4.3 Principle of operation in disinfection mode
The UV-C lamps used in the device emit radiation of a strictly defined wavelength of 253.7 nm. It is a wavelength that has
a photolithic effect on microorganisms such as bacteria, moulds, yeasts and viruses. Ultraviolet light of this wavelength
effectively penetrates their cell membrane destroying the structure of their DNA and thus preventing their reproduction.
Subjected to high levels of UV-C radiation, microorganisms and viruses are permanently destroyed. In addition to the
disinfecting effect of the UV-C radiation used, we also obtain a high quality deodorising effect (removing odours from the
air). Due to the special design of the UV-C chamber, the device operating in disinfection mode can be used in rooms where
people are present. Specially designed light traps inside the device completely prevent invisible, harmful UV radiation from
escaping from the device. The specially selected type and high power of the UV-C light source with a selective emitted
wavelength of 253.7 nm, and the unique solution of the double quartz filter UV-C lamp used in STERYLIS sterilisers,
causes the harmonic components of the ozone-producing UV light emissions below 240 nm to be blocked inside the lamp.
Thus, in disinfection mode, the STERYLIS BASIC sterilizer does not produce any harmful ozone at all and is completely safe
for the people around it.
