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

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
• Stainless steel upper door jamb protects furnace structure when furnace is opened hot
• 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
• Exhaust opening in the side of the furnace, or on rear wall of chamber furnace in the N 31/H models and higher
• Parallel guided downward swinging door (user protected from heat radiation)
• Door movement cushioned with gas dampers/struts
• Controller with touch operation 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
