The F-gas regulation strongly restricts the use of refrigerants with a global warming potential (GWP) of more than 2500. This includes the R-404A refrigerant used in refrigeration dryers. Beginning on 1 January 2020, fresh material is banned from use when servicing refrigeration dryers with filling volumes above 10.2 kg. From 1 January 2030, its use will be prohibited completely.
Major refrigerant manufacturers have responded and already stopped providing fresh material. Hence, the availability for repairing smaller refrigeration dryers is no longer assured. There are replacement refrigerants for R-404A, however, their individual GWPs are also quite high, hence, they don’t represent a feasible alternative. As well, their use could mean increased structural effort.
We recommend a timely replacement of older equipment instead of their conversion to replacement refrigerants. We discourage the purchase of new refrigeration dryers with R404A refrigerant. Please consult with KAESER and have a look at our solutions.
