The smart, complete and large-scale bio-decontamination of rooms, room air, surfaces and equipment at the push of a button. Fully automatic, safe, effective, environmentally friendly and inexpensive, according to EN standards. The microbiologically tested room and surface disinfection system DiosolGenerator Protec Professional nebulises a special disinfectant made of hydrogen peroxide, optionally with or without silver cations. This combination of active ingredients is ideally suited for disinfection, as it is able to attack biofilms, enables a long-lasting effect (remanence) and 99.99% decomposes into water vapor and oxygen. The DiosolGenerator Protec Professional works fully automatically and is easy to use. The calculated room size (e.g. 50 m3) is set using a volume controller. After switching on the device, the corresponding Diosol broad-spectrum disinfectant is nebulised to an extremely fine cold mist and verifiably eliminates the germs present in the room and on the surfaces.
