About STEBATEC
Founded in 1990 and headquartered in Brügg near Biel, STEBATEC AG is an owner-managed company owned by its employees and employs around 130 people. The company automates water supply systems, wastewater treatment plants, sewer networks and industrial heat generation plants. Its range of services includes process automation and general contracting, electrical planning, electrical installation, assembly as well as service, maintenance and spare parts management. In addition, STEBATEC manufactures partially filled flow measurements based on the ultrasonic transit-time difference, datalogger-based measurement campaigns with more than 50 rental measuring devices and web-based process control systems (ARAbella, AQUAbella, REbella). Further focal points are thermal oil, steam and hot water systems (temperatures from -40 to +400 °C), industrial heating systems, refrigeration systems and small hydropower plants with Pelton turbines. Around 70 % of the business is attributable to software. Customers include, among others, the city of Biel, for which more than 20 wastewater and groundwater control structures have been automated and maintained since 1995.
