Overview
CerAnode™ ASAI Air-Cooled Rectifiers are compact DC power supplies engineered for impressed-current cathodic protection (ICCP) systems. Designed to convert AC input power into adjustable DC output, ASAI rectifiers deliver stable current control for pipelines, storage tanks, marine structures, and other cathodic protection applications.
Built for long-term reliability and serviceability, the ASAI platform combines efficient silicon rectifier technology, heavy-duty transformer construction, and ventilated air-cooled enclosures engineered for continuous ICCP operation in outdoor and industrial service environments. Configurable output ranges, monitoring options, and enclosure styles allow the system to be tailored to a wide range of cathodic protection requirements.

Oil-Cooled Rectifier (OSOI/OSXI)
CerAnode™ OSOI and OSXI Oil-Cooled Rectifiers are high-capacity DC power supplies engineered for impressed current cathodic protection (ICCP) systems requiring continuous operation in demanding environments. Utilizing dielectric oil for transformer and rectifier cooling, these units provide stable DC output while minimizing thermal stress under high electrical loads.
Multi-Channel Rectifier (REC)
CerAnode™ REC Multi-Channel Rectifiers are advanced DC power supplies engineered to independently power multiple impressed current cathodic protection (ICCP) circuits from a single unit. Designed for complex corrosion protection systems, each output channel provides individually adjustable voltage or current to optimize protection across multiple structures or anode beds.
Fiberglass Junction Box (JBF)
CerAnode™ JBF Fiberglass Junction Boxes are non-metallic enclosures engineered to protect electrical connections in cathodic protection (CP) systems. Constructed from fiberglass-reinforced polyester (FRP), these junction boxes provide a durable, corrosion-resistant solution for housing anode leads, structure cables, reference electrodes, and monitoring circuits in demanding environments.
Explosion-Proof Junction Box (JBE)
CerAnode™ JBE Explosion-Proof Junction Boxes are heavy-duty electrical enclosures engineered for cathodic protection (CP) systems operating in hazardous locations. Designed to safely contain electrical connections in environments where flammable gases, vapors, or combustible dust may be present, the JBE Series provides secure termination points while helping maintain the safety and reliability of critical corrosion protection infrastructure.
Stainless Steel Junction Box (JBS)
CerAnode™ JBSS Stainless Steel Junction Boxes are rugged electrical enclosures engineered to protect critical wiring and electrical connections in cathodic protection (CP) systems. Manufactured from marine-grade 304 or 316/316L stainless steel, the JBSS Series provides exceptional corrosion resistance and long-term durability for demanding industrial, marine, and offshore applications
Solar Power System (SOL)
CerAnode™ SOL Solar Power Systems provide reliable, off-grid power for impressed current cathodic protection (ICCP) systems operating where commercial AC power is unavailable or impractical. By combining high-efficiency solar panels, battery storage, and intelligent power management, the SOL delivers dependable DC power to rectifiers, anode systems, remote monitoring equipment, and other critical cathodic protection infrastructure.
