Aluminum Tank Anode with Crancked Rod Insert
The ship’s ballast water tank is subject to galvanic corrosion, especially its internal steel structure immersed in seawater. The only way of preventing corrosion in ballast tank, when coatings become damaged or ultimately break down, is to apply sacrificial anodes.
This aluminum tank anode with double cranked rod core is the most common anode types applied in cathodic protection of vessel’s tank. It is suitable for new vessels, or used to replace existing anodes in old vessels.

Low Driving Voltage
This aluminium tank anode provides a stable performance in seawater and electrolytes containing chloride ions as its operating potential is kept between -1.05 to -1.10 volts relative to saturated calomel electrode(SCE).
| Technical Measurement | Performance |
| Open Circuit Voltage (-V) | 1.10 min. |
| Closed Circuit Voltage (-V) | 1.05 min. |
| Current Capacity | 1135 A.h/lbs (2500 A.h/kg) |
| Current Efficiency | 90% min. |
| Consumption Rate | 7.6 lbs/A·y (3.4 kg/A·y) |
Much Lighter in Weight
The aluminium tank anode is less dense than zinc, making it lighter and easier for handling when fitting.
