Getting the best out of A2L refrigerants in Commercial Refrigeration applications

The ban on the use of R-404A and other >2500 GWP refrigerants for both new install and service in most commercial refrigeration applications has been in place for more than 18 months. This ban, together with price and availability issues brought about by the phasedown in CO2 equivalent quota, has placed more focus on what should be installed today to remain sustainable past 2030. Mid-range GWP blends such as Opteon™ XP40 (R-449A) are now well established for retrofit and can be used for new equipment in the interim but the GWP is just too high for the longer term.
