Freon 23(R-23) Refrigerant

A Retrofit Refrigerant for Very Low Temperature Equipment

Quick Contact us, we are here to help you

The Freon refrigerant portfolio includes Freon 23 (R-23) refrigerant for equipment that needs to maintain very low temperatures (VLT), such as medical freezers and environmental chambers. This hydrofluorocarbon (HFC) retrofit refrigerant is an effective alternative to R-13 and R-503 when temperatures must remain at or below -40 to -73 °C (-40 to -100 °F). Most original equipment manufacturers (OEMs) of systems using R-23 recommend using polyolester (POE) oils. Consult your OEM to determine whether your system requires an oil change or any other system modifications.

Features and Benefits

Freon 23 also works when retrofitting existing systems that use R-13 and R-503, sometimes with slight system modifications required. Freon 23 is a nonflammable refrigerant that works well in applications where a high compressor discharge temperature is not a concern.
