Oil/water-cooled systems are a strong and reliable solution for applications in harsh industrial environments. These designs allow a more compact integration of power. The main components are built into a corrugated steel tank. The heat losses are transferred through a heat exchanger allowing an external cooling water circuit to remove the heat. The adjustment of these rectifiers is done by means of a motor driven variable transformer.
