Honeywell’s Solstice® N40 (R-448A) refrigerant has been approved for use by the U.S. Environmental Protection Agency (EPA) in applications ranging from stand-alone refrigeration systems to commercial refrigeration. The EPA also broadened approvals for the company’s Solstice N13 (R-450A) refrigerant, allowing it to be used in retrofit vending machine applications. The EPA approved the new refrigerant uses under its Significant New Alternatives Policy (SNAP), which evaluates substitute chemicals and technologies that are safe for the ozone layer. The final rule will be published in the Federal Register in the coming weeks.
“Honeywell has been steadily broadening its range of reduced and low-global-warming replacements for high-global-warming hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs), helping customers around the world decrease their global warming footprint and comply with new regulation,” said George Koutsaftes, refrigerants business director for Honeywell Fluorine Products. “Solstice N40, Solstice N13 and the entire range of Solstice stationary and mobile refrigerants help customers achieve their environmental goals without sacrificing performance.”
Global regulators are increasingly moving to phase out high-global warming refrigerants and, on July 2, the EPA announced landmark regulations that will phase out the use of many of the world’s most potent HFCs, such as R-404A, in a variety of applications. The new regulation effective summer 2016 will require supermarkets, the largest consumers of R-404A in the U.S., to discontinue use of R-404A as a retrofit refrigerant. R-404A will also not be permitted for use in new supermarkets beginning January 1, 2017.
