What is a UVC Light?

UVC lights are ultraviolet lights used to disinfect microbes- “a microorganism, especially a bacterium causing disease or fermentation.” With a significant reduction in microbes, there is a significant reduction in viruses. “Ultraviolet Germicidal Irradiation as used by Federal Agencies such OSHA, NIOSH, GSA, EPA and the CDC when referring to UVC.”

The UVC Cleaning Systems we use are mobile devices. They are durable with Teflon encapsulated emitters, certified and designed to be safe and effective. The units are stainless steel with an impact-resistant thermal plastics construction. You’ll see handles on all four sides that act as crash bars and can be used to pick up and move the device from all directions.

“UVC disinfection devices are regulated by the Environmental Protection Agency (EPA) as a nonchemical pesticide. There currently is no category for UVC disinfection devices with the Food and Drug Administration.”

The device uses 360-degree motion sensing passive infrared (PIR). The ultrasonic technology is designed to create a safe operating environment, however,  the UVC light emits radiation, which is hazardous to your eyes and skin. No humans or animals should be in the room during the disinfection process. There is no ozone emitted from the light but it does condition the air much like the sun does outdoors. UVC devices are systematically similar to an air conditioning including filters, coil, heating core, fan, dampers, and humidifiers and more.  At its peak, the surface of the UVC emitters can reach 180 degrees Fahrenheit during the disinfection but will cool down within seconds after the device is turned off.

Scientifically Speaking 

“UVC is one of many electromagnetic frequencies emanating from the sun. Its properties are unique to its wavelength. To synthesize this frequency, a glass tube is evacuated and refilled with argon at far below atmospheric pressure. Added to this is a small amount of mercury. When the mixture is energized it creates a glowing plasma of electrons that pass through the mercury vapor. As they strike mercury atoms, a mercury electron is liberated at a frequency representative of mercury’s spectral line, which is 253.7nm. The dominant emission (>90%) from these lamps is UV-C energy. The ‘C’ frequency of the electromagnetic UV family has, amongst other things, germicidal effects.”
