Lida® Rod Anodes

Lida® Rod Anodes

Providing High Current Outputs With a Low Coating Wear Rate

LIDA® Rod Anodes are comprised of a titanium substrate with a mixed metal oxide coating. The mixed metal oxide is a crystalline, electrically-conductive coating that activates the titanium and enables it to function as an anode.

Rod Anode Applications

  • Process Vessels
  • Water Condensor Boxes
  • Heat Exchangers
  • Water Intake Structures


  • Lower Cost Per Ampere Year
  • Constant Electrical Resistance
  • No Hassles


  • High Current Output
  • Low Coating Wear Rate
  • Five Year Product Warranty
  • Also available as Rod Anode Assemblies

Anode coating may be selected to match freshwater, brackish water, seawater, coke, or sand environments. De Nora LIDA® Rod anodes are available in the following standard sizes: 

–  1/8″ x 4′      

–  1/4″ x 4′    

–  1/2″ x 4′     

–  3/4″ x 4′

Anode Life Projections

Due to the extremely low consumption rates and dimensional stability of mixed metal oxide anodes, the electrical resistance of LIDA® Rod Anodes remain essentially constant with time. The high current density capacity of De Nora mixed metal oxide anodes has the added advantage of allowing high current overloads for initial polarization without causing harm to the anode.

Operating Environment

Selection of the anode coating is based on operating environment:
FW Freshwater or Brackish Water
SWT Seawater
