SITA UV Disinfection Units – AM 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.

AM Series

S.I.T.A. UV system emit an UV-C irradiation with l=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.

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.  To make the maintenance and inspection operations easier the chamber is openable at one side.

Chemical Cleaning System RA (Optional)

SITA chemical cleaning system is available on all the models and can be used together the automatic RA system. It consist in a special tank (depending from UV reactor volume) with pump motor on the top connect to the UV reactor. In this way the chemical product (depends from Pollution) will clean not only the quartzes but the whole reactor. This cleaning system is recommended on all the UV of this Series and wll integrate the automatic wiping (if present)

Automatic Cleaning System RA (Optional)

SITA automatic cleaning system is available on all the models. It consist in a rack with special teflon oring that cleans the quartz sleeve going up and down.  This movement is given by a programmable SITA UV cube monitor that moves a motor shaft placed on a side of the system. For these reason all the system with RA option have a horizontal design.  Time and days of the cleaning can be easily set on site.
