• Can be operated under standard atmosphere, controlled atmosphere or vacuum
• Extensive range of additional equipment

Split tube furnace 1200 °C, 5-zone
Split tube furnace with five separately regulated heating zones.
Split housing with half-shell modules for heating and insulation. Heated length of 1200 mm.
Separate switching unit and furnace, allowing vertical or horizontal operation.
Available with different tube diameters and heated lengths.

6-zone tube furnace for temperatures up to 1300 °C with rotating bottom
The furnace has six separate heating zones arranged asymmetrically. The useful heated region is 250 mm in diameter and 1000 mm in height. The bottom rotates with an infinitely variable speed of between 0 and 40 rpm.

Rotary tube furnace for temperatures up to 1300 °C
Rotary tube furnaces are very versatile for continuous operation. The furnace has a heated length of 750 mm. The tube diameter is 180 mm. Other tube diameters and heated lengths are also available.

The speed of rotation is infinitely variable between 1 and 30 rpm. The tilt of the tube can be infinitely varied up to 10°. A complex mounting system allows the rotating tube to be guided with precision.

4-tube furnace 1250 °C
Custom-designed tube furnace with four ceramic working tubes. The 1500 mm of heated length is subdivided into three heating zones. Each working tube has an inner diameter of 110 mm and a total length of 2500 mm. A specially designed system compensates the thermal expansion of the ceramic tubes.

5-zone tube furnace 1300 °C
Horizontal five-zone tube furnace. The heated length is subdivided into five separately regulated zones. The working tube is made of gas-tight ceramics. In combination with water-cooled stainless steel flanges, the furnace can be operated with different gas atmospheres.
