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

(In stock)

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
  • Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
  • 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
  • Exclusive use of insulation materials without categorization according to EC Regulation No. 1272/2008 (CLP)
  • 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 programs 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
