Modern ultraviolet radiation technologies offer innovative solutions for disinfecting air, surfaces and even water. One of the most promising areas is the use of 222 Nm excimer lamps. UVL is proud to be able to manufacture these lamps and create devices based on them.
What are 222 Nm Excimer UV lamps?
222 Nm Excimer lamps are UV light sources that use a mixture of krypton and chlorine to generate narrow band radiation. This spectrum falls into the far ultraviolet (Far UV) region, which has proven to be effective in killing viruses and bacteria without harming humans.
One of the key benefits of 222 Nm Excimer lamps is that they are safe for humans. Unlike traditional 254 Nm mercury lamps, 222 Nm radiation:
- Is absorbed by the upper layers of the skin (stratum corneum) without penetrating living cells, eliminating the risk of mutations and skin cancer.
- Does not damage the eyes as the tear film effectively absorbs the radiation.
- Can be used in the presence of people, providing continuous disinfection of rooms.
Studies have shown that even with prolonged exposure to skin and eyes, these lamps do not cause damage, making them an ideal solution for disinfection in crowded areas.
Effectiveness of 222 Nm in pathogen control
Studies by Columbia University, Harvard and other scientific centers have confirmed that 222 Nm UV radiation:
- Destroys the DNA and protein shells of viruses and bacteria.
- Is not susceptible to photoactivation - the process of repairing damaged microorganisms under the influence of visible light.
- More effective than traditional UV radiation (254 Nm), as it affects not only the DNA but also the protein structures of pathogens.
- Reduces the risk of spreading infections in real time by destroying viruses as soon as they enter the air.
Studies in Japan have demonstrated that using 222nm lamps in public areas can significantly reduce the concentration of bacteria and viruses on surfaces. This makes them an effective solution for high-traffic areas.
Applications of 222 Nm excimer lamps
Excimer lamp devices are used in a wide range of applications:
- Medical facilities - disinfection of operating rooms, wards, corridors, without the need to evacuate patients.
- Public places - airports, train stations, offices, schools, shopping centers.
- Transportation - installation in planes, trains, buses.
- Food industry - destruction of pathogens on food handling surfaces.
- Military and defense structures - protection of personnel from biological threats.
- Toilets and public places - increased level of contamination requires constant disinfection, and 222 Nm provides reliable disinfection.
The 222 Nm excimer lamp technology represents a breakthrough in UV disinfection. It combines high pathogen killing efficiency with human safety, making it an indispensable tool in the fight against infections.
