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
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

LH models: multi-layered insulation of light refractory bricks and special backup insulation.
