Development of a closed loop cooling system for a Swiss chemical company


Helbling Beratung + Bauplanung conducted a study to develop new solutions to replace the open loop cooling system using river water with a closed loop system. New systems with a max. cooling power of 2.5 MW were analysed economically, energetically and technically to allow a comprehensive comparison and to find the best solution. In addition, the concepts were optimised by using historical site measurements and weather data. The optimised concepts showed significant cost savings by reducing the energy and water consumption. The results of the preliminary and basic study (including basic engineering) includes all the necessary information for the next step towards realisation of the project.
