The housing is made of stainless steel AISI 316, which is why the UV-C TECH sterilizer is primarily intended for private pools where salt electrolysis is not used for water disinfection.

Disinfection by ultraviolet radiation is one of the technologies that has recently been used more and more often to improve the treatment of drinking and pool water. The principle of disinfection lies in the photochemical damage of RNA and DNA, proteins, enzymes, or other biologically important macromolecules.

The effectiveness of disinfection depends on the UV dose, the type of UV lamp used, and their arrangement in relation to the flow direction of the drinking or pool water. To select the right type of UV device, it is necessary to determine and ensure the required UV dose, depending on the flow rate and water quality in terms of its transmittance, i.e. the concentration and type of dissolved and suspended substances that affect the reflection or absorption of UV radiation.

Low-pressure monochromatic UV lamps emit UV radiation at a wavelength of 254 nm; the intensity of the emitted UV energy is only at one level and is highly dependent on the temperature of the treated water and the flow rate. As a result, this type of low-pressure UV lamp has only germicidal effects.

The possibility of combining UV radiation with other treatment technologies leads to high water quality. The advantage is lower operating demands, i.e. savings on dosed chemicals, and safe, simple operation in automatic mode. The disadvantage is the possibility of secondary contamination, so UV radiation alone is not suitable for hygienic protection. In practice, it is therefore combined, for example, with chlorination.
