Sita 400 DS Ultra Violet (UV) Systems

Disinfection UV units of 400 DS SERIES use low pressure amalgam lamps. Amalgam lamps have higher lifespan and efficiency than standard low pressure lamps. Lifespan is around 16.000 hrs and these lamps work perfectly with low and high water temperatures. In this Series of UV system SITA uses powerful lamps that will allow, at the same treated flow rate, the use of less lamps and so on easier maintenance. The horizontal configuration, due to the lamps length, makes the maintenance work very easy.

Automatic quartz cleaning system is available on all the models.

Stainless steel reactor:

The UV reactor is totally in stainless steel 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.
