For the annealing of frameworks made of cobalt-chromium after laser sintering the chamber furnaces N 7/H - N 41/H are used. These furnaces will be equipped with a gax-box as well as an automatic gas-supply system for one non-flammable protective gas, e.g. Argon. Please ask for our catalog “Thermal Process Technology”.

• Tmax 1150 °C
• The recommended working temperature is max. 1100 °C. Higher wear and tear of the gassing box has to be expected at higher working temperatures up to 1150 °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 chamber furnace in the N 41/H models and higher
• Chamber furnaces N 7/H - N 17/HR are designed as tabletop models
• Base included with chamber furnace N 41/H
• Protective gas boxes for inert gas atmosphere with additional thermocouple, type K
• Solenoid valve, controlled via the extra function of the controller B400
• Digital temperature indicator for measuring the temperature inside the gassing box
• Charging plate and annealing and hardening foils
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
