Environmentally friendly water treatment

Sustainable water treatment for the best water quality – maintenance-free, chemical-free, and environmentally friendly.

The AQUABION® (trademarked name) limescale converters offer innovative water treatment for your home or business. Our limescale converters do not require chemicals or electricity and can be installed in the existing water pipes quickly and easily.

Instead of conventional lime filters, you can now rely on innovative AQUABION® limescale converter technology. 

Limescale and rust are responsible for most of the water damages and wear of household appliances in Germany. 

Neutralized limescale protects your home and extends the service life of your water pipes. Where conventional lime filters remove lime (and thus taste) from the water, AQUABION® limescale converters offers a modern alternative: The clever design of the device modifies lime so that it doesn’t adhere anymore. It remains in the water and thus maintains the natural taste of your drinking water.

Furthermore, AQUABION® limescale converter can reduce your water consumption and energy costs.

Even 1 mm of limescale deposits on heating elements and heat exchangers can consume up to 10% more energy and water. At 2 mm, already up to 25%. 

Your water hardness needs an individual solution, please contact us for this and we will work out an individual solution for you.

As soon as the water flows through the AQUABION® limescale converter, it starts to unfold its effect.
