UVC lamps have been used for disinfection for decades. When a virus infects a host, it uses RNA or DNA to replicate, this is how it grows in number, trying to overwhelm our immune system and later spread to a new host. The energy of UVC light interacts with DNA and RNA altering its structure so that it does not function.
Stability of SARS CoV-2 on surfaces. While there is a decline, it remains reasonable stable (10% remaining) for 40 hours.
Advantages and limitations with UVC for disinfection
IUVA Fact Sheet on UV Disinfection for COVID-19
The International Ultraviolet Association (IUVA) believes that UV disinfection technologies can play a role in a multiple barrier approach to reducing the transmission of the virus causing COVID-19, SARS-CoV-2, based on current disinfection data and empirical evidence.
Handheld UV device for surface disinfection
UV BARx1 is a powerful and easy-to-use handheld disinfection device. It can be used in many areas for disinfection such as a keyboard, copiers, handrails on stairs, coffee machine or anywhere people often touch their hands.
UV box for surface disinfection
UV BENCHx1 is designed for disinfection larger products with corners and cracks where cleaning and dispensing can be difficult such as toys, soccer balls, tennis balls, tools etc. Within less than a minute, a 99% disinfection of most common bacteria and virus can be achieved on the outer surfaces.
We have developed W-LED and P-LED and we are distributor of air-cooled UV-LED systems from Excelitas Technologies.
The UV-LED technology is a robust and, above all, efficient technology of the future to cure inks, coatings, silicones and adhesives with UV light, which offer great potential for the printing and coating industry. UV-LEDs can be switched on and off instantly in line with operation cycles, so energy is consumed only when necessary. This makes the advantage of the LED technology clear: the service life of the LEDs is equal to the actual usage time. This makes UV-LED light sources substantially more efficient and economical in cycled operation.
