What type of water treatment do you recommend for an open-loop cooling system?

Because evaporative towers scrub the air that passes through them, they are prone to collecting debris from the air. This debris can accumulate and cause flow restrictions; as well as aggravate corrosion. Also, after the water evaporates, dissolved minerals are left behind and accumulate rapidly. For these reasons, a properly engineered and administered water treatment program must be employed continuously with the cooling tower.

In an open tower cooling system, the water quality must be regularly monitored and treated to control the following conditions:

  1. Lime scale and other water mineral deposits
  2. Corrosion of all types
  3. Micro-biological growth, such as algae, bacteria, fungus and molds
  4. Suspended solids accumulations, such as airborne dirt and debris that is washed into the cooling tower water.

Dry Coolers recommends consulting a local water treatment supplier (Calgon, Nalco, Culligan, etc.) that is familiar with your local water quality to monitor your treatment program.
