CAPAC® Permanent Corrosion Protection
Consistently automatic, long-lasting hull protection against electrolysis and galvanic corrosion for various sea-going vessels and offshore structures. In comparison to sacrificial anode systems, these systems offer not only reliable corrosion prevention but also long-term cost savings.
Industry-Standard CAPAC ® Systems: Permanent Corrosion Protection
CAPAC ® ICCP systems consistently provide automatic, long-lasting protection against electrolysis and galvanic corrosion for various sea-going vessels and offshore structures. In comparison to sacrificial anode systems, these systems offer not only reliable corrosion prevention but also long-term cost savings.
Key Components of CAPAC® Systems
The CAPAC® system primarily includes three core components: Controllers, Anodes, and Electrodes, supported by a power supply. These elements work together to deliver superior corrosion protection for ships and offshore platforms.
Benefits of CAPAC® Systems
- Global Leadership: With over 3,000 systems installed worldwide, CAPAC® is widely recognized and approved by all major classification societies for all vessel types.
- Extended Lifespan: Furthermore, the systems are designed to offer a service life exceeding 20 years.
- Simple Operation: Automatic control ensures reliable protection. Compact anodes make shipping and installation easy.
- Increased Lifespan of Components: Rudders, propellers, shafts, and fittings enjoy longer lifespans due to precise control of corrosion protection.
- Reduced Maintenance Costs: Increased drydock intervals and reduced fuel costs through effective corrosion management.
- Trusted by Navies Worldwide: Supplying naval forces for over 50 years.
What is Cathodic Protection?
Cathodic protection, particularly impressed current cathodic protection (ICCP), uses DC current to shield submerged surfaces from corrosion. As a result, it provides continuous, automatic protection, reducing the effects of electrolysis and galvanic corrosion significantly in both mobile and fixed offshore structures.
How ICCP Works
ICCP systems deliver a regulated DC current to submerged surfaces, effectively using zinc electrodes and metal oxide anodes. This system halts the electrochemical process of corrosion before damage occurs, making it a preferred solution for vessels such as LNG carriers, oil tankers, and cruise ships.
Advantages of Evoqua ICCP Systems
- Extended Component Life: Protects shafts, rudders, and other parts from electrolysis.
- Compact Design: Anodes are both lightweight and compact, making storage, shipping and installation simple.
- Reliable Protection: Automatic controls maintain consistent protection, adjusting for salinity and paint loss better than zinc anodes.
- Reduced Costs: Fewer drydocks and lower fuel consumption mean long-term savings.
- Longevity: Designed to last over 20 years with a single installation.
Ultimately, CAPAC® systems offer a proven, effective solution for preventing corrosion, ensuring long-term reliability, cost efficiency, and enhanced protection for vessels and offshore structures.

Corrosion Monitor – CM-2
The Corrosion Monitor CM-2 provides boat owners with continuous insight into the condition of their vessel’s underwater metal parts. It allows you to know at all times whether corrosion is under control, ensuring maximum protection and peace of mind. CM2
The system includes a silver–silver chloride reference electrode with a 2,5-inch diameter screen, supported and electrically insulated from the hull by a black plastic housing. Together with a precision meter that measures the electrical potential between the electrode and the underwater appendages, the system provides accurate, real-time monitoring of galvanic corrosion levels.
Key Benefits and Features
- Instant corrosion visibility: Easily read corrosion protection levels directly on the meter.
- Timely zinc replacement: Instantly know when your zinc anodes are depleted.
- No batteries required: The system operates permanently without external power.
- Maintenance-free design: Built for long-term reliability with no upkeep needed.
- Expandable protection: Easily upgrade to CAPAC® Impressed Current Protection in the future.
- Ideal for leisure boats: Optimized for private vessels and small commercial craft.
- Accurate galvanic corrosion indication: Continuously monitor underwater metal health.
Easy Installation
Installation is simple and efficient. Mount the display at the helm or dashboard, at least three feet away from the magnetic compass and away from direct water spray. Only two wire connections are required. One to the reference electrode and one to the hull fittings.
To install the reference electrode, drill a ½-inch clearance hole through the hull from inside the bilge. Then, follow the seven straightforward steps outlined in the Owner’s Manual (P/N 50186).
