Continuous Ultraviolet vs. Xenon Pulse UV Disinfection

Not all ultraviolet disinfection is alike. In fact, not all ultraviolet is alike.

The U.S. Veterans Administration commissioned an influential infection prevention research team led by Curtis Donskey, M.D., to conduct an independent study of continuous ultraviolet disinfection vs. xenon pulse UV disinfection that was published in early 2015. The report concluded that “PX-UV was less effective than continuous UV-C in reducing pathogen recovery on glass slides with a 10-minute exposure time in similar hospital rooms.” 

Some UV disinfection systems, like xenon pulse UV, use the full spectrum of ultraviolet light to disperse germ-killing energy. The xenon flash bulbs used in this technology produce 45-50% of their output as visible light and another 10% as infrared or heat. That leaves about 35-40% available to generate UV-A, UV-B and UV-C wavelengths.

Bulbs generating UV-A, UV-B and UV-C wavelengths are inherently less effective in disinfection because it is the UV-C energy that provides maximum germ-killing abilities. The rest is less effective energy.

Continuous light UV disinfection systems, like the IPT™ 3200, IPT 2800 and IPT 1140, maximize disinfection and minimize energy use by utilizing only UV-C rays. In fact, UV-C has been called the “germicidal wavelength” for more than 90 years. 
  

A U.S. Veterans Administration-commissioned study found that continuous UV light disinfection is far superior to xenon pulse UV.
What’s the Difference?
Continuous Light UV Disinfection (IPT 3200)
  • Uses only germicidal UV-C rays for maximum disinfection

  • Higher available power output means faster treatment – use with 20 amp or 15 amp circuits

  • Up to 20x more powerful

  • Single placement, whole-room treatment

  • Designed to kill pathogens in direct, indirect and shadow areas

  • Safest solution – UV-C does not penetrate window glass making it safe for passersby

Xenon Pulse UV Disinfection
  • Uses full spectrum of UV-A, UV-B and UV-C rays -- 40% of UV light used for disinfection

  • Used with standard 15 amp circuits

  • Lower UV-C output provides only spot treatment and requires multiple treatments at different positions in room for complete disinfection

  • Must be repositioned multiple times for direct, indirect and shadow areas


How well did Continuous UV-C perform in the VA study?

“…the UV-C device achieved significantly greater log10 CFU reductions than the PX-UV device.”

“It’s important to note that not only did the continuous UV-C robot in the study show much stronger
disinfectant results, but that it was not run for its entire cycle time.”

 


More Power = Faster Treatment Times & Higher Pathogen Kill Rates
