HST Systemtechnik GmbH & Co. KG
About
Founded in 1981 and headquartered in Meschede, Germany, HST Systemtechnik employs approximately 215 people across four locations including a dedicated manufacturing facility in Ramsbeck. The company operates on a dual-pillar model combining mechanical equipment with IT automation, delivering integrated water infrastructure solutions to nearly 1,000 municipalities and over 8,000 completed projects. HST's Machines & Systems division produces hydraulic control structures including motorized weirs (ASA-Wehr, ASK-Wehr, ESK-Wehr), segment weirs, and flap gates for flow regulation. Their flushing systems span from the AWS-Spülkippe tipping bucket (volumes 200–2,600 l/m, flushing distances up to 70 m) to the AWS-3D-Strahljet for retention tank cleaning. For flow measurement and regulation, the Anaconda combines MID full-pipe flow measurement with pneumatic pinch valve control achieving over 98% accuracy, while the Alligator provides pneumatically driven regulation with no mechanical parts submerged in wastewater. The HydroKlar-SLIDE serves SBR plants with vacuumized weir plate decanting and optional turbidity-controlled withdrawal. Their IT & Automation division delivers KANiO operations management software with ISMS cybersecurity compliance for B3S and ISO 27001, SCADA V10 plant control, and SMART Machine self-diagnostic modules that pair with mechanical products for condition monitoring and self-calibration. All stainless steel production occurs at Ramsbeck under DIN 18800 Class D welding certification.
