What Grünbeck Wasseraufbereitung does

Grünbeck Wasseraufbereitung is a German family-owned water treatment company founded in 1949 and headquartered in Höchstädt an der Donau, Bavaria. The company develops and manufactures equipment that disinfects, softens, filters, and chemically treats water for residential and commercial/industrial applications, with a portfolio spanning the softliQ water softening line, pureliQ filtration products, protectliQ leak protection devices, thermaliQ heating-system water treatment, exaliQ dosing systems, safeliQ hygiene systems, and sodajet water dispensers. Technology is built on ion-exchange softening, membrane and backwash filtration, and increasingly on connected devices: softliQ units feature cloud connectivity via WLAN/LAN, an iQ-Comfort device-to-device interface, and AI-powered iQ-mode consumption prediction that adapts regeneration cycles to a 4-week rolling usage pattern. The Grünbeck Cloud and myProduct app provide remote monitoring, push notifications, and KI-supported remote diagnostics across the product family. Technical claims are validated by a Fraunhofer Institut / DVGW study and products carry DVGW, ISO 9001, ISO 14001, ISO 45001, DIN EN 14743, and DIN EN 1717 certifications.

The business operates a hybrid go-to-market model. In Germany, sales and service run through 25 regional locations staffed by 360 service employees handling installation, maintenance, and customer support, complemented by a network of certified installer partners (Wassermeister) and regional factory representatives (Werksvertretungen). Internationally, Grünbeck is present in more than 30 countries across Europe, Asia, Africa, and South America through local distribution partners, with dedicated country sites for major markets. Revenue is generated primarily through hardware sales of installed water treatment systems and recurring service and maintenance contracts; pricing is not publicly disclosed and is provided per inquiry through regional representatives. Customer segments are split between residential homeowners (the primary B2C channel) and commercial/industrial buyers, with a secondary channel of trade installers who specify, install, and service the equipment. The company is led by Dr. Günter Stoll as Vorstand (CEO) and Jürgen Weißenburger as Aufsichtsratsvorsitzender (Chairman of the Supervisory Board), with no external institutional investors, parent company, or M&A activity disclosed.
