Canister Anodes (CAC-CPW)

CerAnode’s CAC‑CPW Canister Anode is a factory-preassembled impressed-current anode pre-packed in a rugged steel canister with highly conductive backfill.

The core is an MMO mixed‑metal-oxide or iridium‑tantalum coated titanium element, delivering reliable long‑term current output.

Because it’s pre-packed, the canister simplifies installation, especially in environments where placing loose coke backfill is difficult or costly.

Key Features & Benefits

Materials & Construction:

High‑Stability MMO Coating: The titanium anode core is coated with a durable mixed-metal-oxide, such as iridium‑tantalum, to provide long life and stable electrochemical behavior.
Robust Canister Housing: Galvanized steel canister protects the anode core during handling and provides a stable mounting for installation.
Conductive Backfill: Pre‑packed with Loresco® Coke breeze for low-resistance conduction and efficient current transfer to the surrounding environment.

Electrical & Performance

Low Connection Resistance: The factory cable to anode termination ensures very low resistance (< 100 µΩ) for efficient current flow.
Consistent Current Output: Designed for predictable, stable current delivery throughout the design life, supporting reliable ICCP protection.
Optimized Ground‑Bed Efficiency: Coke backfill in the canister improves ground‑bed contact, reducing power losses and rectifier load.

Durability & Environment:

Long Design Life: MMO‑coated titanium core resists consumption, enabling multi‑decade service when sized correctly.
Corrosion‑Resistant Housing: Steel canister and backfill materials maintain structural integrity to support long-term buried or immersed use.
Flexible Environment Compatibility: Suitable for a variety of soil types, including wet or marshy soils, shallow or horizontal ground beds.

Installation & Maintenance

Pre‑packaged & Ready to Use: Delivered with backfill already packed, reducing field labor and risk associated with manual backfill placement.
Custom Specification Options: Canister size (diameter, length), cable length and gauge, insulation type, and connection style (e.g., XLPE, fluoropolymer) can be tailored.
Monitoring‑Friendly: Termination designed to integrate with test leads, junction boxes, reference electrodes, making commissioning and inspection straightforward.

Applications

Impressed‑current cathodic protection of buried or aboveground storage tanks.
Pipeline ground beds, especially in shallow or horizontal installations where space is constrained.
Marshy or wet soils where field backfill might be unstable or impractical.
Remote or hard-to-access CP systems where pre‑packaged anodes minimize installation complexity and risk

Installation & Accessories

Site Preparation: Excavate or bore to the design layout, ensuring space for the canister and planned backfill or embedment.
Place Canister: Lower the pre‑packed canister into the bed, making sure it is properly seated and oriented.
Terminate Cable: Connect the factory‑supplied lead cable to your header or rectifier source using the low‑resistance connection.
Backfill / Embed: Surround the canister with soil or other specified media per design; no need for manual coke packing since it’s pre-packed.
Commission & Monitor: Install test leads, reference electrodes, and junction boxes; energize system and verify current, voltage, and polarization criteria.
Inspect Periodically: Confirm electrical continuity, verify performance, and check for signs of corrosion, cable damage, or canister degradation.
