Further water-treatment technology

  • Use in all cooling systems or for the production of wetting water when using a hybrid dry cooler
  • Water analysis forms the basis for product selection
  • Size depends on the required water volume
  • Examples of use include reverse osmosis plants, deferrisation plants, demanganisation plant

The components, some of which are pre-assembled in the factory, are usually installed individually in the plants in a suitable location; their function is independent of the rest of the cooling system.


Water is a vital part of the entire cooling system as a cooling medium in cooling water circuits. The available input qualities, requirements based on the type of cooling system and the operating conditions can differ greatly.

The system design (type of circuit, materials used) and the operating parameters (temperatures, pressures), the necessary components of an effective water treatment system must be determined based on an analysis of the ingredients of the available water.

Water treatment includes the control and treatment of make-up water and recirculated water. Essential parameters are pH value, carbonate and total hardness, electrical conductivity, and the number of colony-forming units (cfu).
