Rotary tube furnace for 1300°C
Rotary tube furnaces are very versatile for continuous operation. The example in the picture shows a rotary tube furnace for a maximum temperature of 1300°C. The heated length is 750 mm. The tube diameter is 180 mm. Other tube diameters and heated lengths are also available. The rotation of the tube can be changed continuously between 1 and 30 rpm. The tube can be tilted up to 10°. The bearings system used allows precise control of the rotating tube. Above 1300°C ceramic tubes are used.

Rotary Tube Furnace for 1600 °C
This rotary tube furnace can be operated up to 1600 °C under 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 discharged continually through suitable ports. The vacuum pump supplied can be used to purge the system with inert gas before beginning operation. The ceramic tube can be tilted continuously. In order to simplify changing the ceramic tube the whole assembly including the tube suspension can be removed without dismantling the furnace itself. Tube inner diameters between 60 and 130 mm and tube total lengths from 500 to 2000 mm are available.
