Daikin’s R-407H has been submitted for EPA SNAP approval as a replacement for R-22, R-404A, and R-507A. Daikin America Inc., a subsidiary of Daikin Industries, announced the availability of R-407H refrigerant for research and development, and test marketing samples in the United States.
Samples are applicable to OEM systems and R-404A and R-22 retrofits. Contractors and distributors should reach out to equipment manufacturers for specific guidance. This follows the official product launch of Daikin R-407H on March 8.
Daikin R-407H has been submitted for approval to the EPA SNAP Program as a replacement for the legacy ozone-depleting refrigerant R-22, and high global warming potential refrigerants such as R-404A and R-507A, which are widely used today 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,” stated Jim McAliney, executive vice president of sales and marketing, Daikin America. “Daikin’s 407H was developed to comply to global regulations while allowing for simple and economical retrofits.”
Daikin’s nonozone-depleting, GWP 1495, non-flammable refrigerant R-407H compares favourably to R-404A, which is commonly used today. You can view a comparison of the two here. R-407H has been classified by ASHRAE as safety group A1, and is compatible with common POE oils.
