Refurbishment cooling towers
Europe’s largest software company near Walldorf operates the central ROT07 combined heat and power plant at its St. Leon-Rot site to generate electricity, heating and air-conditioning chilled water. In addition to the various heat generation plants, cooling generation plants are also installed.
6 open cooling towers were replaced with new units with a total cooling capacity of 10 MW and the heat generation and cooling systems were refurbished. Peripheral plant components were also adapted and renewed and the new cooling tower system was connected to the existing re-cooling system. For the correct water volume distribution to the drycoolers, new throttle valves were installed and the steel substructure was completely replaced and built up according to the static requirements of the new drycoolers.
