A number of state-of art technical and performance solutions, incorporated in pulsed ultraviolet units, ensures their advantage over traditional cleaning methods and means
The technology is based on simultaneous air and surfaces decontamination from microorganisms and viruses by high-intensity (25,000 W/cm2) pulsed xenon ultraviolet light of continuous spectrum (190-300 nm), generated by a pulsed xenon lamp.
Pulsed xenon lamp
A pulsed xenon lamp is basically a quartz tube with electrodes welded on its ends and filled with xenon, a harmless noble gas. Due to electric discharge of several thousand ampere, xenon inside the quartz envelope is heated to 10,000-15,000K. The resulting xenon plasma generates a bright flash of light, in spectral structure similar to the Sun. The lamp generates repeating short (10-4 sec) light flashes with the frequency of several hertz.
Biocidal action
It is based on the multichannel impact of continuous spectrum pulsed UV light on all life-critical structures of a bacterial cell, primarily damaging its genetic material (DNA, RNA) and bio-membranes. The UV light of continuous spectrum triggers the following destructive processes.
The synergy of the said mechanisms of microorganisms' inactivation (high intensity and photochemical degradation of DNA molecules and cell membrane) by pulsed UV light of continuous spectrum leads to full microorganisms' destruction with high efficiency (99.9%-100%) within the shortest time (from 30 seconds).
