SFO Magnesium Rod

Magnesium rods are commonly known as magnesium anodes, also known as anode magnesium blocks, which are used to prevent corrosion and soften water quality in solar water tank liners.

In the water heater, the magnesium rod is mounted inside the metal liner.The magnesium anode and the metal liner form a small electric resistance through water, and the magnesium anode starts to output current, and flows to the exposed metal liner to produce a polarizing film protective layer to prevent the inner metal from being corroded to reach the protection water tank.

Because magnesium anode itself consumes when it outputs current, it is called the sacrificial anode method.

Magnesium rod generates electric field vibration during the output current, so that the scale becomes loose, not easy to scale, and easy to clean.

In general,magnesium rod is replaced once in 1-2 years.However, in hard water areas, the corrosion rate of magnesium rods is accelerated and can be replaced once every six months to one year.

Disposing a magnesium rod inside the solar water heater can effectively reduce the scale on the electric heating surface, prevent the electric heating from being damaged due to local accumulation of scale, overheating, resulting in leakage, resulting in safety hazards.
