Rectifier/Control Panel

Available in sizes from 50 amps to 1,200 amps with a digital display showing the output to each anode. Can incorporate over/under protection alarms and be wired to the main on-board computer, if required.

Reference electrodes

These are flush mounted on the hull and measure the electrical potential at the hull/seawater interface. A signal is fed to the control panel which increases or decreases the anode output accordingly.

Permanent Anodes

Linear anodes are mounted on the surface of the hull, whilst circular anodes can be recessed to minimise drag. The current emitting faces are made from mixed metal oxide (MMO).
