Key Features of Zinc Pencil Anodes

• Engine heat exchangers have a common problem of corrosion due to the difference in metal between casing and tube stack.
• Employing zinc pencil anodes reduces the corrosion on the casing prolonging the life of both casing and tube stack whilst in sea water.
• Zinc is the only material that has an official specification
• Zinc is a well-proven anode material and its capacity is virtually unaffected by the operating current density, although the driving voltage diminishes with increasing temperature therefore it has limited application.
