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

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

Présentation

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.

Équipement complémentaire

• Parallel swinging door (user protected from heat radiation)
• Lift door with electro-mechanic linear drive for opening when hot
• Cooling system to cool the furnace with a defined temperature gradient or with a preset fresh air volume. Both operating modes can be switched on and off for different segments by means of the extra function of the controller.
• Protective gas connection to purge with non-flammable process gases
• Manual or automatic gas supply system
• Stainless steel exhaust hood as interface to customer’s exhaust system
• Scale to measure weight reduction during annealing
• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
• Process control and documentation via VCD software package for monitoring, documentation and control
