ADOR ESP Transformer Rectifier ADOR ESP Transformer Rectifier

12x is full set. Each 2500Eur/piece

High-voltage Transformer–Rectifier (TR) set manufactured by ADOR Powertron / ADOR-CORONA, designed for supplying Electrostatic Precipitator (ESP) sections with stable high-voltage DC power.
This unit converts 400 V / 50 Hz AC into 80–95 kV DC at approx. 1.4 A output.
Built with an ONAN-type oil-cooled transformer, integrated rectifier assembly, HV bushings, protective circuits and monitoring components.
Equipment from a working installation in Elektrėnai (LT). Fully maintained and suitable as a direct replacement or spare for large ESP systems.
