UV Disinfection

Safe, reliable and environmentally friendly

UV disinfection process

Germs in water, in the air and on surfaces are troubling. Intensive UV light effectively and quickly reduces microorganisms.

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.

How does UV disinfection work?

UV disinfection is effective at wavelengths from 200 nm to 300 nm. The UVC radiation emitted has a strong bactericidal effect. It is absorbed by the DNA, destroys its structure and inactivates living cells.
Microorganisms such as viruses, bacteria, yeasts and fungi are rendered harmless within seconds by UV radiation.
If the irradiance is high enough, UV disinfection is a reliable and environmentally-friendly method eliminating the need for chemicals. Moreover, the microorganisms cannot become resistant to UV radiation.

How safe is disinfection with UV light?

UV rays are highly controversial, as they are harmful to the human organism when exposed to direct radiation. In order to nevertheless enable effective disinfection with UV rays, all our devices for air disinfection shield occupants from the UV rays.

UV radiation has been used in the industrial sector for the disinfection of packaging materials, air and water for years without any problems.

Studies prove that UV light destroys germs securely

Heraeus Noblelight has been working for many years with various institutes and research facilities, such as the Fraunhofer Institute. It has been scientifically proven that UV light in an appropriate dose makes germs harmless.

Studies with comparable germs suggest that UV light can also be used against the COVID-19 virus. Several research institutes are already conducting scientific studies in this area.
