HRW Automation GmbH was commissioned by CeATec to program the automation and visualization systems for the tube cooler at the Breitenfeld AG stainless steel foundry. The requirement was to cool the existing air flow of 70,000 m³/h from 480°C to 120°C.
This is achieved using 8 axial fans (8x30 kW). The fans' speed is controlled by PID controllers. The frequency converters receive their data via Profibus.
