Dehne's Plasma Tube

Our patented Plasma Tube is made of a combination of various types of new materials that provides smooth and consistent discharge of plasma.

Our Plasma Tube emits a purple light, the process in which a corona of plasma is created around the tube, hence, “Cold Plasma” – plasma that is safe to the touch.

Our Patented Plasma Tube discharges 450,000 Negatives Ions per second.

In negative ion production, it must be noted that the lifespan of small ions is only a few seconds. They would have completely disappeared after the shortest time if they were not constantly further produced. However, small ions are very mobile and are deposited on air constituents. They then form large ions which have a considerably longer lifespan.

Our product does not produce toxic by-products such as ozone or Nitrogen oxides.

With the process, Dehne’s Plasma Tube is patented and Institutes in Europe had recognize that it is able to inactivate bacteria, viruses, fungi, spores, and mites. All kinds of bacteria include those resistant to antibacterial or antiseptic.

Besides that, it is also able to remove the unpleasant odor, VOC (Volatile Organic Compound) ie: Formaldyhide, and neutralize Carbon monoxide and Nitrogen oxide from the air.

Exposure to VOC vapors can cause a variety of health effects, including eye, nose, and throat irritation, headaches, nausea, and damage to the life, kidneys, or central nervous system. Higher concentrations of the gas can lead to
unconsciousness, coma, and even death.

The ideal way to control and neutralize the toxic gases emitted by those sources is to have Dehne’s Cold Plasma Air Steriliser.

Dehne’s Cold Plasma is your choice to consider.

The hydroxyl radical (OH-radical, HO) is a molecule consisting of one hydrogen and one oxygen atom. As a radical it has a single unpair electron, it is very reactive. It combines with the (11) oxygen atom in nanoseconds.
The video below shows how the cold plasma works
How is hydroxyl radical formed in the atmosphere?
  • In nature, Hydroxyl Radical (OH) is formed in the atmosphere when ultraviolet light (UV) from the sun strikes in the presence of water vapor (H₂O).
  • Then the oxygen atom (O) reacts with water vapor to produce two OH radicals.
  • OH is the most important oxidant in the atmosphere (Outdoor and indoor).
  • During the night- time or in those places without sunlight, hydroxyl radical (OH) concentrations are close to zero since sunlight is needed for its formation.
  • In such a condition, Dehne’s Cold Plasma Discharge becomes important. The Cold Plasma Discharging replicates nature’s process to continue to produce hydroxyl radicals.
  • The Cold Plasma Discharge will split the oxygen molecule into an oxygen atom and a hydrogen molecule to the hydrogen atom. The oxygen atom and hydrogen atom will bond together to form hydroxyl radicals.
  • The High reactivity of OH is associated with a very short lifetime (in Nano Second).
  • Hydroxyl radicals are natural oxidizing agents. It can kill bacteria and Viruses, Eliminate unpleasant odors, remove fine dust particles in the air, and Neutralise toxic gases.
  • Hydroxyl radicals are non–toxic to humans, animals, and plants. Yet they kill bacteria, viruses, and mold.

Introduction of Dehne’s Cold Plasma Technology
Non Thermal Plasma Technology is a technology, which uses a soft corona discharge method to generate negative ions to sterilize or to clean the air naturally. (air sterilizer) A negative ion is defined as an airborne ion having a negative charge. It can easily be found in the air near waterfalls, mountains and forests.

Non Thermal Plasma technology is created from the discharging tube with purple corona glowing and its resultant interaction with oxygen molecules in its immediate vicinity within the perimetric wire gauze.

Frequently Asked Question

In terms of height above the floor, where is the ideal placement for Dehne's Cube CV1?

For optimal installation, it is recommended to position Dehne’s Cube CV1 at a height of approximately 1 to 2.5 meters from the floor. While the placement within the room is of secondary importance, we suggest placing the device in the middle for best results.

How far are hydroxyl radicals emitted in a room via the Cube CV1, and how long does it take for the protective hydroxyl radicals to be evenly distributed throughout the room?

The flow and diffusion of hydroxyl radicals can be achieved after approximately 15 minutes per Cube CV1 in a room with a maximum volume of 120 m³. However, it is recommended to activate the Cube Cv1 one hour before multiple people enter the room.

How long do the hydroxyl radicals emitted by the Cube CV1 remain active?

Hydroxyl radicals remain active for up to one hour.

How do hydroxyl radicals oxidize bacteria, fungi, and viruses?

Hydroxyl radicals oxidize the primary unsaturated fatty acids in the fats of the cell membrane of single-cell organisms, such as bacteria, fungi, and viruses. This destroys the cell membrane and denatures the virus.

Are the hydroxyl radicals emitted by the Cube CV1 dangerous to humans or other living organisms?

The cell membrane in eukaryotic cells, including plants, animals, and humans, has a different structure, meaning hydroxyl radicals have practically no negative effect on these cells, and humans are not at risk from exposure to hydroxyl radicals.

Does the Cube CV1 emit hazardous byproducts such as ozone or nitrogen oxides?

The values measured with the Cube CV1 show no change in the premises’ values during or after operation compared to measurements taken before use.

Does the Cube CV1 comply with the standard EN 14476 (Chemical disinfectants and antiseptics: Quantitative suspension test for evaluating virucidal activity in the medical area, Test method and requirements (phase 2, step 1))?

Yes, the Cube CV1 complies with standard EN 14476, whereby the basis of the effect is not a chemical process but rather an electrophysical one.

Is the Cube CV1 effective against mutations of the SARS-CoV-2 virus, which causes COVID-19?

Yes, hydroxyl radicals neutralise viruses regardless of mutation.

Why was the test bacterium Enterococcus faecium used in the expert statement?

The test bacterium Enterococcus faecium is recommended by the DGHM (German Society for Hygiene and Microbiology) and has been used for decades in disinfection analysis. It is much more resistant than a large number of known bacteria and viruses and also has a low level of human pathogenicity. Therefore, the test bacterium is regarded as representative of all enveloped viruses and bacteria in the RKI A+B* categories (Robert Koch Institute, Germany).

Why is more humid air better for the disinfection of germs by the Cube CV1?

Reactions are limited in absolutely dry air because water vapour content is necessary for the formation of hydroxyl radicals.

How does the Cube CV1 affect allergy sufferers, such as those with house dust allergies?

The Cube CV1 works not only against enveloped viruses but also against pollen and mold, making it a helpful tool for allergy sufferers to improve their quality of life.

Can the Cube CV1 eliminate unpleasant odours?

Yes, the Cube CV1 is able to eliminate unpleasant odours in a short period of time.

Can Dehne's Cold Plasma (Cube CV1) remove volatile organic compounds (VOCs)?

Yes, the Cube CV1 is able to remove VOCs, especially formaldehyde, by neutralizing the gases.

What is the service life of the plasma tube in the Cube CV1?

The Plasma tube does not have a lifespan.

Will the performance of the plasma tube in the Cube CV1 decrease over time?

To retain performance, cleaning the Plasma Tube once every four months is advised.
