Demineralized water is completely pure water, devoid of all minerals. The amount of substances in the water can be tested with the TDS (total dissolved solids) meter. Its purity level is given in PPM (parts per million). If PPM is 0, the water is completely demineralized. Fully purified water provides fantastic results when cleaning windows and facades – it reduces electrostaticity, cleans well without chemicals, leaves no streaks and stains after evaporation. The Water Fed technology is used to wash glazing, photovoltaic panels, advertising pylons, blinds, metal structures and smooth facades up to a height of 24 meters.
