The driver for the high-performance ozone generator “MediPlas®-Reactor” as a component for sterilization and disinfection in clean in place (CIP)

In combination with the MediPlas® Reactor based on cold athospheric plasma (CAP), the driver for ozone generators can be used as a component in the medical field for disinfection and sterilization of surfaces. Pathogens are thus effectively eliminated and there is no need to use chemicals or vacuum. This results in cost savings and its use is also environmentally friendly.

       

Application areas of the driver for ozone generators

The high-voltage source is intended for operation with a suitable plasma generator. The driver for ozone generators converts a DC low voltage to an AC high voltage using an auto-resonant circuit topology. The output frequency automatically adapts to the load being operated. The MediPlas® Drive can drive customer specific DBD-assemblies with up to 300 pF capacity and atmospheric air gap up to 2 mm distance to ground electrode. Each MediPlas® Drive is able to feed three MediPlas® Reactor blocks.

The MediPlas® Reactor generates ozone. RONS (reactive oxygen and nitrogen species) and ROS (reactive oxygen species) arise in the secondary plasma. Medical products can be reprocessed and germs and odors can be eliminated. The plasma components can be used, for example, in applications in medical technology, in industry, in packaging, in consumer goods and in agriculture for disinfection and sterilization.

The typical clean in place cycle contains six steps:

1. rinse
2. wash
3. rinse
4. chemical/thermal disinfection
5. rinse and
6. drying.

The typical clean in place cycle (CIP) can be optimized by integrating ozone generation. The optimized clean in place cycle with the integration of ozon gerneration contains only four steps:

1. rinse
2. wash
3. rinse and
4. disinfect.

This leads to savings in in the sinner’s circle in time, energy and consumables.
