Product Description

M14X1.5 High-purity Magnesium Alloy Magnesium Anode Rod for Solar Water Heater

Magnesium anode rods (also called sacrificial anode rods) are core protective components in storage-type water heating equipment such as electric water heaters and solar water heaters.

Working Principle:

They operate based on the principle of electrochemical corrosion.

I. Magnesium's metallic reactivity is far higher than that of the steel inner tank, causing it to preferentially oxidize and corrode in water.

II. Current flows from the magnesium rod to the inner tank, protecting it from corrosion.

III. Once the magnesium rod is completely consumed, the inner tank will begin to corrode, thus requiring periodic replacement.

Product Features:
1) Protection First: Actively sacrifices its own strength to prevent corrosion and perforation of the water tank liner, extending the water heater's lifespan.

2) Easy Installation: Threaded interface design allows direct screwing into the pre-drilled mounting holes on the water heater.

3) Low Cost: Compared to replacing the water tank, the cost of periodically replacing the magnesium rod is very low.

4) Environmentally Friendly and Safe: Magnesium ions are harmless to the human body and can soften water and reduce scale formation.

Application Scenarios:

- Storage-type electric water heaters: Standard equipment for household and commercial storage-type electric water heaters.

- Solar water heaters: Used to protect the inner tank of pressurized water heaters.

- Air source heat pump water heaters: Protect the inner tank liner from corrosion.

- Industrial water storage containers: Corrosion protection for boilers and hot water circulation systems.

Cleverly utilize the principles of 
chemical original batteries to 
better protect the water heater from corrosion!

Magnesium rod is commonly known as magnesium anode, also known as anode magnesium block, used to prevent corrosion of metal inner vessels and soften the water quality of magnesium rods. In the water vapor, the metal inner vessels are made of Taisteel or manganese steel, and the cathode principle is sacrificed by the electrochemical corrosion protection of metals. The magnesium rod is used as anode and the metal inner vessel is used as a cathode. In this way, the primary cell is formed by a conductive water medium between the cathode and the anode. The anode of the battery is consumed by corrosion, while the internal conductor of the cathode is protected.
