Description

Smart filtration duo

Combining softening resin with a carbon cartridge in a single water softener delivers a tangible improvement in water quality from the point of entry right through to the tap. This solution protects both your plumbing system and ensures comfort in everyday use.

The resin effectively softens the water

  • improves water clarity
  • protects the plumbing system and household appliances
  • prevents limescale build-up

The carbon cartridge improves water quality

  • removes chlorine and its derivatives
  • eliminates organic compounds
  • improves the taste and smell of the water

Carbon filter – cleaner water every day

The carbon filter improves water quality by removing chlorine, unpleasant odours and substances that affect its taste. This makes the water more pleasant for everyday use, whilst also providing better protection for your plumbing system and household appliances. Soft, additionally filtered water also means lower detergent consumption and better care for your skin and hair. The cartridge is essential for the water softener to work properly and needs to be replaced periodically (approx. every 1 year).

With the Carbo Duo, simply unscrew the cover using a key, remove the used cartridge and insert a new one.

  • No complicated installation or servicing required
  • Ready in a matter of moments

 

Automatic control unit – complete control and convenience

Enjoy soft water without the need for unnecessary adjustments or monitoring.
The state-of-the-art control unit automatically adjusts the water softener’s operation to match your home’s actual water consumption. Simply set the water hardness and regeneration time once, and the system will ensure the unit operates at its best.
Thanks to upflow regeneration, the water softener works even more effectively, uses less salt and water, and the resin bed lasts longer — which means lower running costs and greater reliability for years to come.
