We have been pioneers in water treatment since 1947
CO2 neutral from 2025
for the next generation
We plan and design reliable water treatment units. Our ambition is to develop ever more economical and reliable processes and technologies. The focus is on membrane technology, i.e. the construction of reverse osmosis and ultrapure water units. In addition, we are also producing classic units for applications such as softening, filtration, dosing and storage.
“Water is a finite and precious resource. Acting in accordance with environmental protection measures is of central importance to us and an integral part of corporate governance. We are already thinking about tomorrow's generation today.”
