R-404AT is a “near-azeotropic” HFC mixture derived from the recovery and regeneration of R-404A.
It is authorised for use until 1 January 2030 and will allow the maintenance of equipment originally using virgin R-404A, which is prohibited for use after 1 January 2020.

It is used in installations such as central refrigeration units for large retail outlets (supermarkets and hypermarkets), cold stores, food freezing installations and furniture for the conservation of frozen food and refrigerated trucks.
