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. After the water evaporates, dissolved minerals are left behind and accumulate rapidly until the mineral come out of solution (known as scale).
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:
• Limescale and other water mineral deposits
• Corrosion of all types
• Micro-biological growth, such as algae, bacteria, fungus, and molds
• 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.
