The delivery of one, also ensuring a significant reduction in products with a long shelf life and the the environmental impact of our production excellent operation as well as nice look processes. When we have had to change of the systems are the leitmotifs of this our coating plant, we sought a solution that industry. could ensure lower energy consumption and Sest Spa is one of the most important the total recovery of the water used. The European manufacturers of evaporators prime contractor of this engineering project, and condensers for refrigerated counters Imel (Codroipo, Udine, Italy), involved one and it is one of the largest producers of of its strategic partners to design a suitable heat exchange finned coils (ref.
