Product Overview
R-422B is a non-ozone-depleting refrigerant compatible with all standard oils, equipment components, and materials used in R-22 systems. R-22 systems that convert to R-422B see a minimal capacity loss of less than 10%.
- No oil change on R-22 retrofit refrigerants
- For residential AC systems and applications
- The hydrocarbon component in R422B helps promote oil return in systems containing mineral oil or alkylbenzene.
- Thousands of successful global retrofits for the past decade
