What is Ultraviolet Germicidal Irradiation (UVGI) and How Does it Work?
Spreading out as it travels (also called radiation), Ultraviolet (UV) energy is a portion of the electromagnetic spectrum (a term used to describe the entire range of light in existence, from radio waves to gamma rays). UV light is invisible to the human eye.
The UV is readily absorbed by the DNA (a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes, and it is the carrier of genetic information) and RNA (which acts as a messenger carrying instructions from DNA for controlling the synthesis of proteins; although in some viruses RNA rather than DNA carries the genetic information of microorganisms).
UVGI can be used to disinfect air, liquids, and other surfaces. UVGI technology works well in HVAC applications as the air is typically blown across the lamp’s surface.
While the various types of UVGI sources have their advantages and disadvantages across various applications, there is no one best source for every application. Much like a craftsman’s toolbox, there are times when a hammer and nails are the best possible tool, but a hammer and nails aren’t a great solution if the goal is to cut a board to a specific length.
