“Izumrud-SI” (model 01os) is a universal installation which produces ionized drinking water of the highest quality with set mineral composition (microelements: Са++, Mg++, Iodine) and antioxidant effects (pH, negative redox potential, microclusters). The installation is equipped with built-in controller, display, three flow-type transducers with two-level indication system to track the work of the following systems: osmosis (purification), activation (water ionization), drinking water mineralization (optimization of mineral composition).
