Magnesium anode chain 1" 1590 - VF300/400/500, KOMPAKT300 83.30.27

Electrochemical protection of water heaters

The chain magnesium anode is a key element of the corrosion protection system in domestic water heaters. It works in conjunction with the enamel layer, creating a comprehensive barrier that protects metal components from the harmful effects of the electrolyte, which is water.

Wear and factors affecting durability

The rate of magnesium anode wear is not precisely defined and depends on many environmental variables. Domestic water hardness is the main factor determining the corrosion rate - the higher the mineral content, the more intense the electrochemical processes.

The variety of installation materials with different electrochemical potentials (steel, copper, brass) generates natural corrosion micro-cells in the aqueous environment. The magnesium anode functions as a sacrificial element, which through its electrochemical activity protects the remaining metal components from degradation.

Inspection and replacement procedures

Regular inspection of the anode condition should take place at least once a year, allowing for an assessment of the degree of wear relative to the original volume. Replacement becomes necessary upon exceeding 2/3 of the initial volume or at most every two years, regardless of the visual state of the element.

A proactive approach to magnesium anode replacement has a direct impact on maintaining the manufacturer's warranty conditions. Neglecting this procedure may result in the loss of warranty protection and accelerated degradation of the heating device's internal metal components.

Application and compatibility

The chain model with a diameter of 1 inch has been specifically designed for the VF300/400/500 and KOMPAKT300 water heater series, ensuring optimal contact surface area between the electrolyte and the active material. The design allows for easy installation and trouble-free replacement without the need to dismantle the entire device.

The versatility of the solution allows for use in both new installations and modernizations of existing heating systems, maintaining full compatibility with various types of enameled water heaters available on the market.
