Overview
The CerAnode™ Expandable Rod Anode (EAR) is a high-performance EMMO™ (Enhanced Mixed-Metal Oxide) anode engineered for impressed current cathodic protection (ICCP) systems requiring flexible deployment and optimized current distribution. Designed for deep, shallow, and irregular anode bed geometries, it delivers consistent current output and long-term durability.
Constructed on a titanium substrate with a ceramic EMMO™ coating, the EAR provides a stable, corrosion-resistant surface for extended service life in aggressive environments. Its expandable, tension-adjustable design enables controlled deployment and uniform current distribution across long runs and variable installation conditions.
Factory-assembled and installation-ready, the CerAnode™ EAR minimizes field handling while ensuring low-resistance electrical connections and reliable system performance in critical infrastructure applications.
