Chamber Furnaces with Brick Insulation or Fiber Insulation

Chamber furnaces LH 15/12 - LF 120/14 are suitable for many different glass applications. They 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 adapted optimally and individually to suit your processes.

  • Tmax 1200 °C, 1300 °C, or 1400 °C
  • Dual shell housing with rear ventilation, provides for low shell temperatures
  • 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). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
  • Motorized exhaust air flap
  • Freely adjustable air inlet integrated in furnace floor
  • Base included
  • Defined application within the constraints of the operating instructions
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
  • Controller B500 (5 prgrams with each 4 segments)
Additional Equipment
  • 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 protective or reaction gases
  • Manual or automatic gas supply system
  • Stainless steel exhaust hood as interface to customer’s exhaust system
  • Process control and documentation via VCD software package for monitoring, documentation and control
