Key advantages
Super-compact, space-saving structure: the perfect solution for apartments and small spaces. The system takes up minimal space in the cabinet (only 55.4 cm high) without compromising softening power.
2-in-1 system (softening and iron removal): beyond a complete solution to the problem of hard water and limescale, the system efficiently removes especially high iron concentrations (Fe up to 10 mg/liter), preventing brown stains and rust in the plumbing and sanitary fixtures.
Savings of up to 60% in salt and water: thanks to a unique tank design and an especially fine, dense ion-exchange resin bed (Super Fine Resin), the system makes maximum use of the salt and requires significantly less water and salt for regeneration.
Patented dual-core valves: a smart digital control valve with a unique structure ensuring continuous water flow, reliable trouble-free long-term operation and preventing water waste to the drain.
10 times longer life than usual: the ion-exchange resin in this system is chlorine resistant and lasts 10 times longer than resins in typical water softeners, keeping maintenance costs to a minimum.
Green and internationally certified: operates at full efficiency even at low feed pressures, has a fully recyclable body and tank, and carries the strict international NSF quality certification.
