Softening system for reliable high soft water consumption

The largest German manufacturer of mackerel, herring, and smoked fish relies on our new DHC-Soft4Multi-4200 FE water softening system – a powerful softening system that ensures a continuous supply of softened water with minimal space requirements. Ideal for sensitive applications with high water demand.
With a nominal flow rate of 42 m³/h and a capacity of 1,400 m³ x °d per column, the DHC-Soft4Multi-4200 is ideally designed for industrial requirements. In parallel operation, three of the four columns are active, while the fourth is automatically regenerated – without interrupting the supply of softened water. The integrated savings salting ensures particularly resource-saving operation.A multicolored illuminated display shows all operating states at a glance. The intelligent microprocessor control enables quantity-dependent regeneration, an optional salt shortage warning, and the storage of all operating data for 63 days.
With the DHC-Soft4Multi-4200, we offer a reliable, efficient, and future-oriented solution for the highest water quality – specifically for sensitive applications.
