Carrier chooses Opteon XL41 to replace R410A

R454B, Chemours' next-generation refrigerant sold as Opteon XL41, has been selected by Carrier as the primary lower global warming potential (GWP) refrigerant to replace R410A in ducted residential and light commercial packaged products sold by the firm in North America, beginning in 2023.

The selection of R454B is expected to enable Carrier to achieve its exacting performance standards, while exceeding the anticipated requirements of future regulations. With a GWP of 466, Opteon XL41 reduces CO2 emissions by 78 percent and improves energy efficiency when compared to R410A, while providing over 30 percent reduction in GWP when compared to R32, another industry candidate to replace R410A.

Opteon XL41 was specifically developed to achieve the maximum possible reduction in GWP to satisfy long-term regulatory requirements. 

“As the world moves towards more environmentally sustainable solutions, equipment manufacturers are searching for lower GWP options that will meet future regulations and can deliver on performance. Opteon XL41 achieves just that,” said Diego Boeri, vice president of Chemours Fluorochemicals. “We are thrilled to work in collaboration with Carrier to bring about transformative change for the air conditioning industry. Chemours is committed to delivering world-class technology through responsible chemistry that reduces impact on global climate change.”

Opteon XL41 is an ASHRAE Class A2L (lower flammability), hydrofluoro-olefin-based refrigerant and was chosen by Carrier for its balance of performance, energy use and safety, combined with the longevity and peace of mind it offers customers as a low GWP replacement for R410A.

Carrier will market R454B as Puron Advance across North America. 

“Carrier is committed to the environment by providing efficient, responsible solutions to its customers. The move to Puron Advance refrigerant is the next logical step in the evolution of our industry,” said Matthew Pine, president, Residential HVAC, Carrier. “We carefully studied the alternatives and chose the most viable refrigerant with the lowest environmental impact for our product application. Innovation and technological advancement are in our DNA and we will continue to lead the way with the evolution of refrigerants of the future.”
