Zinc Anodes for Seawater Cooling Water Systems are sacrificial (galvanic) anodes specifically designed to provide cathodic protection (CP) for equipment exposed to circulating seawater. These systems include heat exchangers, condensers, pipelines, sea chests, and cooling circuits, which are highly susceptible to corrosion due to continuous exposure to oxygenated seawater.
