For over 50 years, factory assembled cooling towers, evaporative condensers, closed circuit cooling towers and other evaporative cooling products have been manufactured from hot-dip galvanized steel. The life expectancy of these units, when properly installed and maintained has been excellent, often exceeding 20 years. In recent years, however, there have been reports of installations experiencing premature attack from “white rust”. The critical fact that needs to be recognized is that white rust is preventable.
For more information on white rust including the causes, prevention, removal and treatment, view the new technical resource document in the Knowledge Center.
