softliQ:SD23 – Your leader in terms of design and performance.

The water softener softliQ:SD23 (Application recommendation: 1 to 12 people) softens water according to the water consumption. The system capacity is automatically adapted to the individual water consumption of the user. A continuous supply of soft water is always guaranteed When at least 50% of the current system capacity is used up, the softener regenerates once a day at a time when no water is required. The softliQ:SD23 system operates according to the ion exchange principle and features a fully automatic control unit, as well as a wear-optimised control valve. Based on the set raw water hardness and the water withdrawals, the water softener adapts to the conditions prevailing on site. Technical intelligence ensures efficient softening with the lowest salt consumption. The comfort mode is factory set. In case of significant fluctuations in the water consumption, however, it is possible to switch to the Power Mode. The system is operated via the integrated colour touch display or via Grünbeck's myProduct app.
