Gas Supply System 4 for Hydrogen Applications in Tube Furnaces from Room Temperature

Gas supply system 4 allows operation with a hydrogen atmosphere starting at ambient temperature. During hydrogen operation, a pressure of approx. 30 mbar is ensured in the working tube. At the gas outlet the hydrogen is burnt off in an exhaust gas torch. Equipped with a safety PLC control system, pre-purging, hydrogen inlet, operation, fault monitoring and purging at the end of the process are carried out automatically (with at least five times the volume of the tube). If a malfunction occurs, the tube is immediately purged with nitrogen and the system is automatically switched to a safe status.

Standard Equipment

  • Available for R, RHTC, RHTH, RHTV, RSH, RSV, RSRB and RSRC tube furnaces
  • Gas panel for hydrogen and nitrogen
  • Automatic segment-related switching on/off by a magnetic valve
  • Control via safety PLC control system with touch panel
  • Exhaust gas torch with temperature monitoring
  • Over-temperature limiter with digital display as over-temperature protection for the furnace and charge
  • Excess pressure monitoring
  • Emergency purge container for nitrogen

Additional equipment

Additional Equipment

  • Additional gas panels for further non-flammable gases
  • Operation with other flammable gases
  • Gassing via program-related controllable mass flow controllers
  • Bottle pressure reducer for use with bottled gas
  • Air-water heat exchanger for closed loop water circuit (apart from RSRB and RSRC)
