UVCs
Ultraviolet UVC radiation (200 to 280 nm) deactivates bacteria and viruses by attacking their DNA. Their genetic information is destroyed. Micro-organisms lose their ability to reproduce and are annihilated. These viruses and bacteria are unable to develop immunity to UV-C rays.
What are UVCs?
One component of the electromagnetic spectrum, ultraviolet light, has a shorter wavelength than visible light. Infrared and X-rays are examples of other wavelengths of the light spectrum that are also invisible.
There are three types of UV light: UVA, UVB and UVC. UVC light has a wavelength range from 100 to 300 nm, but micro-organisms are particularly sensitive to light in the 240-280 nm region.
The energy of UVC light damages DNA and prevents micro-organisms from proliferating. The disinfection bulbs in our solutions emit UVC light, which has the most powerful disinfectant effect, with a wavelength of 254 nm.
History of UVC
UV-C radiation has been used as an air, surface, object and water disinfectant since the early 20th century. To date, all viruses and bacteria tested in laboratories continue to be annihilated during disinfection by UV-C light.
1903 - Niels Ryberg Finsen was awarded the Nobel Prize in Medicine for being the first person to use UV light to treat disease. In the 1950s, the Finsen curative lamp he created was used successfully.
1908 - UV-C was used to disinfect Marseille's municipal water supply.
1930 - Westinghouse created the first UV-C germicidal lamps for commercial use. They were mainly used in hospitals.
1950 - UV-C was added to air treatment machines. They played an important role in the prevention and eradication of tuberculosis.
2020 - DT-Solution began its efforts to combat the sudden COVID-19 pandemic with up-to-date, under-utilized UVC technology. At a time when demand for disinfection has exploded, DT-Solution has made it more sustainable, less expensive and more effective.

DTS is constantly improving proven technology to better meet our customers' needs and move towards safer, greener and more efficient solutions.
- 5 to 30 minutes of radiation per room guarantees eradication of 90-99.999% of bacteria and viruses.
- No chemicals, solvents or gases are involved.
- No harmful or caustic residues are left behind.
- The room can be occupied immediately after treatment.
- DTS products are calibrated to destroy 99.99% (LOG4) of all major viruses and pathogens.
- Tests showing their effectiveness on COVID have been carried out by Boston University.
- Ultraviolet radiation, at a precise wavelength of 254 nm, photochemically destroys the DNA of micro-organisms, thus halting their reproductive process and rendering them non-pathogenic.
- Used in many hospitals, UV-C disinfection has proven its effectiveness against germs and bacteria.
- Most pathogens are exterminated very quickly. For maximum effectiveness, all surfaces to be treated must be exposed to the rays, avoiding shady areas.
- UV-C is part of the UV family, and as such, exposure to UV-C is regulated.
- The maximum doses/exposures authorized per day are regulated by an international standard, ISO 15 - 858.
- Exposure of humans, animals, plants and vegetation to UV-C rays is therefore prohibited.
- All our products have been developed to ensure the safe use of UV-C.
- For NanoPur-T, the maximum daily dose authorized at one meter is 15 seconds, 4 minutes at 4 meters. UV-C is harmless behind glass or polycarbonate.
