Round Condenser Aluminum Anode

Economical, lightweight, high efficiency condenser anode.



An economical option for saline corrosion protection, the condenser aluminum anode boasts higher current efficiency than magnesium and zinc counterparts in low-resistivity aqueous environments. It features a galvanized steel pipe core for easy mounting on steel studs and is widely used in cathodic protection for various applications.

Quality Substrate Material
Crafted from low-iron, high-purity alloys, our condenser aluminum anode meets the GS EP COR 201 standard.

Low Driving Voltage
The condenser aluminum anode delivers consistent performance in seawater and chloride-rich electrolytes, maintaining an operating 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
The aluminum condenser anode’s lower density compared to zinc ensures it is lightweight and easier to handle during installation.
