Low Driving Voltage
This stand-off aluminium 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 stand-off aluminium anode is less dense than zinc, making it lighter and easier for handling when fitting.
Customized Configurations
Our slender stand-off aluminium anodes are further classified into Short and Long, depending on their ratio of length to width. The length affects the resistivity of the anode and thus its current capacity.
