Natural cooling for coldstore

Pinneys approached cooling expert Star Refrigeration to provide support in developing an R22 phase out strategy. This involved reviewing all multi-temperature cooling systems on site and assessing alternative solutions, including retrofit gases, installing new HFC refrigeration equipment and switching to natural refrigerants.

Star designed and installed an Azanefreezer system, an air-cooled, ammonia refrigeration plant for cold storage applications. Azanefreezer operates with a very low charge of natural refrigerant ammonia and features Star’s low pressure receiver and high efficiency EC condenser fan control technology.
