Niels Finsen, a brilliant Danish medical student, was afflicted by a curse: a degenerative dementia of the frontotemporal lobe, which would shortly be called “Pick’s disease”.
Niels was also tenacious though, as well as endowed with enormous scientific curiosity.
He discovered, during those afternoons of forced sunbaths prescribed by his doctor, that the direct rays gave him energy; he therefore decided to study the phenomenon scientifically.
Thus, after years of data, exposure and first-hand experiments, he opened the way towards the discovery of ultraviolet rays, and the ability they had to deactivate the DNA of bacteria, viruses and other pathogens, destroying their ability to multiply and cause disease.
Well, now let’s jump forward in time. And let’s change the subject: let’s talk about the use of UV lamps in the catering sector.
Specifically, of UV-C lamps in air-extraction!
UV-C light, as can easily be understood from the premises, inhibits the growth and reproduction of germs and bacteria.
The exhausted air is irradiated by UV-C lamps, mounted near the filter battery. These lamps, integral with the fan, sanitize and reduce the number of airborne microorganisms.
But there is more: the emanations of UV-C rays, in contact with the air, generate ozone.
This, in addition to acting as a further bactericide, eliminates the bad odour produced by the air expelled from the cooked fat.
The air now passes through a TIOX filter. This one, thanks to its titanium dioxide coating, increases the effectiveness of the germicidal effect of the lamps.
Titanium dioxide is in fact a photo-catalyst, which slows down the flow of exhaust air, increasing the contact time.
