UVGI Safety

UVGI Safety

When contemplating the use of Ultraviolet Germicidal Irradiation (UVGI) for disinfection of air and surfaces, safety should be your first consideration.  UVGI can cause eye damage, skin burns and even result in skin cancer if the proper protections...
Ultraviolet Germicidal Irradiation (UVGI)

Ultraviolet Germicidal Irradiation (UVGI)

UVGI is an acronym Ultraviolet Germicidal Irradiation and is defined as the use of Ultraviolet wavelengths of light in the germicidal range (200-320nm) for the disinfection of air and surfaces.  The Wavelength ranges incorporate both UVC and UVB spectrums. ...

The Case Against In-Duct UVC Products

Thermostat RegulationEven hear the “click” on a thermostat?  That click is a trigger that, when activated, kicks your AC or heating system into operation.  It runs for a short period of time, satisfies the temperature you have set, then clicks off. ...
Pathogen Deactivation Method

Pathogen Deactivation Method

Pathogens are any microbes that cause infections in humans and animals, including viruses, bacteria and fungi.  Ultraviolet Germicidal Irradiation (UVGI) is commonly used to deactivate (aka inactivate) the DNA and RNA of pathogens, rendering them incapable of...
UVGI Light and Pathogen Destruction

UVGI Light and Pathogen Destruction

UV lamps used in UVGI systems vary widely in size, shape, and power input/output.  They utilize wavelengths in the UVB or UVC range, between 100 and 320nm.  While the most common UV lamps are high intensity discharge (HID) lamps and low-pressure mercury vapor lamps,...
