Overview
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.
Designed for offshore, coastal, industrial, and utility applications, OSOI and OSXI rectifiers feature sealed oil-filled construction that protects internal components from moisture, dust, salt spray, and corrosive atmospheres. Their rugged design delivers long service life, dependable performance, and low maintenance for critical cathodic protection infrastructure.
Key Features & Benefits
Oil-Immersed Cooling
Dielectric oil provides efficient heat transfer, allowing continuous-duty operation while reducing internal operating temperatures and extending component life.
Heavy-Duty Transformer Design
Oversized transformer construction maintains stable DC output under varying load conditions and provides reserve capacity for future system expansion.
Adjustable DC Output
Multi-tap or controlled output configurations allow precise voltage and current adjustment to meet specific cathodic protection requirements.

Engineered for your application
No two cathodic protection systems are identical. Tell us the current requirement, electrolyte and installation constraints and we will configure the anode around them.
Air-Cooled Rectifier (ASAI)
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.
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.
