STEBATEC guided us through the entire modernization process as a competent and reliable partner. We particularly appreciated the comprehensive support, the practical collaboration, and the quick, solution-oriented assistance—even when faced with unexpected challenges. Today, we benefit from a more efficient, safer, and more flexible facility.

For us, the key advantages were the ease of installation, the ability to provide accurate data at low flow rates, and hygienically sound measurement. The clamp-on technology can also be seamlessly integrated into existing water supply systems.

The renovation and technical upgrade of the Ländte wastewater pumping station marked a major step toward the future. The modern control system and user-friendly touch panel not only make operations more efficient but also safer. We were particularly impressed by the well-thought-out implementation of safety measures in the storm water basin area. Our collaboration with STEBATEC was constructive, reliable, and solution-oriented throughout the process.

With ARAbella, we have not only received a new control system, but also a platform that supports us throughout the entire operation. The integration of maintenance planning, documentation and process analysis not only makes our work easier, but also more efficient. We can make informed decisions because all the relevant data is available in one place.

Stebatec is very customer-oriented and takes our concerns seriously. The partially filled stationary flow measurement with the ultrasonic transit time difference measurement has proven itself. It delivers precise measured values (1-3% accuracy) and maintenance is also extremely simple thanks to the open design.

For us, the Scheidegger damper actuators is the best solution. For all our applications in the primary system with pipes up to DN 1000mm, we always have the same mechanical and electrical interfaces. The fact that even the largest dampers can be operated with a drive of only 24VDC allows us to operate our systems safely even in the event of a power failure without expensive UPS systems.
