News from MATCOR December 2025
This month, we’re focusing on cathodic protection rectifiers—the power source behind every effective impressed current cathodic protection (ICCP) system. From maintaining the right current output to selecting the best design for your environment, rectifiers play a critical role in protecting pipelines, tanks, and other buried infrastructure.

The Importance of Cathodic Protection Rectifiers
Cathodic protection rectifiers are the heart of any impressed current cathodic protection (ICCP) system. By converting AC power to stable, regulated DC output, rectifiers deliver the protective current that prevents corrosion on critical infrastructure.
MATCOR offers CP rectifiers in every standard configuration — with options available for nearly any voltage, current output, or installation requirement.

How to Build the Best CP Rectifier
Modern rectifiers are reliable and built for long service life — but not all units are engineered to the same standard. Design decisions in components, cooling, enclosures, and monitoring capability can significantly impact long-term performance.
In this JA Electronics article, learn the six key features to look for when specifying a high-quality CP rectifier.
When to Use Oil-Cooled vs. Air-Cooled Transformer Rectifiers
Oil-cooled and air-cooled rectifiers each provide advantages depending on environment, power requirements, and operating conditions. Oil-cooled units excel in high-power or harsh environments, while air-cooled designs remain the most common for standard outdoor installations.
This MATCOR article breaks down when each type is the right fit for your CP application.
