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)

• 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
