Blueing of drills in water steam atmosphere in a furnace of the NRA range

IDB Version for Debinding under Non-flammable Protective Gases or for Pyrolysis Processes

The retort furnaces of the NR and NRA product line are perfectly suited for debinding under non-flammable protective gases or for pyrolysis processes. The IDB version of the furnaces implements a safety concept by controlled purging the furnace chamber with a protective gas. Exhaust gases are burned in an exhaust torch. Both the purging and the torch function are monitored to ensure a safe operation.

  • Process control under monitored and controlled overpressure of 50 mbar relative
  • PLC controls with graphic touch panel H 1700 for data input
  • Monitored gas pre-pressure of the process gas
  • Bypass for safe flushing of furnace chamber with inert gas
  • Torch for thermal afterburning of exhaust gases
