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.
