Cathodic protection using impressed current electronic anode (standard)
As an alternative to galvanic systems (combination of materials with different electrical potential) another protection method is available, consisting in
imparting to the metal structure to be protected a direct current equal and opposite, obtaining this way the neutralization of voltages formed inside the
tank.
Thanks to modern techniques, an innovative cathodic protection electronic system is available, by impressing direct current.
Main advantages are:
active protection by impressing direct current from an external source
excellent operational flexibility, for respond to different types of internal lining and to variable mass of water
maintenance costs reduction due to the permanent protection of the system
