Light emission at the particular wavelength of 254 nm is the base of disinfection systems with ultraviolet light UV C treatment. It’s, infact, this particular wavelength that allows to inactivate the DNA of microorganisms by inhibiting their ability to proliferation and therefore contamination online
The UV light, in general, is a part of the natural spectrum of sunlight emission. UV radiation is then divided into four sub-categories according to the radiation wavelength: UV-A, UV-B, UV-C and UV-Vacuum. Among the wavelengths of UV light, the one to which the DNA of living organism is most sensitive, is the UV-C one. Living organisms do not have adequate protection mechanisms against ultraviolet rays, as they have been always protected from the ozone layer.
UV-C disinfection systems exploit the effects of this radiation on DNA whose helical chain is interrupted by preventing the replication of the genetic code and therefore, basically, the possibility of the formation of bacterial colonies: the affected microorganism is then inactivated, preventing its reproduction.
The correct design of a UV treatment system therefore focuses on the intensity produced within a finished reaction volume and the contact time in which microorganisms are exposed to radiation.
Besides the standard production lines of Air & Surfaces Division Montagna with its own R&D dept. can study and design UV-C Systems to suit Customers demand.
Montagna UV-C systems can be utilized in the following area:
