Daikin’s refrigerant R-407H is a replacement for R-404A in conventional supermarket applications. This year’s strong reduction in F-Gas quota has led to both a massive price increase and a decrease in availability of the high-GWP refrigerant R-404A. Many users need to decide quickly how they want to operate their R-404A systems in the future.

The German supermarket chain Klaas + Kock (K+K) took the initiative in January 2018 and made the switch from R-404A to DAIKIN R-407H in a supermarket in Epe near Gronau (Westfalen).
