Optimization of theCentral Cooling Supply Systemat Gascogne Laminates Germany GmbH

Key Technical Data:
  • Total Cooling Capacity: approx. 700 kW 
  • Energy Efficiency Ratio: (EER) 5-12
  • Electrical energy savings: up to 85% compared to the existing system
  • CO2-reduction: 823 t/a
  • Environmentally friendly operation: with R1234ze low-GWP refrigerant

As part of a comprehensive modernization project aimed at improving energy efficiency and operational reliability, RheinEnergie AG commissioned the upgrade of the central cooling system at Gascogne Laminates Germany GmbH. The core of the new installation is a highly efficient centrifugal chiller with an integrated free-cooling system, housed in a containerized plant (ChillCon) located outdoors.

The new cooling system ensures a sustainable, flexible, and future-proof cooling supply for all production areas while significantly reducing energy consumption and CO₂ emissions.

Key Project Measures

  • Construction of a centralized cooling system in an external ChillCon containerized plant, including a gas detection system, emergency ventilation in accordance with DIN 378, and an outdoor dry cooler.
  • Installation of a turbo chiller featuring magnetically levitated compressor shafts and a cooling capacity of approximately 2 × 350 kW (Quantum technology).
  • Combined use of the dry cooler as a free-cooling system, utilizing low ambient temperatures to provide cooling without mechanical refrigeration.
  • Automatic switching between operating modes to optimize energy consumption and system efficiency.
  • Energy-efficient pump control using variable frequency drives (VFDs).
  • Conversion of the entire production cooling system from an open-loop to a closed-loop circuit, including cleaning of the complete customer-side piping network.
  • Low-wear technology with minimal maintenance requirements and a centralized control system.
