General Principles

The Cathelco System is based on the electrolytic principle and consists of a control panel which can be fed with a d.c. current of between 12V and 24V or 110/220V a.c. This is wired to a copper anode which can be fitted in the craft's strainer or seawater inlet. Two types of anodes are available for use with the systems:-

• Copper anodes to protect steel, stainless steel or copper alloy strainers and pipework against bio-fouling.
• Copper anodes with integral cathodes to protect plastic strainers and pipework.

In operation, the system feeds an impressed electrical current to the anode which produces copper ions. As the ions spread throughout the pipework system they create an environment where marine crustacea such as barnacles and mussels cannot settle or breed, but are immediately passed to discharge.

Design & Installation

Each system is custom designed for its application taking into account flow rates, anode life and drydocking intervals. A detailed Technical Manual is provided covering all aspects of the installation of the system.
