High-Temperature and Atmosphere Furnaces

Kilns and Furnaces

Eisenmann has experience with all established kiln and furnace types. From the chamber kiln to the gas-tight roller-type kiln with vacuum gate, we are proficient in the entire range of kiln systems. Our engineers understand the advantages and disadvantages of the different concepts and can select the appropriate concept depending on the requirements. If required, we combine existing concepts available in our comprehensive construction kit.

Our vast experience in implementing diverse systems forms the basis of our continuous further developments:

  • Roller-type kilns
  • Tunnel kilns
  • Firing rack kilns
  • Pusher plate kilns
  • Push-through kilns
  • Mesh-belt kilns
  • Walking beam furnaces
  • Shuttle kilns
  • Lift carriage kilns
  • Lift-base kilns
  • Chamber kilns
  • and many more

If none of the systems fit your requirements, we will simply develop the appropriate technology!

As simple as possible, as complex as required!

In the past, the requirement of different atmospheres in kilns and furnaces in the successive phases of a thermal process could often only be met by discontinuous systems. The conviction that production in continuous systems is considerably more efficient and better reproducible has inspired Eisenmann to develop a gas-tight and – as required – even vacuum-tight roller-type kiln. In gas-tight or vacuum-tight roller-type kilns, e.g. when sintering powder metal components, the successive kiln zones are operated with different process gases or in a vacuum according to the process requirements. For an optimum separation of the zones from each other, the following gate systems are used as locks according to the requirements: adjustable stream barrier, stream-tight gate, gas-tight gate, vacuum-tight gate - E|GATE.

The use of the gate systems in a roller-type kiln enables an optimum separation of the atmosphere areas. The roller drive makes it possible to draw a production unit from the process zone into a lock while the feed motion continues. In this case, the atmosphere can be changed without restriction before the unit is handed over to the next process zone and is integrated into the continuous feed again.
