Chamber Furnaces


Compact Chamber Furnaces N 40 E - N 100 E



N 40 E - N 100 E

We offer compact chamber furnaces as an alternative to the pit furnaces described, which can also handle a large number of simple processes.

  •   Heating from both sides with high-quality heating elements, embedded in protective grooves
  •   Multilayered insulation with light refractory bricks in the furnace interior and special backup insulation for low power consumption
  •   Double-walled door with low exterior temperature
  •   Casing made of sheets of textured stainless steel (non-rusting design)
  •   Quiet operation of heating with solid state relays
  •   High-quality types PtRh-Pt thermocouple
  •   Freely adjustable air intake for good ventilation and short cooling times
  •   Exhaust air outlet in roof
  •   Precise temperature characteristic due to fast clocking of switching processes
  •   Standard tabletop design
  •   Stand available optionally
  •   Door contact switch for safety shutoff



  •   Models in this range include the N 40 E, N 60 LE, N 60 E and N 100 E.



  • Professional Chamber Furnaces with Brick Insulation LH or Fibre Insulation LF

    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 a wide variety of optional equipment, these models can be optimally adapted to your processes.

    •   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
    •   Side vent with bypass connection for exhaust pipe
    •   Self-supporting arch for high stability and greatest possible protection against dust
    •   Quick lock on door
    •   Freely adjustable air slide intake in furnace floor
    •   Stand included



    Additional Equipment

    •   Parallel swinging door, pivots away from operator, for opening when hot
    •   Separate wall-mounting or floor standing cabinet for switchgear
    •   Automatic vent flap
    •   Cooling fan for shorter cycle times
    •   Protective gas connector, sealed casing
    •   Manual or automatic gas supply system
