Rod Anode (CAR)

CerAnode’s CAR Rod Anode is a high-performance, MMO mixed-metal-oxide titanium rod designed for impressed-current cathodic protection (ICCP). It delivers reliable current output and long service life for a wide variety of structures, from internal pipelines to marine and industrial systems. Built with a robust titanium substrate and durable precious-metal-oxide coating, the CAR Rod provides stable, predictable electrochemical performance.

Its modular design allows for flexible installation, making it ideal for retrofits, new builds, and continuous anode strings.

Key Features & Benefits

Materials & Coating

Titanium Substrate: Made from high-quality titanium for excellent structural integrity.
Mixed-Metal-Oxide (MMO) Coating: MMO Coating ensures low consumption, long life, and stable performance.

Performance & Efficiency

Predictable Current Output: Provides controlled, consistent current for accurate cathodic protection.
Low Overpotential: Efficient electrochemical behavior reduces energy loss.
Long Service Life: MMO coatings combined with titanium yield a long design life, often decades.

Durability & Environment

Chemical Stability: Resistant to aggressive environments.
Mechanical Strength: Solid rod form resists bending, vibration, and mechanical stress.
Dimensional Stability: Titanium substrate maintains its shape over time; minimal loss of material.

Installation Flexibility & Maintenance

Available in various diameters and lengths to suit diverse system needs.
Can be connected in series (strings) for higher total output.
Low-resistance terminations for reliable electrical contact.

Applications

Internal pipe and valve protection in process plants.
Cooling water systems, including heat exchangers and water boxes.
Water intake structures in marine or freshwater environments.
Industrial vessels, tanks, and process equipment.
Deep or shallow ICCP anode beds (as part of an anode string)

Installation & Accessories

Prepare: Clean the substrate surface where the rod will mount; remove corrosion, scale, or debris.
Supports: Mount the rod via structural supports—clamps, brackets, or weld-plates as per design specifications.
Connection: Connect the anode cable to the rod’s terminal, ensuring a low-resistance joint and proper strain relief.
Multi-Rod Systems: Configure in series or parallel strings depending on design current and voltage.
Power Supply: Route the cabling back to the rectifier or power supply; label each lead for monitoring.
Monitoring & Commission the System: Verify that current output, voltage, and protection potentials meet design criteria.
Accessories: Include accessories like junction boxes, reference electrodes, and test leads to support ongoing monitoring.
Inspection & Maintenance: Inspect periodically to confirm continued electrical connectivity and check for signs of degradation.
