The Chemours Co. has announced that the U.S. Environmental Protection Agency (EPA) through its Significant New Alternatives Policy (SNAP) program, has listed the low global-warming potential (GWP) refrigerant Opteon™ XP44 (R-452A) as acceptable for use in new and retrofit equipment for refrigerated transport and remote condensing units used in retail food refrigeration.

According to Chemours, R-452A has a GWP approximately 50 percent lower than R-404A, and was specifically designed for applications where low compressor discharge temperatures are required. It provides a closes discharge temperature match to R-404A, which makes it well-suited as a replacement for R-404A in applications such as transport refrigeration and hermetic compressor systems, especially in low temperature conditions.

In addition, Chemours announced expanded approvals for Opteon XP40 (R-449A) and Opteon XP10 (R-513A).

● The approval for Opteon XP40 (R-449A) has expanded to include use in new and retrofit cold storage warehouse and industrial process refrigeration equipment. The EPA previously had listed R-449A as an acceptable refrigerant in several commercial and retail food refrigeration applications. According to Chemours, R-449A provides equipment owners and contractors with a solution to replace R-22 or R-404A in retrofits or new equipment, with up to 12 percent improvement in energy efficiency and a 67 percent lower GWP than R-404A. The company said R-449A has been tested and approved by major equipment manufacturers and is being widely used in thousands of systems globally. It is nonflammable.

● The approval for Opteon XP10 (R-513A) has been expanded to include use in new and retrofit residential dehumidifiers.R-513A is already acceptable for use in numerous applications, including chiller and retail food refrigeration applications. According to Chemours, as an azeotropic, non-flammable replacement for HFC-134a, Opteon™ XP10, offers a 55 percent reduction in GWP compared to HFC-134a, while also maintaining comparable properties and performance. The company said several major global chiller manufacturers have announced equipment designed for R-513A, and OEMs and retailers in the commercial refrigeration space have begun to adopt it as well.

“Our customers require us to be on the cutting edge of new technology so that they can meet the evolving challenges they face,” said Diego Boeri, vice president, Chemours Fluorochemicals. “These new EPA SNAP listings ensure that low GWP refrigerants by Chemours are available for applications our customers need.”
