Air-Cooled Thyristor Technology

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

Product Design
A highly robust adjustment type, either air self-cooled or air external cooled (for high current applications) installed, compact and universally applicable. Depending on the process, it can be controlled by constant current or voltage, manually or via a customer-specific interface. Due to the electronic adjustment, certain pulse applications are also possible. Thyristor technology is also used for polarity reversal processes such as degreasing or hard chrome.

Our thyristor technology is also available as synth. cooled, water-cooled and synth.-/water-cooled variants
