VNKC bogie-hearth chamber furnace with forced circulation up to 650 / 850 °C

A furnace with even temperature distribution that saves on operating costs

In VNKC furnaces, the charge is loaded onto the bogie, which is then driven into the furnace. The door closing mechanism ensures excellently tight door sealing; combined with the high-quality insulation material, this brings lower furnace operating costs. The even heat distribution ensures forced internal atmosphere circulation, and you can easily control the whole heat treatment process thanks to a programmable PID controller.
