Rectifier Thyristor Technology

Electrolytic, surface-related processes, air-cooled high-current devices, Plasma Processes.

Product Design:
Air-cooled (forced or convection) Thyristor-controlled rectifiers for high-current applications. The rectifiers are electronically controlled manually, via an interface (provided by the customer) or analog signals for constant voltage and current control. Thyristor Technology is also applicable for pole changing processes, such as degreasing or hardchrome.

Our Thyristor Technology is also available in synth. cooling, water-cooling and synth.-water-cooling.

Customer Benefits:
Especially intended for output currents ≥ 2000 A the air-cooled Thyristor Technology is preferably used. The compact and service-friendly design complies with high industrial requirements and guarantees excellent process reliability.
