Volume Controlled, up to 120 m3/h Series STFA

UTILITY

Water softeners are used in order to remove the total hardness of the water and to produce the so-called soft water. This is achieved by passing the water through ion-exchange resin bed, which exchanges the ions of Calcium and Magnesium with Sodium. When the resin becomes saturated, it is regenerated by means of salt solution (Sodium Chloride – brine).
The product water – free of hardness – does not cause salt scalings and the entire equipment that uses this water is thus protected.

 

COMMON APPLICATIONS

  • Feed water for boilers or cooling towers.
  • Total hardness reduction in water for general use running through distributing networks (industries, hotels, hospitals, buildings, residences etc).
  • Any application which requires soft water.

ADVANTAGE

  • Fully automated operation / possibility for manual regeneration according to the user’s will.
  • Automation operates on low voltage (12 Volt) for the personnel’s protection.
  • Minor pressure drop.
  • Minimum maintenance cost.
  • The resin tank is coated with high-density polyethylene, thus it has a high endurance against corrosion.
  • Electronic control panel.
  • Selection of the day and time of regeneration.
