Cooling water

Cooling systems are divided into three types:

  • Once-through systems
  • Closed loop systems 
  • Open loop systems

Open loop systems are the most widely used system and examples of this are cooling towers and evaporative condensers. At the same time, water treatment is most prevalent in connection with open loop systems. Water treatment is carried out in order to minimize scaling and deposits, fouling, corrosion, and biological growth.

Complete solutions
An optimum cooling water solution is achieved by continous drainage of correct water volume, softening of make-up water, partial stream filtration, and correct dosing of polyphosphate and hypochlorite respectively. EUROWATER is in a position to deliver complete solutions for your task.

Optimum economy
A correct treatment of cooling water gives optimum service conditions and extends the life of the cooling system significantly. EUROWATER has wide experience in supplying reliable and safe solutions to achieve efficient cooling water systems.
