Chamber Furnaces

Chamber Furnaces for Annealing, Hardening and Brazing up to 1280 °C

(In stock)

To withstand harsh use in the laboratory, e.g. when heat-treating metals, robust insulation with light refractory bricks is necessary. The chamber furnaces N 7/H – N 87/H are a perfect fit to solve this problem. The furnaces can be extended with a variety of accessories, like annealing boxes for operation under protective gas, roller guides, or a cooling station with a quench tank. Even high-performance applications like the annealing of titanium in medical applications can be implemented without the use of expensive and complicated annealing systems.

Standard Equipment

  • Tmax 1280 °C
  • Deep furnace chamber with 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-resistant SiC plate
  • Temperature uniformity up to +/− 10 °C according to DIN 17052-1
  • Low energy consumption due to multi-layer insulation
  • Base frame included in the delivery, N 7/H – N 17/HR designed as table-top model
  • Parallel guided downward swinging door (user protected from heat radiation)
  • Door movement cushioned with gas dampers/struts
  • Controller B500 (5 prgrams with each 4 segments)
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
