How the Cathelco system operates The Cathelco system has proved to be an extremely effective and versatile system for eliminating blockages in seawater pipework caused by biofouling. The system is based on the electrolytic principle and usually consists of pairs of copper and aluminium anodes which are mounted in seachests or strainers and wired to a control panel. In the case of cupro-nickel pipework, a ferrous anode is used instead of the aluminium anode. In operation, the copper anode produces ions which are carried by the flow of seawater, creating an environment in which barnacles and...

Systems for smaller vessels By miniaturising control panels and anodes, Cathelco have brought the benefits of pipework anti-fouling technology to a wide variety of smaller craft including offshore supply vessels, workboats, small ferries and tugs. Many of these vessels operate continuously within in-shore waters where there is a much higher risk of bio-fouling. By fitting a Cathelco system and eliminating problems of blockages in seawater lines serving engine cooling systems, considerable savings can be made in fuel usage and maintenance costs. Nano Systems This system represents the...
