SCANIA ANODE

Function and technical context

The TEN02201 sacrificial anode acts as a cathodic protection element in Scania marine engines, interposing a low-nobility metal between the metal structure of the engine and the electrolytic medium of water to absorb galvanic corrosion. It works directly in the seawater cooling system and in areas submerged or in contact with the cooling fluid, where the electrical potential differentials between different metals accelerate the deterioration of critical components such as jackets, heat exchangers and exhaust manifolds. Without an anode in correct condition, galvanic corrosion silently and progressively attacks high-cost parts, compromising the tightness of the cooling circuit and the structural integrity of the block. The reference TEN02201 is designed specifically for Scania engines, guaranteeing the correct geometry, alloy and electrical contact for effective protection.

When to replace this part?

Sacrificial anodes must be inspected at the beginning and end of each nautical season, and replaced when they have lost approximately 50% of their mass, since below that threshold the cathodic protection is no longer effective. An unequivocal symptom of a depleted anode is the appearance of pitting or reddish corrosion on metal surfaces of the engine that are normally smooth, as well as unusual lime deposits in the seawater circuit. Preventive replacement of the TEN02201 anode at each annual maintenance is the most economical measure to avoid serious breakdowns in the cooling system during navigation.
