UV irradiation has been used for disinfection purposes for quite a long time already. Well recognized are mercury vapor lamps, quite like their flaws.
The plasma-optical xenon technology is a completely new approach to UV disinfection. Here are only a few advantages:
First, pulsed xenon lamps contain only the environmentally safe gas – xenon – which is widely used for general anesthesia, whereas mercury vapor lamps contain a highly hazardous and toxic substance, demanding special measures when broken or disposed of.
Second, Yanex units are ready for operation immediately after turning on. They do not require any heating-up time, quite unlike mercury vapor lamps.
Third, the irradiation spectrum of xenon lamps is continuous, similar to that of the Sun and it covers the whole ultraviolet region from 190 nm to 400 nm, whereas the mercury lamps irradiation spectrum is essentially monochromatic (λ=254 nm).
Fourth, the nature of the impact is fundamentally different. The pathogens are inactivated by powerful light pulses (the intensity of a xenon lamp light is 1 000.. 10 000 times higher than that of mercury vapor lamps).
Further still, plasma-optical xenon technology possesses a number of unique features:
- The synergy of inactivation mechanisms for all the basic structural cell elements and macromolecular organic matter (proteins, fats, nucleic acids etc.) leads to reducing threshold germicidal doses, causes cell death and ensures high efficiency of air and surfaces disinfection (up to 100%).
- Decreased activity of repair processes caused by UV irradiation ensures high biocidal efficacy. The activity of pulsed ultraviolet affects all microorganism types including hospital and drug-resistant strains of bacteria, mycobacteria, spores and mold fungi.
- Multiple reduction of bactericidal doses, high capacity and constant operational readiness of pulsed xenon lamps (no warming up time required) allow to disinfect a room in a matter of minutes.
- High intensity of pulsed xenon lamps irradiation (100,000 times more intense than the light of LP mercury vapor lamps) allows for widening the effective area of pulsed units almost indefinitely. Pulsed UV units are able to disinfect large rooms.
- High reliability of disinfection is achieved due to an intermittent irradiation mechanism and control of the bactericidal dose by a built-in UV sensor.
- Absence of mercury in pulsed xenon lamps and anti-ozone protection ensure environmental friendliness of disinfection.
- High vibration and impact resistance of pulsed xenon lamps ensure mobility and reliability of the units.
- Operation capability in a wide temperature range from -30° to +30°С significantly widens the application range of pulsed units.
