• Robust housing design with double-walled lining and rear ventilation, exceptionally low outer-wall temperature
• Furnace door designed as hinged door, simple and easy to open
• Door lintel made of stainless steel, corrosion resistant
• Stable bogie hearth on highly rigid PU-coated steel wheels, freely movable, easily steered
• Air inlet sliding valve in bogie hearth for controlling cooling air inflow, exhaust flap in furnace roof
• Multilayer, asbestos-free insulation (lightweight refractory bricks and rear insulation), low heat loss, low energy consumption
• Heated from five sides (from both sides, rear wall, door and bottom), uniform temperature distribution in furnace chamber
• High-quality heating wire securely mounted to prevent slippage
• Heating elements wound on ceramic tubes and mounted in front of furnace wall, free heat radiation into chamber with resultant energy savings and longer service life
• Bottom heating elements in bogie hearth covered by diathermic SiC plates, high mechanical strength, protection for bottom heating

Additional equipment:

• Customised furnace sizes
• Furnaces also available with complete fibre insulation and meander-shaped heating elements for fast firing cycles
• Configuration with second door instead of rear wall and with two bogie hearths for loading batches from both sides
• Lifting doors with electrical or hydraulic drive
• Bogie hearths on rails with steel wheel for heavy loads
• Electrical bogie-hearth drive unit
• Customised transverse shunting device in front of the furnace, with parking rails
• Automatic regulation of inlet and exhaust flaps
• Cooling system with manual or automatic regulation
• Multi-zone control for optimised temperature uniformity
• Thermal or catalytic exhaust air purification systems
• Furnace furniture according to customer specifications

Furnace system for sintering ceramic fuel cells, consisting of 1 x WKF 1200/09 and 2 x WKF 2600/09

• Prepared for operation with process gas
• T max. 900 °C
• Temperature uniformity +/- 5K
• With horizontal air circulation at 900 °C, speed-controlled circulation motors
• Air duct system made of rustproof heat-resistant steel
• 3-zone regulation

Furnace systems with transverse shunting device

• While one bogie is in the furnace, two additional bogies can be loaded.
• All bogie hearths are rail-bound and can be pushed into the parking rails via the transverse shunting device either manually or by an electric drive
• 7-zone furnace regulation, excellent temperature uniformity, also in lower region
• Fan cooling with automatic exhaust flaps, faster cooling possible
• Stainless steel hood with extractor

• WK 1000/14: Bogie-hearth furnace for T max. 1400 °C, with two hydraulic lifting doors, two rail-bound bogie hearths with electrical drive and Siemens S7 controller
• Furnace complete with fibre insulation, heating elements made of meander-shaped heating bands, heating from four sides
