RRU Series of  Automatic CP Rectifier
(Oil-Cooled and Air-Cooled)

Digital technology ensures superb reliability and provides flexibility to meet the requirements of today’s different fields of industry in the most efficient and cost effective manner.

Embedding of intelligent control systems based on the digital and micro-processor technology enables the functions of Impressed Current Cathodic Protection systems to be monitored and controlled remotely across of the SCADA (Supervisory Control and Data Acquisition) systems. SDP Co. has the pleasure of producing these kinds of intelligent and smart rectifiers in case of both standard and custom design in the various capacities.

RRU Series of Automatic CP Rectifier

Features of the SCADA Based Rectifiers
