Process Anode (RPA)

The CerAnode RPA Process Anode is a compact, factory-assembled titanium anode engineered for demanding process environments. Its high-strength titanium substrate is coated with a rugged conductive ceramic layer, forming one of the most durable MMO mixed-metal-oxide anodes on the market.

Designed for impressed current cathodic protection systems, this unit delivers long-life corrosion protection with minimal maintenance. It’s a top choice for tank cathodic protection, marine structure protection, and industrial corrosion control solutions where reliability matters.

With its sealed, low-resistance factory assembly, the RPA simplifies installation while providing performance typically reserved for large pipeline anode systems or deep well anode systems.

Key Features & Benefits

Durable Construction

Titanium substrate with ceramic MMO coating ensures high wear-and-corrosion-resistance in harsh environments.
An arc-plasma-sprayed dielectric interface secures insulation and mechanical stability for long service life.

Installation-Friendly & Quality Assured

Factory-assembled unit means fewer field connections, reducing risk and installation time.
Compatible with standard junction-heads or conduit boxes, offering flexibility in retrofits or new builds.

Long-Life Performance

Efficient MMO anodes consistent current output over years of service.
Ideal for low-maintenance corrosion protection where downtime must be minimized.

Typical Applications

Heat exchangers, water boxes, and industrial process vessels
Pumps, valves, and piping in chemical plants or offshore platforms
Marine cathodic protection anodes for offshore and on-shore structures
Pipeline anode systems and impressed current systems for infrastructure in harsh soils

Installation & Accessories

Mount Anode: Mount the RPA into a compatible process fitting or junction head, ensuring that the dielectric interface is properly sealed and isolated from surrounding steel.
Accessories: Standard accessories include junction heads or rigid conduit boxes. Custom housings are available for non-standard applications.
Specifications: Use appropriately insulated cable and secure terminations suitable for the environment, especially in chloride-rich or chemically aggressive settings.
Inspections & Maintenance: Ongoing maintenance is minimal thanks to the factory build, though periodic checks of connection integrity and current output are recommended.
