GalVan-Plus is designed to safely remove lime deposits or water scale from cooling towers (basin), water lines and galvanized pipe fittings where stronger, acid-based descalers would degrade the metal. It is most effec-tively used by circulating through the equipment that needs cleaning, providing that there is adequate venting for the carbon dioxide created in the cleaning process. One gallon of GalVan-Plus will consume 1.1 pounds of Calcium Carbonate (CaCO3).
