THERMCONCEPT supplies an extensive range of tube furnaces for temperatures up to 1800 °C for research and production. Tube furnaces are configured according to customer requirements and can therefore be matched precisely to the desired processes:

• For temperature ranges between 1500 °C and 1600 °C heated with SiC rods and for temperatures ranges between 1600 °C and 1800 °C with MoSi₂ heating elements
• Single- or multi-zone subdivision of the heated tube length
• Horizontal or vertical design
• Multi-tube furnaces
• Rotary tube furnaces
• Can be operated under standard atmosphere, controlled atmosphere or vacuum
• Extensive range of additional equipment

Tube furnaces 1600 °C
Tube furnaces for the production of ceramic powder under protective gas atmosphere. The working tube is closed with gas-tight, water-cooled flanges made of stainless steel. Installation with gassing station for four furnace systems.

6-tube furnace 1600 °C
High-temperature tube furnace with six ceramic working tubes. The 2000 mm of heated length is subdivided into five heating zones. The MoSi₂ heating elements are freely suspended for maximum temperature homogenity. All working tubes are fitted with gas-tight flanges made of stainless steel and are water-cooled, for purging with different gases (argon, nitrogen, hydrogen).

Vertical tube furnace for temperatures up to 1700 °C
This tube furnace contains a gas-tight working tube that is closed on one side, for experiments with a reducing atmosphere and/or corrosive components. The top of the tube is closed with a gas-tight stainless steel flange.

Adjustable horizontal tube furnace for temperatures up to 1600 °C
This furnace can be moved manually in all three directions. Each axis can be adjusted to an accuracy of 0.1 mm. The heated length of the furnace is subdivided into five separate heating zones, each with its own programmable controller.

Rotary tube furnace for 1600 °C
This rotary tube furnace can be operated at temperatures up to 1600 °C under an inert gas atmosphere. The ceramic tube has an inner diameter of 80 mm and a total length of 1600 mm. In spite of the inert gas atmosphere, the product can be introduced and removed continually through suitable ports. A vacuum pump is used to purge the entire system before operation begins, so that it is possible to change the atmosphere.

Horizontal tube furnace for temperatures up to 1800 °C
Horizontal tube furnace for T max. up to 1800 °C. The heated length is subdivided into three zones. The outer zones are regulated by coupling them to the middle zone. A closed-loop control system allows limitations on the temperature gradients in the radial direction. Gas-tight, water-cooled flanges on both ends of the working tube allow any atmosphere to be used. The working tube has a diameter of 130 mm and has special supports.

8-zone gradient tube furnace for temperatures up to 1800 °C
This horizontal gradient furnace is configured with eight zones that can be separately regulated. This means that constant temperatures and gradients can be set for different regions within the working tube.

Calibration furnace for temperatures up to 1700 °C
This furnace was designed for high-temperature calibration of thermocouples. Several thermocouples can be calibrated simultaneously. The heated length is subdivided into three separately regulated zones. All the zones are controlled by a DC power pack.
The furnace casing is water-cooled.
