Introduction:
Freon R-422B refrigerant is a low-toxicity, non-ozone depleting hydrofluorocarbon (HFC) replacement for R-22. It consists of R125-56%,R134A-42.5% and R600a-1.5%.
The industry-wide phaseout of R-22 to meet mandates to reduce high ozone-depleting potential (ODP) refrigerants depends on alternative options such as R-422B.
This nonflammable HFC alternative offers a host of benefits that include:
