200 DUTCH SUPERMARKETS REPLACING HIGH GWP HFC BLENDS BY LOWER GWP ONE

Following trials to replace high GWP blends R-404A and R-507 (GWP of respectively 3,922 and 3,985) which showed that R-449A (GWP of 1,397, or 65% lower) was an energy efficient alternative, a Dutch retail group has converted 200 of its supermarkets to R-449A.

R-449A, a blend of HFC-32 /HFC-125 /HFO-1234yf /HFC-134a, 24.3/24.7/25.3/25.7 % by weight, is considered to be a suitable alternative in new and existing commercial medium and low temperature refrigeration systems.

The conversion was part of the groups target to reduce its environmental impact by reducing its overall emissions, from refrigerant leaks and from those related to the energy consumption from refrigeration systems.
