Daikin America Inc., a subsidiary of Daikin Industries Ltd., recently announced the availability of R-407H refrigerant for research-and-development and test-marketing samples in the United States.
Samples are intended for refrigeration contractors and distributors working on supermarkets, grocery stores, walk-in coolers and freezers, and mini grocers. Samples are applicable to OEM systems and R-404A and R-22 retrofits. For specific guidance, reach out to equipment manufacturers.
Officially launched on March 8, 2017, Daikin R-407H has been submitted to the U.S. Environmental Protection Agency's (EPA's) Significant New Alternatives Policy (SNAP) program as a replacement for the legacy ozone-depleting refrigerant R-22 and high-global-warming-potential (GWP) refrigerants such as R-404A and R-507A, which are widely used for supermarket, warehouse, and marine-vessel refrigeration equipment.
“Due to increased regulations, high-GWP and ozone-depleting refrigerants such as R-22 are being phased out," Jim McAliney, executive vice president, sales and marketing, Daikin America, said. "Daikin’s 407H was developed to comply to global regulations while allowing for simple and economical retrofits. Additionally, Daikin’s 407H proven track record and efficiency is uniquely positioned to achieve EPA’s GWP targets.”
Non-ozone-depleting, GWP-1495, and non-flammable R-407H compares favorably to R-404A, which is commonly used today. R-407H has been classified by ASHRAE as safety group A1 and is compatible with common POE oils. Performance details, test results, case studies, and compatibility information are available on request.
