Valdo-Technic - Automatic Air and Surface Desinfector

UV technology

Ultraviolet-C, or UV-C for short, is electromagnetic radiation with a wavelength smaller than visible light but larger than X-rays, in the range between 200-280 nm. This radiation has a germicidal effect: micro-organisms (viruses, bacteria, moulds) exposed to UV-C light become inactive within seconds.

The purifying effect of UV-C light is based on a photochemical process. UV light destroys the DNA of viruses and bacteria, thus preventing them from reproducing. It also damages other cellular components, effectively destroying these micro-organisms. The effectiveness of UV-C depends directly on its intensity and the time of exposure.

UV-C radiation is most effective in killing viruses and bacteria at 264nm.

The light from UV-C lamps is emitted at 253.7 nm, which is very close to its peak (264 nm) and is the most destructive to micro-organisms. UV-C lamps are therefore excellent for cleaning liquids, surfaces and air.

The 254nm radiation of UV-C/germicidal lamps is effective in killing micro-organisms (viruses, bacteria, fungi) and is therefore also effective in the fight against COVID-19, among others.

The air sterilisation equipment provided by Valdo Technic offers an effective solution for the elimination of airborne viruses.

The device first separates solid airborne contaminants and in a second phase, it uses powerful UV-C radiation to destroy pathogens that have passed through the filter.

Using the UV-C light source selected by Valdo Technic, a 99.92% germ elimination rate is achieved.
