TECHNOLOGY IN HARMONY WITH PHYSICS AND THE ENVIRONMENT Physical make-up water treatment for evaporating cooling towers is standard in more than 3500 plants in Europe. It is chemical free, saves costs, environmentally safe and pollution free. Easily installed on the water supply inlet and effective in preventing deposits, it is the future alternative to avoid chemicals in cooling tower water circuits.

AC6 1 1/2" supply water

Cooling tower coils

The problem: 50% closed coils by lime scale deposits in a cooling tower in spite of costly chemical dosages.  Poor cooling, high compressor energy, and pollution.  Water hardness: 20 degree = 380 PPM The solution: Cooling tower: 1 1/2" conditioner on the supply water.  Up-concentration of mineral salt automatically controlled by water conductivity measurement. Discontinued use of chemicals (only pure water treatment). The results: Within a few days solid deposits were dissolved and after 3 months fully removed from the coils.  Economical advantages: all chemical cost saved, less compressor energy by better heat exchange, and a total pollution free treatment.
