CW-7 Scale and Corrosion Inhibitor is designed for systems using makeup water of high hardness and alkalinity and discharging to a city sewer or other water treatment plant. It is controlled by a molybdate test which provides easy and accurate control readings. This product is USDA G7. Although the name “cooling tower treatment” is familiar, we could better call these products “heat exchanger treatment.” WTW products are formulated to provide scale and corrosion control in a wide range of field conditions and especially at the heat exchange area where efficiency is gained or lost. |
