MediPlas Reactor

High-performance ozone generator as a component for industrial and medical applications

The MediPlasTM Reactor is a high-performance ozone generator. Depending on the selected process parameters and the type of gas supplied, the following reactive species are formed in the reactor: Ozone, hydrogen peroxide as well as nitrogen oxides. The exact composition of the sterilization medium can be varied according to customer-specific requirements.

It is based on cold atmospheric plasma (KAP) and can be integrated into applications as a component for cleaning, sterilization and disinfection. The MediPlas Reactor from TDK reduces the concentration of pathogens on contaminated surfaces. Odors and germs can also be eliminated by the ozone generator.

We are looking for partners who would like to benefit from the advantages of our DBD components and integrate our modules into their systems.

The MediPlas ozone generator can be used in a wide variety of applications. In the video you can see the following experiments:

  • Oxidative decolorization of organic dyes
  • Ozone treatment of food against microorganisms
  • Oxidative bleaching of textiles
  • Cleaning of the inside of a hose

Use in Cleaning in Place

The cold atmospheric plasma components can be used wherever hygiene is an important consideration. This can be optimized by incorporating ozone into Cleaning in Place (CIP). Instead of the typical six steps, only four steps are required due to the incorporation of ozone.

Cleaning in place is a method for cleaning continuous processes without dismantling the system. The method was originally developed for the food, beverage and pharmaceutical industries. But the principle can also be used in medical technology.
Sterilisation in Place (SIP) is mainly used in pharmaceutical and biological production facilities and serves not only to clean but also to sterilise the system. Usually, sterilisation takes place through superheated steam or with special chemicals. The cleaning or sterilisation cycle can be optimised on site by integrating ozone into the process.

Customised output gases of the gas flow reactor

The MediPlas system does not require additional chemicals or high temperatures, but uses only air (or oxygen) and electricity to produce efficient sterilizing gases.

Input gas → Output gas:

  • Oxygen (O2)→ very high ozone concentration (O3)
  • Dry air (O2 + N2) → Ozone; temperature-controlled Nitrogen oxides (NOx)
  • Humid air (O2 + N2 + H2O) → Ozone; temperature-controlled Peroxides and acid


  • High durability; easy integration
  • High ozone concentration
  • Stable against humidity
  • Operates with pure (medical) oxygen to provide high ozone concentrations > 50,000 ppm. High oxygen concentrations can also be provided with pressure swing absorption (PSA).
  • High NOx operation for inline fertilization for plants.
