Water softener Klarwod CS AZUR 25 compact — flow 1.9 m³/h

The Klarwod CS AZUR 25 compact water softener reduces water hardness by exchanging calcium and magnesium ions with sodium ions to protect equipment and improve water usability. Designed for installations with limited space, this model provides a nominal flow rate of 1.9 m³/h and is intended for small commercial or residential systems. The unit is suitable for supplying softened water to boilers, heating systems, and household appliances where reduced scale formation is required.

Advantages

The compact design enables installation in tight utility rooms or near service equipment without requiring a large footprint. Ion-exchange softening technology provides a consistent reduction in hardness ions, lowering the risk of limescale buildup in pipes, heat exchangers and appliances. The unit is engineered for easy integration into existing plumbing and offers operational reliability appropriate for small-scale applications.

Suitable for

• Small residential properties and apartments
• Light commercial settings such as small offices or shops
• Protecting boilers, water heaters and heating circuits from scale
• Extending service life of washing machines, dishwashers and similar appliances

Key specifications

• Nominal flow rate: 1.9 m³/h
• Technology: ion-exchange water softening
• Application: point-of-use or point-of-entry for small systems
• Physical characteristic: compact footprint suitable for limited space installations
• Typical use: reduces hardness ions (calcium and magnesium) in water

How to use

Install the Klarwod CS AZUR 25 on the cold water supply line upstream of appliances or heating equipment you want to protect. Follow local plumbing codes for shut-off valves, bypass loop and drain connection. Configure the control settings and regeneration schedule according to the local water hardness and household consumption; initial setup and commissioning should be carried out by a qualified technician. Regularly check salt level and perform maintenance cycles as specified by the manufacturer to ensure continuous softening performance.

Usage recommendations

For optimal results, analyse incoming water hardness and adjust regeneration frequency to match consumption. Use recommended salt type for the brine tank and ensure a reliable drain line. When installing near heating equipment, include a bypass valve to allow servicing without interrupting water supply.
