Daikin’s non-ozone depleting, GWP 1495, non-flammable refrigerant R-407H compares favorably to R-404A which is commonly used today. Daikin R-407H achieves a COP of 106% when compared to R-404A in Medium and Low Temperature refrigeration applications while providing a near perfect match to R-404A pressure. R-407H has been classified by ASHRAE as safety group A1, and is compatible with common POE oils. Additional performance details, test results, case studies and compatibility information and commercial samples are available upon request.
