Interior of low heat storage fibre material for fast cooling times in LF models
Cooling fan connected to automatic vent flap for shorter cooling time
LH 15/12 - LF 120/14
The LH 15/12 - LF 120/14 laboratory furnaces 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 fibre material (LF models). With extensive additional
equipment these models can be optimally adapted to the intended purpose.
-
Tmax 1200 °C, 1300 °C, or 1400 °C
-
5-sided heating for very good temperature uniformity
-
Heating elements on support tubes ensure free heat radiation and a long service life
-
Protection of floor heating and flat stacking surface provided by embedded SiC plate in the floor
-
LH models: multilayered, fibre-free insulation of light refractory bricks and special backup insulation
-
LF models: high-quality fibre insulation with corner bricks for shorter heating and cooling times
-
Door with brick-on-brick seal, hand fitted
-
Short heating times due to high installed power
