TP24-12 Development of a Novel Non-Azole-Containing Cooling Water Treatment ProgramSince the introduction of phosphate to replace chromate based cooling water treatment programs, azoles have been widely used to inhibit corrosion of copper and copper alloy heat exchangers, and to prevent galvanic attack on mild steel components. Some azoles and the films they produce are not stable in the presence of oxidizers, such as sodium hypochlorite, which significantly reduces the level of protection they offer. Moreover, azoles also have a

At the time we were certainly aware of the control without forming phosphate deposits on hot bundles problems with admiralty brass corrosion using only azoles
