- The ORUBp‑3‑3 KRONT (Dezar‑4) air recirculator is intended for continuous air disinfection in polyclinics, hospitals, maternity hospitals, blood transfusion stations and other healthcare institutions. Suitable for operation in the presence of people.
- The DEZAR‑4 unit has high disinfection efficiency — it inactivates 99.9% of microorganisms present in the air. These include pathogens transmitted by airborne and contact routes.
- Radiation source — 3 mercury, ozone‑free bactericidal ultraviolet lamps, 15 W each, types: TUV 15W Philips / LTC15T8 (GI5T8) LightTech / Puritec HNS 15W / Tibera UVC15W / G13 Ledvance / DB15 (NIIS named after A. N. Lodygin) with a nominal bactericidal flux of at least 4.7 W.
- DEZAR‑4 is safe for people in the room; this was achieved by including in the unit design:
— UV lamps emit radiation at a wavelength of 254 nm, which penetrates directly into the nuclei of microorganism cells, inactivating them. Pathogenic bacteria and viruses stop reproducing.
— a special coating for the lamps that prevents ozone formation during operation.
— labyrinth screens that fully reflect the lamps’ light and direct it into the device chamber. These elements prevent radiation from escaping outside.
- High efficiency and complete safety are the main, but not the only, advantages of the device:
— the unit is simple to use and maintain, durable. It is compact and relatively lightweight; its housing is made of impact‑resistant and chemical‑resistant material. The DEZAR‑4 stand is equipped with wheels for easy movement;
— the unit is additionally equipped with a powerful air filtration system — it cleans the air of contaminants and unwanted odors, and smoke;
— the unit’s fans operate silently;
— built‑in filter in the design, and replaceable air and carbon filters included;
— intelligent lamp runtime notification system with a working‑time timer.
- DEZAR‑4 is a powerful, convenient and safe air disinfection device suitable for use in rooms of categories II–V: dental and multiprofile polyclinics, dressing rooms, intensive care units, bacteriological and virological laboratories, blood transfusion stations, barber shops, laundries, beauty and massage salons, schools, kindergartens.
