Core offering

Cathodic Protection Co. Ltd. manufactures and supplies cathodic protection equipment (transformer rectifiers under the TRUst™ brand, mixed metal oxide anodes including ELGARD™, junction boxes, cables, test stations and accessories) and provides specialist engineering services for the design, installation, inspection, and commissioning of CP systems on buried or submerged metal structures such as oil & gas pipelines, storage tanks, marine jetties, offshore platforms, and reinforced concrete. The company also produces the proprietary Cuprion® electrolytic marine anti-fouling system for seawater pumping systems, available in pump-mounted, deck-mounted, ship-based, and industrial configurations.

Product overview

Cathodic Protection Co. Ltd. (CPCL) operates as a specialized engineering and manufacturing firm rather than a software-as-a-service company. Its product portfolio is organized around three core pillars: (1) Transformer Rectifier Systems — the TRUst™ branded range of transformer rectifiers (including thyristor, variac, tapped, and SMPS variants), the TRUst™ Remote Monitoring & Control System (RMCS), and ATEX hazardous area certified units; (2) The Cuprion® Marine Anti-Fouling System — available in pump mounted, deck mounted, ship based, and industrial configurations, using impressed current on copper/aluminium anodes for biofouling prevention; and (3) CP Systems Design, Engineering & Materials — covering full engineering services from survey to commissioning, plus a full suite of manufactured and sourced CP materials including anodes, junction boxes, test stations, cables, and ELGARD™ MMO anodes. The company also provides field engineering services for installation, inspection, and pipeline surveys globally.
