UV-STICK allows deep air and surface disinfection in any type of health and pharmaceutical environment. Traditional cleaning methods are, often, not sufficient to ensure high levels of hygiene, which can be achieved only by the use of UV-C technology. As a matter of fact, in the health and pharmaceutical sector, all the environments need to be disinfected to keep hygiene standards high. With UV-STICK, it is possible to perform a deeper disinfection of all the rooms, in a simple, immediate and safe way, without developing heat, without using liquids and without any contraindications or resistance. UV-STICK is equipped with one or due UV-C lamps, and it applies as a common ceiling fixture. The device can be switched on during work breaks, always when the staff is not present, so it radiates surfaces, which are then disinfected. In environments, the natural recirculation of the currents also allows air treatment, which, purified by the microbial load, creates a perfect and healthy environment. It is shown that the control and the increase of hygiene level allows a consequent and general increase in quality both in healthcare facilities but also in pharmaceutical sector, in microbiological laboratories, etc. The disinfection level with UV-STICK achieves the elimination (99%) of bacteria such as Bacillus, Coli, Clostridium, Legionella, Vibrio, Salmonella, Pseudomonas, Staphylococcus, etc. in just a few minutes of operation. High disinfection levels of UV-STICK can be otherwise achieved, but only with chemicals, hazardous to health and harmful to the environment, as well as costly.
