R404A Applications
R404A is essential for maintaining commercial refrigeration equipment across the UK. Typical applications include supermarket and convenience store display cabinets, walk-in cold rooms, industrial blast freezers, refrigerated transport vehicles and food processing plant. Its non-flammable (A1) rating and good capacity at low temperatures made it the dominant commercial refrigeration fluid from the late 1990s through the 2010s.
F-Gas Status and Alternatives
R404A has a GWP of 3,922 — one of the highest of any commonly used refrigerant — placing it under significant pressure under UK F-Gas phase-down regulations. New commercial refrigeration equipment now uses lower-GWP alternatives including R448A, R449A, R452A and R407F. However, the very large installed base of R404A systems will require service gas for many years. Refrigerant Gas Supplies Ltd maintains compliant R404A stock for service engineers.
