Chamber Furnaces with Brick Insulation or Fiber Insulation up to 1400 °C

These big 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.

Standard Equipment · Tmax 1200 °C, 1300 °C, or 1400 °C · 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 · Door with brick-on-brick seal, hand fitted · Gegenerously dimensioned heating provides for short heating times · Self-supporting arch for high stability and greatest possible protection against dust · Motorized exhaust air flaps · Freely adjustable air inlet integrated in furnace floor · Base included · Controller B500 (5 prgrams with each 4 segments),

Additional Equipment · Parallel swinging door for opening when hot with hot surface facing away from the operator · Lift door with electro-mechanic linear drive · Separate wall-mounting or floor standing cabinet for switchgear · Cooling system to cool the furnace with a defined temperature gradient or with a preset fresh air volume. Both operating modes can be switched on and off for different segments by means of the extra function of the controller. · 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.
