Complete, large-area hydrogen peroxide cold mist process for automated room, air and surface disinfection. Fully automatic, safe, effective, environmentally friendly and inexpensive. The microbiologically tested room and surface disinfection system DiosolGenerator Standard nebulises a special disinfectant made from hydrogen peroxide and 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% of it breaks down into water vapor and oxygen. The DiosolGenerator Standard 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.
