Core Water Softener, 11 to 24 Liters
Premium Water Softeners
Ecosoft CORE water softener
Performance · reliability · smart management
The new generation of Ecosoft CORE water softeners combines advanced volumetric technology, energy efficiency, and compact design for optimal protection against limescale.
Why install a water softener ?
Protection for your equipment and everyday comfort
- Protects your household appliances against scale buildup
- Extends the service life of your water heater, washing machine, and faucets
- Improves how your skin and hair feel
- Reduces household cleaning product use
- Optimizes your energy efficiency
- Protects your plumbing system
CORE technology : smart operation
Ion exchange water softening
Hard water passes through an ion exchange resin that captures calcium (Ca²⁺) and magnesium (Mg²⁺), which cause limescale, and replaces them with sodium ions (Na⁺). The outgoing water is softened and provides lasting protection for your system.
Automatic volumetric regeneration
Unlike conventional timer-based systems, the CORE range triggers regeneration based on the actual volume used. The result : less water and salt waste.
- Optimized consumption
- Smart automatic cycle
- Built-in backwash function
- Reliable, precise, high-performance valve
Ecosoft DV control valve
Maximum reliability
The Ecosoft DV valve features diamond-coated ceramic discs, ensuring exceptional precision and increased wear resistance.
- Smooth, long-lasting operation
- High resistance to impurities
- Greater reliability than standard valves
- Can be installed without a pre-filter
- Reduced maintenance
Technology designed to ensure years of operation without loss of performance.

Frequently Asked Questions
Everything you need to know about your Ecosoft CORE water softener
How can I tell if my water is hard?
White deposits, spots on dishes and rapid scale buildup in your water heater are the most common signs. A total hardness (TH) test lets you measure hardness accurately.
Can I adjust the residual hardness?
Yes. The built-in blending valve lets you adjust outlet water hardness.
How often does regeneration start?
It depends on your water consumption. The system automatically calculates the optimal time.
How long does the unit last?
With regular maintenance, a CORE water softener can operate for more than 15 years.
