Chamber Furnaces with Brick Insulation or Fiber Insulation

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
