Water softening ST

Water softening

Classic water softening sets ST consist of separate filter housings with ion exchange resin and salt tank, arranged separately from each other. They are used in cases of high water consumption, mainly in industry. During rinsing (regeneration) of individual sets, the water flow to the user is either closed off or supplied with the original quality. In case of the need for continuous water supply to the user, several such sets are installed in parallel or continuous action softeners of the Krilico SD series are used.

The system is used to reduce water hardness in homes, offices, industrial applications, as well as heating and power systems. The main purpose of water softening is to eliminate excess calcium and magnesium ions, which are responsible for water hardness. Water softening systems help prevent scale formation in pipelines, boilers, and evaporators.

The presented softeners have digital control. Regeneration initiation is freely programmed based on: softened water volume, time, or whichever comes first.

The set includes:

  • Filter housing;
  • Flow distribution system (distributor);
  • Ion exchange resin with different properties;
  • Control valve;
  • Salt tank;
  • Product passport and user manual;
