TR For Cathodic Protection

Metallic structures are at risk of corrosion when submerged in water or buried underground for extended periods of time. Cathodic protection transformer rectifier units (also known as TR or TRU) are used for Impressed Current Cathodic Protection (ICCP) systems. These units are purpose-built and generally feature remote control monitoring capabilities and current interrupters. The output of the transformer rectifier in the impressed current cathodic protection system should be optimized to provide sufficient current to protect your assets.

At BSS Technologies we offer a range of TR unit including ATEX to help you protect your critical assets and infrastructure from corrosion. Impressed current cathodic protection is a proven system for effectively controlling corrosion on metallic structures.
