Mobile UVC disinfection units have been in use as a method for air and surface disinfection for over 50 years. There are a variety of UVC mobile disinfection units available in today's marketplace, many with claims about extremely fast disinfection times. UVC dose = UVC intensity x time, and corrected for distance.
When considering a mobile UVC disinfection unit, run times are considerably different when addressing various microorganisms.
American Ultraviolet's mobile disinfection units have a center lamp tower with lamps mounted vertically, emitting energy at 360 degrees. These units will flood the entire space with disinfection energy, and cover the same area, just differing in cycle time and unit features.
Let's take a closer look at the differences when considering one of American Ultraviolet's mobile UVC disinfection units. The chart on this web page (click the image to see it larger) provides a quick comparison of UVC dosage delivered at various distance. This data shows average UVC dose values based on third party measurements, and in-house engineering evaluations during product validation.
So, what should you look for when selecting a UVC mobile disinfection unit?
The most important consideration is, generally, speed - how long does it take to disinfect?
"UVC Horsepower" (or UVC intensity), which can be thought of as the higher the intensity the faster the run time for a target dose.
Let's consider the following example of some typical cycle times for American Ultraviolet's mobile UVC fleet. If the inactivation dose required is an estimated 6.6 mJ/cm2 based on studies. At 10 feet distance, the device run times are estimated at:
ARTZ 2.0 < 30 seconds
MRS-45 < 1 minute
MRS-33 < 2 minutes
MRS-14 ≈ 10 minutes
The UVC energy delivered at various distances can be estimated based on testing data; and validated with radiometers or photochromatic ink indicators (often referred to as Dosimeters).
Applications are endless, and therefore mobile UVC units are found operating in healthcare and educational environments, office buildings, gyms, daycares, restaurants, and government buildings, just to name a few.
