Introduction
Xenex’s patented pulse xenon UV disinfection system is a pesticidal device used for the advanced environmental cleaning of healthcare facilities. The Xenex system has been repeatedly shown to integrate smoothly into hospital cleaning operations because of its speed and ease of use.

Product Overview
|
Features Include:
Pulsed-Xenon UV Lamp
Using a Xenon bulb, a powerful, non-mercury form of UV light, combined with a pulse technology that generates high intensity pulses, which makes Xenex the most powerful form of UV-C.
UV Focus System
Uses reflectors and movement to focus UV light towards "high touch" surfaces.
On-Board Database
Logs system activity for utilization tracking and analysis.
Visible Light Filter
Blocks the bright xenon pulse, so that rooms with interior glass can be treated without distraction.
Safety Features
Built in safety timer, emergency stop button, automatic shutdown motion detection system.

The New UV
|
Pulsed xenon disinfection was developed in the late 1970s and represents an advance over the earlier mercury vapor systems (note: if it is not pulsed xenon, then the system uses mercury lamps).
Pulsed xenon UV has a number of advantages over mercury vapor systems:
|
 |
Green:
|
The xenon gas used in our system is inert. We are a certified green technology because the only alternative commercially available means to produce UV for room disinfection uses mercury vapor lamps. Many organizations, including the WHO, have long sought to reduce and eliminate the presence of mercury in hospitals. We help them achieve that goal.
|
 |
Intense:
|
The pulse produced by our patented pulsed xenon system is approximately 25,000 times more intense than the output of a mercury vapor lamp. Because of this, we can penetrate and damage organisms in unique ways. This is especially important as our pulse, because of the intensity, reflects with different properties allowing for our proven disinfection results.
|
 |
Multiple pathways of damage:
|
Not only is the pulsed xenon pulse more intense, it also contains multiple frequencies of germicidal UV. It is known that microorganisms are susceptible to UV damage in the range or 200 to 280 nanometers. Pulsed xenon produces frequencies across this range whereas as mercury vapor systems produce UV at 253.7 nanometers, which has about a 40% efficiency for DNA damage. Because our pulse contains higher energy wavelengths, the Xenex system damages cell walls, cellular structures as well as emits UV at 260-265 nanometers, which is mirrors the peak DNA/RNA absorbency
