Low Driving Voltage
This aluminum condenser anode maintains consistent performance in seawater and electrolytes with chloride ions by maintaining its operational potential within the range of -1.05 to -1.10 volts compared to the 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
Due to its lower density compared to zinc, the aluminum condenser anode is lighter, facilitating easier handling during installation.

Strict Quality Control
Adhering to the guidelines set forth by ISO 9001:2015, our aluminum condenser anode undergoes rigorous manufacturing, inspection, and testing processes to uphold superior quality standards.

Customized Configurations
Displayed below are a variety of standard condenser anodes, while customized shapes, weights, and configurations are readily available upon inquiry.
