Antifouling anodes in strainers
Does your antifouling system need a boost without entering dry-dock? Cathwell mud box anodes can be retrofitted while at sea.
Strainer mounted antifouling anodes can be replaced during operation.
When MGPS/ICAF antifouling is installed in brand new vessels, the anodes should preferably be mounted in the sea chests. This in order to treat the water already before entering the seawater pipe works.
MGPS/ICAF anodes in strainers have the advantage that they can be installed and replaced without having to enter dry-dock.
Antifouling boost effect
MGPS/ICAF antifouling anodes can be fitted in the seawater strainers/mud boxes, and eventually in cross-over tanks. The anodes come with specially adapted cofferdams for installation in the strainer lid. The anodes can either be energised by an existing control panel or by a new CathFlow® panel.
Benefits: The antifouling anodes are easy to install in the filter house lid when anode renewal becomes necessary, independently of dry-docking.
Design life time. Typical design life time of the anodes are 1 to 2 years, mainly depending on the seawater flow.

The anodes are bolted through the mud box lid to a cofferdam made of POM (polyoxymethylene). In some cases new lids have to prefabricated in order to enable installation of the anodes.
The arrangement is compatible with most filters. In order to avoid harmful stray currents, the filter has to be properly connected with the strainer/mud box body. In strainers with non-metallic filters, a separate cathode may be required.
Cathwell co-operates with John Gjerde AS for hi-end welded plate and custom-made filters up to DN 1000.
