Nabertherm Annealing, Hardening and Brazing Furnaces


To withstand harsh use in the laboratory, e.g. when heat-treating metals, robust insulation with light refractory bricks is necessary. The N 7/H - N 87/H models 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.


Features:

  • „„Max Temp (Tmax): 1280 °C
  • Three-sided heating from both sides and the bottom
  • Heating elements on support tubes ensure free heat radiation and a long service life
  • „„Bottom heating protected by heat-resistant SiC plate
  • „„Multi-layer insulation with high-quality lightweight refractory bricks in the furnace chamber
  • „„Exhaust opening in the side of the furnace, or on back wall of furnace in the N 31/H models and higher
  • Models N 7/H - N 17/HR are designed as tabletop models
  • Base included with model N 31/H and up
  • „„Parallel swinging door which opens downward, or upward upon request
  • „„Defined application within the constraints of the operating instructions
