The German retail network Edeka uses an ammonia refrigeration plant in its new meat processing operations in Mecklenburg-Vorpommern. The two-storey “Nordfrische Center” became necessary when the company decided to expand its production as well as its range. The project was realised by Johnson Controls Systems & Service.
|Demands||A system consisting of refrigeration and deep-freeze rooms that would meet all technical requirements while remaining efficient and inexpensive was needed.
|Solution||Johnson Controls Systems & Service realised a two-stage ammonia system involving screw compressors. It produces refrigeration output of 5,500 kW with a refrigerant charge of 10,000 kg. The evaporators and air coolers were supplied by Güntner, the liquefiers by Evapco. The cooling fluid piped through the processing rooms is ethylene glycol (34 %).
