Ultraviolet Germicidal Irradiation
How Does It Work?
Ultraviolet germicidal irradiation is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UVC) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.
Ultraviolet(UV) light is a component of the electromagnetic spectrum that falls in the region between visible light and X-rays. This invisible radiation includes the wavelength range of 100-400nm. UVC light covers the spectrum between 200nm and 280nm. Because of the spectral sensitivity of DNA, only the UVC region demonstrates significant germicidal properties.
UVC light is weak at the Earth’s surface since the ozone layer of the atmosphere blocks it. UVC devices can produce strong enough UVC light in circulating air to make them inhospitable environments to microorganisms such as bacteria, viruses, molds, and other pathogens
99.9%
Ultraviolet Germicidal Irradiation kills 99.9% of all bacteria, germs and viruses.
The application of UVC to disinfection has been an accepted practice since the mid-20th century. It has been used primarily in medical sanitation and sterile work facilities. Increasingly, it has been employed to sterilize kitchens, office space, public transport, work surfaces, malls, schools and public spaces.

Disinfection for Coronavirus
A Global Pandemic
As the global pandemic continues to cause unprecedented disruption to businesses, particularly within the hospitality and tourism sectors, we know that once the world opens up again, it will take time for businesses and markets to recover.
For some time, people will have a level of uncertainty and fear associated with international travel and it will be of high importance for businesses to instil confidence and adopt further measures to reassure customers’ safety.
UVC disinfection is a simple, efficient, economical and environmentally friendly way to create safe and clean rooms and environments for guests and staff, teachers and students, chefs and service staff, healthcare professionals and patients, employees and customers.
