Chamber Furnaces Electrically Heated

Chamber furnace N 41/H Chamber furnace N 321 with charging stacker

Chamber furnace N 7/H

These universal chamber furnaces with radiation heating have been specifically designed to withstand heavy-duty use in the heat treatment shop. They are particularly useful for processes such as tool making or for hardening jobs, e.g. annealing, hardening and forging. With help of various accessories, these furnaces can be customized to your application requirements.

  • Compact, robust design
  • Three-sides heating: from both side walls and bottom
  • Heating elements on support tubes ensure free heat radiation and a long service life
  • Bottom heating protected by heat conducting SiC tiles
  • Stainless steel upper door jamb protects furnace structure when furnace is opened hot
  • Base frame included in the delivery, N 7/H - N 17/HR designed as table-top model
  • Exhaust opening in the side of the furnace, or on rear wall of chamber furnace in the N 31/H models and higher
  • Temperature uniformity up to +/- 10 °C according to DIN 17052-1
  • Low energy consumption due to multi-layer insulation
  • Gas spring dampers provide for easy door opening and closing
  • Heat resistant zinc paint for protection of door and door frame (for model N 81 and larger)
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
