofit Refrigerant for R-114

Freon™ 236fa (R-236fa) refrigerant is a hydrofluorocarbon (HFC) retrofit option for R-114. It is used in:

  • Low-pressure and existing centrifugal chillers
  • Industrial process refrigeration systems
  • High-ambient cooling applications (e.g., overhead cranes)

Most original equipment manufacturers (OEMs) recommend using polyolester (POE) lubricant when retrofitting to R-236fa, which also extends system life. Retrofitted centrifugal chillers may require system modifications as well as a change in lubrication. Consult your OEM for specific details.

Features and Benefits

Replacing R-114 with Freon™ 236fa in chillers offers a number of benefits, including:

  • Zero ozone depletion potential (ODP)
  • Extended life of R-114 chillers
  • An ASHRAE A1 safety classification
