64 Shielded bactericidal irradiators are designed for disinfecting premises in the presence of people. Disinfection occurs through natural air circulation through the zone of action of the bactericidal lamp radiation, resulting in viruses and bacteria dying from the absorbed dose of UV radiation. The safety of people in the disinfected room is achieved by using a screen in the irradiator, which prevents UV rays from reaching humans.
The advantage of irradiators with a louvered screen over irradiators with a solid screen is the maximum coverage of radiation action (3 parts of the room volume, its upper part).
