Air, water and surfaces usually contain a large amount of germs. Some are harmless, while others can cause a serious health risk for people.
The microorganisms present in the air - such as viruses, bacteria, yeasts and moulds - occur particularly in heavily frequented areas such as airports, doctors' surgeries, hospitals and in industry. They endanger the health of people, contaminate raw materials or spoil food.
UV radiation reliably reduces germs and improves hygiene and storage conditions. To reduce the level of germs in the long term, the germ-contaminated air can already be disinfected in the supply air ducts.
The short-wave UV radiation in particular has a strong bactericidal effect. It is absorbed by the DNA of the microorganisms and destroys their structure. In this way, the living cells are inactivated.
