Forced Convection with bogie heart, electrically heated or gas fired

Ovens with bogie hearth from the WTR range are used to dry, temper, or vulcanize large quantities of material. The design of the oven corresponds basically to the bogie air circulation furnaces W 1000/60 A ff. They can be individually adapted to suit the required process. These ovens can also be designed for heat treatment of combustible materials according to EN 1539.

• Tmax 260 °C
• Swing door hinged on the right side
• Heating from chrome steel heating elements in the intake area of the air circulation system
• High-performance air circulation fan with vertical circulation
• Optimum temperature uniformity up to ± 4 K according to DIN 17052-1
• Oven chamber with inner shelves made of galvanized steel sheet
• Insulation structured with high-quality mineral wool
• Bogies with flanged wheels running on rails for easy and precise movement
• Over-temperature limit controller with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 - as temperature limiter controller to protect the oven and load
• Manually adjustable air inlet and exhaust air vents
• High air exchange for fast drying processes
• Oven sizes suitable for common charging systems, such as pallets, baskets, etc.

• Direct gas heating or upon request with indirect gas heating with radiation tube
• Electric chain-driven bogie in combination with rail operation for smooth movement of heavy loads up to Model W 4000
• Optimization of the temperature uniformity up +/−  3 °C according to DIN 17052-1 see page 94
• Different possibilities for an extension to a bogie hearth furnace plant:
  • Additional bogies
  • Bogie transfer system with parking rails to exchange bogies running on rails or to connect multiples furnaces
  • Motor-driven bogies and cross-traversal system
  • Fully automatic control of the bogie exchange
• Electro-hydraulic lift door
• Motorized fresh-air and exhaust air flaps, adjustable via the program
• Cooling systems for faster rapid cooling
• Bar supports with grids for higher charge weights and/or better load distribution with point leads
• Process control and documentation via VCD software package for monitoring, documentation and control
