Clean air through tiny lightning flashes, that is the core of the Corona. Contaminants in the air that never before were able to be removed effectively can now be treated. HMVT, together with Oranjewoud and the Technical University of Eindhoven developed a Pulsed Power Cold Plasma Reactor that can treat various contaminants with very high flow rates. 

The Corona reactor generates electrical pulses with a peak power up to 100 MW. These pulses are lead through a high voltage cable to the electrodes of the reactor. The electrical pulses on the electrodes form a cloud of tiny lightning flashes also known as  Corona discharge or cold plasma. This cloud of sparks contains both ions and electrons. Especially the electrons are important for this application. Due to the pulse these electrons 
acquire sufficient energy to initiate a chemical reaction. Chemistry with electrons, without thermal heating of the gas. Because the gas can remain cool, the Corona Technology costs much less energy than conventional treatment methods.  

In the Pulsed Power Laboratory in Eindhoven, the Netherlands the Corona team completed the construction of a corona reactor-pulsed power combination. It is an approximately 1 m3 reactor with 7kW corona power. Sufficient to treat large volumes of contaminated air streams. In the future through  ongoing developments we will be able to treat flows up to 300.000 m3/hour.

The uniqueness of the Corona reactor is its ability to treat a large  variety  of  substances.  Next  to  its  ability  to  remove odors from the air, we have also achieved good results with 
treating:  Volatile Organic Compounds, NOx, Fine dust particulates, H2S, Ammonia 
Moreover, the corona plasma also inactivates micro-organisms. In short, one system to solve various air polution substances.
