Anodes of pure copper are mounted under the box cooler in the sea chest. A constant current is applied between the anodes and the sea chest, which caused copper to dissolve in the sea-water. These CU ions create a continues toxic environment for biological growth, preventing the attachment and growth of marine organisms.
These anodes are to be mounted directly under the box cooler. In case of separate anodes the supports for the anodes are welded onto the sea chest. (See picture.)
Alternatively the anode system can be integrated into the box cooler. With these integrated anodes - see figure - the cabling is fed through the box cooler to ease installation. The extra weight of the anode-rack does not influence the mechanical stability of the cooler, even under heavy seagoing conditions.
Retrofitting an ICAF system
In case the thermal performance of a box cooler has deteriorated, due to marine growth, retrofitting an ICAF system is possible in most cases. Contact GEA Bloksma in case retrofitting is considered.
