Antifouling Anodes (Copper / Aluminium)

Ships use seawater for several purposes, and one of the primary functions is cooling the engine and parts of the ship while while sailing. However, as the seawater passes through the various pipes and parts to cool the ship’s engine, marine organisms could deposite along their surface.

To protect and purify the surface of ship’s mechanical parts, our electrolytic anti-fouling anodes combo system function as both anti-fouling agent and corrosion inhibitor. The fouling organisms can be inhibited from growing by dosing small quantities of Cu ions into the water with a total anti-fouling effective rate over 95%. And aluminum hydroxide
colloid formed could provide an anti-corrosive film over the sea water piping system – keeping corrosion rate less than 0.03 mm/year.

This anode combo of copper and aluminium anodes provides a simple method of fouling prevention that is fitting marine growth prevention system (MGPS) on board.

Copper anode produces copper ions which are transported by the seawater and carried into the pipework system to prevent marine growth.

Aluminum anode produces aluminum hydroxide which spread throughout the pipe work and produce an anti-corrosive layer on the internal surface of sea water cooling lines.

The size (diameter and length) of the anodes is determined based on seawater velocity (inlet water debit), design life and consideration of the maintenance or dry docking schedule for the vessels. Standard sizes range from 50mm to 150mm in diameter and 100mm to 2,000mm length.
