The WS Regenerator regeneration system allows the softening cartridges of the water softening units WS 50 and WS 100 to be regenerated and reused multiple times. The WS Regenerator operates on the principle of the ion exchange process in neutral exchange. The regenerating agent is softening salt. Especially with frequent use, the WS Regenerator proves to be the most economical option for producing softened water. The automatic backwash at the control valve is easily activated with the push of a button. The individual phases of regeneration are automatically cycled through at predetermined time intervals by the camshaft.
