Features
- R-454B, also known as Opteon XL42, is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in current HVAC manufacturing
- R-454B refrigerant is quickly becoming the HVAC industry standard for use in air conditioners and heat pumps and you can expect to see it increasingly used in newly manufactured units
- R-454B is a blend of R-32, a hydrofluorocarbon (HFC), and R-1234yf a hydrofluoroolefin (HFO). R-454B has a lower GWP than previous refrigerants, meaning it has a much lower climate impact.
- R-454B has no ozone depletion potential (ODP) and has low toxicity
- R-454B GWP is more than 75% lower than its most recent predecessor, R-410A, and surpasses the EPA requirements for low-GWP refrigerant (<700 GWP)
