The UV – Air Desinfection Tower is an air purification system that efficiently removes viruses and bacteria using the proven UV-C technology. The products are safe for the end user because no UV-C radiation is emitted. The ambient air is supplied and discharged to and from a shielded UV-C chamber. We offer solutions for small to medium-sized businesses and office areas. Our products are manufactured in Europe, with branded components and ozone-free quality lamps. Air disinfection instead of lockdown – increase safety with rational action, make working life possible, secure livelihoods.

UV-RADIATION AS A LONG PROVEN MEANS AGAINST VIRUSES AND BACTERIA
The use of UV radiation against pathogenic microorganisms such as viruses, bacteria, yeasts and fungi has a long history.
Former scientist Von Recklinghausen used UV radiation to desinfect water as early in 1906. In 1937 its use in the air supply system of a school was the first to dramatically reduce the incidence of measles.
For more than 40 years now, UVC radiation has been used in large pharmaceutical products and surfaces to combat a number of human pathogens.
WORKING METHOD
The part of the UV spectrum relevant for air disinfection is specifically the UV-C subrange between 200-280nm.
The peak power of UV-C low-pressure lamps is 254nm and thus very close to the optimal range for DNA/RNA absorption by micro-organisms.
This is where the maximum killing / inactivation takes place. The radiation has a germicidal or, in the case of viruses, inactivating effect, and the genetic information for reproduction is destroyed.
Depending on the microbial group and relative humidity, the necessary dose of UV-C radiation in J/m2 for killing / inactivation varies.
Viruses are the easiest group to reduce; fungal spores can require a hundred times the dose of a virus.
In the figure on the left the necessary dose as an average value of the microbial groups for a killing / inactivation of 90% in air with low / high relative humidity.
The inactivation / killing of viruses and germs in aerosols also requires proven lower doses than on surfaces or in water.
Depending on the complexity of the micro-organisms and the surrounding protective covers, lower or higher UV-C doses are necessary to achieve inactivation / killing.
The aim is to damage the DNA/RNA so that no further reproduction can take place.
SARS-CoV-2 as a trigger for COVID-19 is no exception to the inactivation of viruses by UV-C. Recent laboratory tests confirmed the inactivability at a rate of 99% at a UV-C dose of 5mJ/cm2 on surfaces.
In the right dose UV-C is equally effective against viruses that cause influenza, measles, mumps and tuberculosis bacteria. It does not always have to be a pandemic, even though UV-C has already been and still is successful against precursor corona viruses SARS-CoV and MERS-CoV, and all the numerous known types of corona virus can be inactivated by UV-C without exception. Decentralised UV-C air disinfection therefore has lasting practical value!
