Seafood processor switches to natural cooling

Part of Young’s Seafood, Scottish smoked salmon processor Pinneys has switched to a natural ammonia cooling system from Star Refrigeration at its facility in Scotland, UK.

Until recently, the majority of the firm’s cooling systems for chilling, freezing and cold storage operated with synthetic refrigerant R22, which has been gradually phased out by EU directives and became subject to a ban in Europe from January 2015. Pinneys approached Star Refrigeration to provide support in developing an R22 phase out strategy.

Star designed and installed an Azanefreezer system, an air-cooled, ammonia refrigeration plant for cold storage applications. Azanefreezer operates with a low charge of natural refrigerant ammonia and features Star’s low pressure receiver and EC condenser fan control technology. The system delivers efficiencies up to 20 per cent higher than a traditional HFC refrigeration system.
