The magnesium galvanic anode is an essential component for the protective mechanism of heating systems. It is made from high-quality materials and measures 25x390mm, making it easy to install in various applications. This anode is proven to work against electrolysis, which can be caused by the presence of water, thereby extending the lifespan of the system's metal components. By using Galmet's magnesium anode, you ensure that your heating system remains protected from the harmful effects of corrosion.
