After extensive tests and evaluation, Carrier has identified R454B, to be known commercially as Puron Advance, as its primary lower global warming potential (GWP) solution to replace R410A in all of its ducted residential and light commercial packaged solutions sold in North America. The new refrigerant, to be offered in these Carrier products beginning in 2023, is expected to surpass the requirements of anticipated future regulations. Carrier will select the best-suited refrigerant for other applications as the need arises.
Carrier has been working with Chemours who will produce and distribute the new refrigerant in North America. With a GWP of 466, one-fifth that of R410A, Puron Advance refrigerant was selected as the best solution to minimize environmental impact and energy use, while improving performance, safety, and longevity, based on the United Nations Montreal Protocol Kigali Agreement phase down plan for hydrofluorocarbons (HFCs). Carrier has worked closely with regulators and research groups to develop standards, codes and regulations that will help ensure the safe use of R454B.
“The move to Puron Advance refrigerant is the next logical step in the evolution of our industry,” said Matthew Pine, president, Residential HVAC, Carrier.
