System start-up

1992

The meats and sausages producer Herta relies on ammonia refrigeration systems at its original plant in Herten, Westphalia. The numerous refrigerated storage rooms were fitted out by Güntner.

Demands

Herta required high-performance high-bay, short-term and deep-freeze refrigeration facilities to properly store its speciality meat and sausage products.

Solution

The high-bay refrigerated warehouse consists of five refrigerated rooms where uncut and packaged sausage products are stored separately. Refrigeration here is provided by eight Dual Discharge ammonia evaporators. Built by Güntner, they are ceiling-mounted and ensure a constant ambient temperature of 0°C. Each of the 22-kilowatts evaporators has a blowing range of 14 metres on either side, which translates to a circulation volume of 12,600m³/hr. For further energy savings, the waste heat generated during the refrigeration process is used to de-ice the evaporators. In the short-term cold storage room, four ammonia evaporators keep the products at -2°C. The deep-freeze warehouse is equipped with three evaporators and has an ambient temperature of -27°C.
