Impressed Current System long-term solution to corrosion problems, and are recognized as a superior alternative to sacrificial anode systems, which require frequent replacement. Impressed current cathodic protection systems are preferred by ship owners because they reduce fuel cost and maintenance. Systems work by supplying a controlled amount of DC current to submerged surfaces using highly reliable mixed metal oxide anodes and zinc reference electrodes. This electrical current is constantly monitored and regulated by the system itself to prevent the electrochemical action of galvanic corrosion before it begins.
- Increased life of rudders, shafts, struts and propellers as well as any other underwater parts affected by electrolysis.
- Anodes are light, sturdy and compact for easy shipping, storage and installation
- Anodes, reference cells and automatic control systems maintain just the right amount of protection for underwater hulls and fittings, unlike standard zinc anodes, which can’t adjust to changes in salinity or compensate for extreme paint loss.
- Automatic control equipment ensures reliable, simple operation.
- Optimum documented corrosion protection at the minimum overall cost.
- Only one installation required for the life of the vessel or structure.
- Increased dry-dock interval.
