For a customer in the food industry it has been our task to plan, manufacture and assembly a both ecologically and economically optimized cooling unit. The new unit operates with significantly less amounts of fluorocarbon. Instead, cold water (+6/+12°C) and brine (-12 /-6°C) are used. Thanks to optimised planning, the new cooling unit can also be operated with a significantly reduced number of pumps.
In order to lower operating costs, a reduction of almost 20 pumps was achieved and in addition the quantity of smaller plant components was lowered. During assembly, the cooling towers and the refrigeration machine are set up first. Then, the piping, with the installation of 15 pumps, over 400 fittings and two hydraulic switches with a storage capacity of 3 m3 each follows, as well as two cooling water tanks with a storage capacity of 17 m3 each – built from stainless steel with pipe dimensions of DN 15 to DN 500. The secondary steel construction for the support structures, with a total weight of 28 tonnes, was also designed by us. In the hall of the central cooling unit alone, 1,200 m of piping are connected using more than 2,000 welded joints.
