The claim of Grünbeck is that people all over the world have access to hygienically safe water. And by way of know-how, products and communication, Grünbeck as a water treatment specialist makes every effort to implement this basic right and to preserve it in the long term. Based on the core competence “We understand water”, Grünbeck wants to educate the public as well as water professionals and thus create WATER EXPERTS. As this is the basis for people’s conscious use of the vital resource water. An important platform in this respect is the renowned training centre “Grünbeck Forum” at the company’s headquarters in Hoechstaedt/Germany. Water specialists explain the latest news in the industry as well as innovative solutions for water treatment for the HVAC and plumbing industry, the food industry and for the generation of energy. This includes products for drinking water treatment as well as water treatment systems for heating and cooling systems or swimming pools and ultra-pure water treatment systems for hydrogen production. Furthermore, Grünbeck offers the highest level of expertise in the planning, design, manufacture and maintenance of these technical systems for water treatment.

 In 1949, Josef Grünbeck, who had been expelled from the Sudetenland, started selling products for water treatment; today, about 770 experts work for Grünbeck. As one of the most successful and respected companies for water treatment in Europe, Grünbeck inquires about, understands, and meets customer needs. The result is a continuously increasing revenue of about 150 million euros per year. Nationwide locations in Germany and a worldwide presence in all important markets ensure proximity to customers.

 2010 saw an important milestone with the foundation of the “Loni und Josef Grünbeck-Stiftung” which ensures a stable shareholder structure and thus the solid future of the company. Founded in 1949, the company is now active worldwide and has been operating as Grünbeck AG since 2024.
