Corona generator

In a corona system, the corona generator and high voltage transformer generate the high voltage that is applied to the corona electrodes. In addition to this, the generator controls the overall corona system.
With our 9000 series of corona generators, SOFTAL has already raised the bar in the corona generator market in all power segments.

Characteristics

Economic operation SOFTAL generators are setting the industry benchmark for efficiency and cost effectiveness. Careful balancing between generator, transformer and treatment station ensures that the system operates at resonance frequency. This means that the treatment system operates at maximum efficiency, keeping the operating costs as low as possible over the entire lifetime.
Innovative operation The operating concept of SOFTAL generators combines the strengths of two previous concepts. Where generators were previously only operated with a rotary switch or touchscreen display, the new series of generators combines the advantages of both designs. Touchscreen operation is used mainly for menu navigation while the rotary switch can be used to change settings and values quickly and precisely.
System control The generator display is also the main user interface with the overall system. A corona station is equipped with numerous sensors and actuators which supply the generator with the necessary control signals.

In most applications the generator display is also the main user interface with the overall system. A corona station is equipped with numerous sensors and actuators which supply the generator with the necessary control signals. Status and notification messages concerning corona station operation appear on the generator display. The Generator also implements customer-specific and special functions such as speed-dependent control of corona power (CCP), skip treatment (SCT) and pulse mode (DCR).
Plant control interface In addition to the generation of high voltage and the control of the corona station, the generator also acts as the interface with the production environment. Standard interfaces such as Profi-Bus and CAN and customer-specific potential-free inputs and outputs ensure that generator and station can be integrated into any surrounding and any process.
Transparency and usability To optimize processes and to make user interactions more transparent, SOFTAL generator can be equipped with a diagnostic and operating memory, which keeps a log of the last 100 messages and user commands. This provides valuable information for the analysis and optimization of processes.
Reliability Numerous setting options and background functions ensure a safe, reliable and economical operation of a SOFTAL generator under all operating conditions. Every single one represents decades of experience in the design, construction and maintenance of corona and plasma generators. Uninterrupted operation depends on all those small background adjustments that the high-tech electronics perform while the generator is 'simply doing its job'.
