In the beginning of this year an installation of a modern energy saving cooling system by Reisner has been finished. This system cools the moulds and hydraulic system and uses the waste warmth to heat the factory buildings. The Epsilon installation with 3 turbocompressors with the power of 900 kW is the heart of the system. There are also two new dry coolers that support the system. Such a compilation makes the system very flexible. Extended control system ensures the proper functionality of all the system installations. The system has been equipped with two containers for dosing the biocides and anticorrosives. Full stream filters Reisner BO-X installed in the return path eliminate all the impurities from the water.
