One of the most common refrigerants used by fish and seafood processors, R22, is being phased out under European legislation.

The clamp-down covers HCFC compounds, which are harmful to the ozone layer when released to the environment. One of the most important refrigerants affected is R22, widely used in refrigeration systems in food and drink manufacture for process cooling, ice production, blast and spiral freezing, storage and transport. The regulation also affects HCFC-containing refrigerant blends such as R401A, R402A, R403B, R408A and R409A.
