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
The slender stand-off anodes are further classified into Short and Long, depending on their ratio of length to width. A range of standard stand-off anodes are illustrated below, custom-made configurations are available upon request.
