American chemical giant Chemours announced Thursday that it will discontinue all domestic sales of two of its refrigerant products – Freon™ 404A (ASHRAE designation R-404A) and Freon 507™ (ASHRAE designation R-507) – citing strategic alignment with regulatory phasedown requirements as its reason for doing so. The announcement marks one of the more high-profile developments at the supplier level, especially for R-404A, a longtime mainstay of the commercial refrigeration industry, as the heating and cooling sector continues to act in response to by HFC regulation.
"This decision supports our commitment to creating a better world through the power of our chemistry, advancing decarbonization, circularity, and socioeconomic value through greener solutions industrywide,” said Doug Westerhoff, Americas Sales Director of Thermal & Specialized Solutions at Chemours in a press release published May 2nd. "The U.S. AIM Act outlines an ambitious phasedown program that demands a significant reduction in HFC sales and consumption with a targeted 40% phase down by 2024. This target helped shape the timing of our announcement, and we are confident this decision will contribute significantly to our customers meeting their sustainability targets."
The press release went on to tout Chemours’ Opteon™ XP40 (ASHRAE designation R-449A) as a viable replacement for existing 404A and 507 equipment. However, like R-404A, R-449A contains an HFC ingredient, and its global warming potential (GWP) of roughly 1400 means that sales of it too will likely be discontinued in the future. Being such, the press release proposed R-454A and R-454C (tradenames Opteon XL40 and XL20, respectively) as longer term, regulation-compliant alternatives for new equipment.
Chemours’ announcement is the latest in a string of industry developments triggered by The American Innovation and Manufacturing (AIM) Act, which was signed into law in late 2020. Around the beginning of the decade, Japanese HVAC conglomerate Daikin announced plans to move new build high-temp HVAC equipment in the US to its patented R-32 refrigerant, with Trane and Carrier choosing Chemours’ Opteon XL41 (R-454B) for the same market.
