Excellence of AI-Anode

1. Al-Anode are economical due to their higher effective electrical capacity per unit weight compared to Magnesium alloy anodes and zinc alloy anodes.
2. Polarization action is minimal even over an extended period, maintaining a high anode potential through the service life, resulting in stable output current and high current efficiency.
3. Anode weight is lighter for the same effective output, it is more convenient for transportation, handling, and installation.
4. There are no harmful components in the anode composition, eliminating concerns about environmental pollution.
5. The moderate potential difference allows for excellent automatic regulation, preventing overprotection.
6. Anode consumption is uniform.
7. It is still effective even in relatively contaminated seawater.
8. With low potential difference against iron, hydrogen generation is minimal, avoiding damage from hydrogen evolution.

ZN-ANODE Excellence

1. Over an extended period, polarization action is minimal, maintaining a high anode potential through the service life, resulting in stable output current and high current efficiency.
2. With self-adjusting capabilities, the generated current is regulated based on the degree of polarization, avoiding unnecessary consumption.
3. ZN-ANODE, as a metal that does not produce sparks even when in contact with iron from a height, is the most suitable anode material for hazardous material handling facilities.
4. With a low potential difference against iron, hydrogen generation is minimal, avoiding damage from hydrogen evolution.
5. Aluminum or magnesium alloy anodes can generate a significant amount of electrolytic byproducts, requiring periodic cleaning. However, ZN-ANODE does not require cleaning.
6. The byproducts generated as ZN-ANODE leaks stray current and undergoes polarization in seawater attach to the surrounding iron surfaces, serving as corrosion inhibitors.
