Professional chamber furnaces with brick insulation or fibre insulation up to 1400°C

View old post here.

The chamber furnaces LH 15/12 - LF 120/14 have been trusted for many years as professional chamber furnaces for the laboratory. These furnaces are available with either a robust insulation of light refractory bricks (LH models) or with a combination insulation of refractory bricks in the corners and low heat storage, quickly cooling fiber material (LF models). With a wide variety of optional equipment, these chamber furnaces can be optimally adapted to your processes.

• Tmax 1200 °C, 1300 °C, or 1400 °C
• Dual shell housing with rear ventilation, provides for low shell temperatures
• High furnace chamber with five-sided heating for very good temperature uniformity
• Heating elements on support tubes ensure free heat radiation and a long service life
• Controller mounted on furnace door and removable for comfortable operation
• Protection of bottom heating and flat stacking surface provided by embedded SiC plate in the floor
• LH models: multi-layered insulation of light refractory bricks and special backup insulation
• LF models: high-quality fiber insulation with corner bricks for shorter heating and cooling times. Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2.
• Door with brick-on-brick seal, hand fitted
• Short heating times due to high installed power
• Self-supporting arch for high stability and greatest possible protection against dust
• Quick lock on door
• Motor driven exhaust air flap
• Freely adjustable air inlet integrated in furnace floor
• Base included
• Defined application within the constraints of the operating instructions
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

Additional equipment

• Parallel swinging door, pivots away from operator, for opening when hot
• Lift door with electro-mechanic linear drive
• Separate wall-mounting or floor standing cabinet for switchgear
• Cooling fan for shorter cycle times
• Protective gas connection to purge with non-flammable protective or reaction gases
• Manual or automatic gas supply system
• Scale to measure weight reduction during annealing
• Process control and documentation via VCD software package or Nabertherm Control Center (NCC) for monitoring, documentation and control
