Biocide-free drinking water purification system ISIWater Health AU-UVC - Made in Germany -

UV systems eliminate 99.9 % (log 3) of germs in drinking water using UV radiation with a wavelength of approx. 270 nm.

However, these systems only work if the flow rate is limited, the transparent pipe carrying the water is not covered with limescale or other deposits, the UVC LEDs are in operation and a minimum dose of 10 mJ/cm2 is achieved.

Furthermore, despite the elimination of germs, residual germs as well as protein and DNA residues remain in the drinking water and are consumed. What effects the DNA residues could have on body cells is still being investigated.

Our ISIWater Health AU-UVC system eliminates these disadvantages so that the drinking water is reliably germ-free to 99.99999 % (log 7) at all times.

The AU-UVC system consists of a UVC element, which is connected in parallel to the pressure pump, an activated carbon filter and an ultrafilter. The UVC element switches on when the pressure pump is running and eliminates 99.9 % of germs. The activated carbon filter removes pollutants and chlorine. The ultrafilter removes any residual germs and protein residues. The drinking water is then 99.99999 % (log 7) germ-free and 90 % contaminant-free. The flow rate is approx. 4 liters per minute. The energy consumption of the UVC element is extremely low at 3 watts per hour. The UVC element has a service life of approx. 70,000 liters, the activated carbon filter of approx. 10,000 liters and the ultrafilter of approx. 20,000 liters. We recommend changing the activated carbon filter every year. The water-carrying tube of the UVC element can be cleaned or descaled at any time if necessary. The connection fittings can be removed for cleaning purposes
