Desar-3 is a closed type irradiator. The source of ultraviolet radiation is ozone-free lamps with a wavelength of 254 nm. UV radiation with a specified wavelength has a wide spectrum of action on microorganisms, including bacteria, viruses, fungi and spores.

In 2005, research was conducted at the Research Institute of Influenza RAMS on evaluating the effectiveness of the use of the irradiator - recirculator DEZAR in the treatment of influenza and the prevention of influenza and other acute respiratory viral diseases. Place of testing: preschool institution located in the suburbs of St. Petersburg. Under observation were children 3-7 years old, the total number of observed was 67 children. 2 observation groups were formed - main and control. In two game rooms with an area of ​​25-28 m2 in the middle of February 2005, two devices were installed. Schedule for switching on devices: 5 days a week - from Monday to Friday in the presence of children during the entire time they are in the room, as well as the irradiator - recirculator turned on 30 minutes before the children arrived and turned off only 1 hour after they left. As a control, children were observed in 2 similar playrooms in which UV irradiators were not installed. Test Results:

1. Children aged 3 to 7 years were monitored daily by a pediatrician. Objectively, the negative effect of the apparatus on children, as well as complaints from children, were not noted.

2. During the use of the device, the total number of sick children in the groups where the devices were turned on turned out to be 1.5 times less than in the similar control groups. Since cases of chickenpox were noted in the institution during this period, these indicators were also analyzed. With this infection, the effect of using the device was more pronounced, amounted to 1.8.

Practical use of Dezar-5 records 50 minutes required for 99.9% disinfection of a flu contaminated 74 м3 room.

Especially effective is the use of Dezar-3 during a dangerous epidemic situation. Dezar- prevents the spread of infections such as influenza, acute respiratory infections, diphtheria, tuberculosis and many others by disinfecting indoor air. In addition, scientists have found that the SARS virus, an epidemic of which has swept almost the whole world, is sensitive to ultraviolet radiation, which means that Dezar- is effective in controlling the spread of this disease.

The recirculator is intended for air disinfection of rooms of all categories: medical and preventive facilities (operating rooms, burn wards, medical rooms, wards, etc.). It can be used as a final link in the complex of sanitary and hygienic measures in preparing the premises for work, but its main task is to work in rooms where constant maintenance of aseptic conditions in the presence of people is required.

The recirculator is also intended for use in rooms with an increased risk of the spread of diseases transmitted by airborne droplets and by air.

Until recently, the release of such devices was not possible due to the lack of ozone-free lamps. Now such an opportunity has appeared. The Dezar-3 recirculator uses ultraviolet ozone-free lamps.

Lamp bulbs have a special coating, which, delaying radiation shorter than 200 nm, prevents the formation of ozone in the air and at the same time increases the lamp life up to 9000 hours.

Lamps create sufficient radiation to destroy all microorganisms present in the room (air disinfection efficiency, depending on the recirculator model, is 95-99.9%).

High-power UV radiation destroys biological and organic compounds, while removing the corresponding odors and tobacco smoke.

The absence of direct UV rays and ozone makes DEZAR recirculators absolutely safe for use in the presence of people.

Bactericidal recirculators DEZAR-3 provide the highest degree of disinfection (99.9%) and meet the highest requirements for air conditions in operating rooms, burn and intensive care units, maternity wards, i.e. where complete sterility is required.
