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
