SITA UV Disinfection Units – Rack 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 – Rack 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.

  • Configuration: Z shape
  • Mounting: vertical (preferably) – ask for horizontal configuration
  • Connection: threated connection (UV 550 – UV 700- UV 750 – UV 800)
  • flanges PN 10 (UNI EN 1092 -1) (80/4 and 80/5)
  • UV sensor holder : Stainless steel 316L
  • UV sensor: selective sensor (option: DWGV or Ö-Norm Sensor)
  • Seals: Silicone and Viton
  • Automatic Cleaning system: possible on all the models – optional

Manual Cleaning System RM (Optional)

SITA manual cleaning system is available on all models.  It consist in a rack with special teflon oring that cleans the quartz sleeve going up and down. The cleaning operation can be done by the operator during the normal function of the system.

Automatic Cleaning System RA (Optional)

SITA automatic cleaning system is available on all 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.


  • Configuration: U shape
  • Mounting: Horizontal
  • Control Panel: DS Plus series with UV Cube monitor


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).
