High Current Output
This extruded anode rod has high surface and length ratios in relation to cross-sectional area, this allows a greater current per weight than typical cast anodes. By supplying stronger current, our magnesium pencil anode rod can deliver effective protection to water heaters, even in higher resistivity electrolytes
Uniform Current Distribution
With a thin steel core running the entire length of the anode as a support, this aluminum anode rod provides a uniform and efficient current distribution to ensure stable performance.
Easy Replacement
The anode rod is easily replaceable and should be checked each time the water heater tank is drained. Generally, anode rods should be replaced when the corrosion has consumed approximately 75% of the rod’s mass. Our anode rod is expected to provide up to two years of corrosion protection.
Strict Quality Control
By conforming to ISO 9001:2015 standards, our aluminum anode rods are manufactured, inspected, and tested in accordance with our stringent quality control procedures to ensure peak performance.
Customized Configurations
We can easily configure various anode shapes and sizes to cater to all desired specifications.
