SITA UV Disinfection Units – LCD Series

SITAUV since 1982 is an Italian company leader in the UV market. From domestic to municipal application, industrial solutions, swimming pool disinfection, there is a SITA unit for every application.

SITA UV – LCD Series

S.I.T.A. UV system emit an UV-C irradiation with λ=254 nm; this wave length causes an alteration of some chemical links present among nucleotids so that the information contained and conveyed by DNA of every organism present in the water change.

These alterations lead to the cellular death and so to the bacteriological elimination.  This disinfection system has a physical working principle and not chemical. Nothing is added to, not taken away from water; in this way there is no formation of undesired by-products even in case of overexposure, in the full respect of environment. The time of interaction water-radiation is of few second; the disinfection directly takes place only during the passage of water. For this it is necessary to install the UV-C system after any other treatment.

Stainless Steel Reactor:

The UV reactor is totally in stainless steel AISI 304 or 316L internally/externally polished; the stainless steel of its chemical/physical characteristics is particularly suitable for the treatment of primary waters, and being polished also in the internal part it is completely without porosity that could favour the keeping of spores; moreover, being glass polished, the germicidal action of the lamps is increased.
