Advanced Materials

In our business unit Advanced Materials we offer interesting solutions for many applications in powder metallurgy, technical ceramics, production of fuel cells and other innovative areas of application – as well as for ceramic 3D printing applications. The electrically heated or gas-fired furnaces can be operated in air, protective gas atmospheres or in a vacuum. Most of these furnaces can be specified for clean-room applications. Starting with small laboratory furnaces up to fully automated combi furnace systems for debinding and sintering with exhaust gas cleaning systems (catalytic/thermal), we are sure to find a solution to meet your needs. With our wide range of standard furnaces we can provide for cost efficient concepts. Due to one of the biggest engineering departments in the furnace industry, we also can quote for all kind of customized solutions!

Recommended type, for ceramic passive components

These high-quality chamber furnaces for firing, sintering and tempering have qualified themselves with the reliability for many years in daily use. Thanks to their five-side heating, the furnaces provide for a very good temperature uniformity. A wide range of additional equipment perfectly adapt these models to the process requirements.

Standard equipments

  • Tmax 1300  °C, 1340  °C or 1400  °C
  • Dual shell housing provides for low shell temperatures
  • Five-side heating provide for good temperature uniformity
  • Heating elements on support tubes provide for free heat radiation and long service life
  • Controller mounted on furnace door and removable for comfortable operation
  • Air outlet in the ceiling, motor driven exhaust air flap for models from N 440
  • Smoothly adjustable and easy-to-operate air inlet flap or sliding damper
  • Self-supporting and long-life ceiling construction, with bricks laid in arched construction
  • Protection of bottom heating and flat stacking surface provided by embedded SiC plate in the floor

Additional equipment

  • Motor driven exhaust air flap for models N 100 – N 300/..
  • Fan system for faster cooling with manual or automatic control
  • Manual or automatic gas supply systems
  • Multi-zone control for optimal temperature uniformity in the work space
  • Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load

The muffle furnaces L 1/12 – LT 40/12 are the right choice for daily laboratory use. These models stand out for their excellent workmanship, advanced and attractive design, and high level of reliability. The muffle furnaces come equipped with either a flap door or lift door at no extra charge.

Standard equipment

  • Tmax 1100 °C or 1200 °C
  • Heating from two sides by ceramic heating plates (heating from three sides for muffle furnaces L 24/11 – LT 40/12)
  • Ceramic heating plates with integral heating element which is safeguarded against fumes and splashing, and easy to replace
  • Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
  • Housing made of sheets of textured stainless steel
  • Dual shell housing for low external temperatures and high stability
  • Optional flap door (L) which can be used as work platform or lift door (LT) with hot surface facing away from the operator
  • Adjustable air inlet integrated in door (see illustration)
  • Exhaust air outlet in rear wall of furnace

Additional equipment

  • Chimney, chimney with fan or catalytic converter (not for L 1)
  • Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
