Casting Magnesium Anode Rod
Casting magnesium rod is often selected by Germany, Spain and other European countries and India, Vietnam and other southern Asian countries, generally suitable for smaller water heaters, the installation of magnesium rod is generally installed on the heating tray, more than 50mm from the heating wire, the installation should be vertical and insulated. The selection of magnesium rod specifications is determined according to the protection area, volume, tank diameter and height. For a 30L electric water heater, the outer diameter of the magnesium rod is usually 16-20mm and the length is approximately 200mm. The magnesium rod used in a 60L electric water heater is generally about 300mm long and about 1 inch in diameter.
