Optimization of theCooling and Heating Supplyat Dekura GmbH

Key Technical Data:
  • 75 % reduction in operating costs for chilled-water production 
  • High energy efficiency through modern cooling and control technology 
  • Sustainable heat utilization through waste-heat recovery 
  • Reduction of the ecological footprint

At Dekura GmbH in Höxter, a leading plastics recycling company, the central cooling and heating supply was comprehensively modernized on behalf of RheinEnergie AG.

The goal was to increase energy efficiency, reduce operating costs, and make better use of existing resources. During ongoing operations, the system was converted to a closed chilled-water network with efficient pump technology and a modern turbo chiller. In addition, measures for waste-heat recovery were implemented.

Key Project Measures

  • Conversion to a closed chilled-water network to reduce pump power
  • Installation of an air-cooled turbo chiller for efficient cooling generation
  • Demand-based pump control to optimize energy usage
  • Integration of a free-cooling circuit to utilize low outdoor temperatures
  • Connection of the existing compressors to a heat storage system to use waste heat for heating and hot-water production
