The sustainable water treatment
without chemicals Made in Germany.

Sialex®
focus on fluids

The Sialex®Ring offers a sustainable, environmentally friendly solution for water treatment that works completely without chemicals. Thanks to its purely physical mode of action, it reliably removes limescale deposits, rust and biofilm in your pipes and appliances.

It uses acoustic vibrations to change the crystal structure of limescale, for example, so that existing deposits dissolve and new limescale cannot adhere in the first place.

The Sialex®Ring is not only particularly durable, but also completely maintenance-free – ideal for private households and industrial applications.
