Magnesium Alloy Sacrificial Anode for Electric Heater Protection of
Customized Size
1. Description:
The magnesium anode is an important part in the electric water
heaters. It protects the water tank from corrosion. So the quality
of anode is of the most importance to the life of water heaters.
our company have different type of anode and can produce product
according customer’s demands.

3. 3. Applications:
1. Impressed current cathode protection system
We have successfully developed a new kind of impressed current
cathode protection system for water heaters. The protection system
will adjust the current density automatically in pace of working
temperature of the water heater. It will provide the best
protection condition to the water tank, and extend the life of
anodes.
2. The indication apparatus
The life length of magnesium anode will be different because of the
different working environment and size. the indication apparatus
will show the real time condition of the magnesium anode.
3. The anode dissipation alert apparatus
The apparatus can give the detail data about the magnesium anodes.
It will alert when the anode dissipation reaches to a target point.
4. High efficiency magnesium rod anode
Seal the connection point to control the corrosion between
magnesium anode and the connection point in order to extend the
life of anode.
5. Our company cooperates with some famous universities and
research institutes to develop new anticorrosive products.
4. Competitive Advantage:
We have successfully developed a new kind of impressed current
cathode protection system for water heaters. The protection system
will adjust the current density automatically in pace of working
temperature of the water heater. It will provide the best
protection condition to the water tank, and extend the life of
anodes.
