Special furnace up to 1100 °C
Chamber furnace for testing fire protection plates and fire protection glass. Up to 1000 °C in 10 minutes. Thickness of test plates between 25 - 100 mm. Max. temperature up to 1400 °C and slight over pressure are optional available.

Chamber furnace with protective gas atmosphere up to 1700 °C
Chamber furnace with water cooled, gas tight chamber. The furnace canbe used up to 1700 °C with protective gas atmosphere. An oxygen sensor monitors the O2-content in the exhaust gas. To increase the purity of the atmosphere, a vacuum pump can be used to evacuate the chamber before starting the process.

Furnaces up to 2000 °C
For a temperature range up to 2000 °C in normal atmosphere a special furnace series has been developed. Typical areas for such furnaces are high temperature reaction studies, sintering of advanced ceramics, melting and pouring of special glasses etc.

Available as chamber-, lift-bottom or tube furnaces.

Apparatus for Hot Modulus of Rupture (HMOR) tests
This furnace system was developed to investigate the hot modulus of rupture of new refractory materials. The furance has a maximum temperature of 1600°C. The gas tight design allows different gas atmospheres to be used. The oxygen partial pressure is monitored online through an oxygen sensor.

A walking beam system is installed so that 6 samples can be introduced simultaneously. The transport of the samples is semi-automatic. 

A sample size of 25 x 25 x 150 mm can be tested according to the three-point-bending method. All relevant process and experimental data are registered by the software supplied.

Calibration furnace up to 1700 °C
The furnace shown was designed for high temperature calibration of thermocouples. Several thermocouples can be calibrated at the same time. The heating is splitted in 3 independently zones.

All 3 zones are controlled by a DC power pack, the furnace casing is water cooled.

Rotating tube furnace up to 1600 °C
This rotary tube furnaces 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 continously through sewer ports. The vacuum pump supplied can be used to evacuate the system before purging the tube with inert gas and start the process.

Multi-purpose furnace 1700 °C / 1200 °C
The photo shows a high temperature box furnace for 1700 °C. Two tube furnaces for 1200 °C are installed on one side of the box furnace. This combination of three different furnaces is used to investigate highly corrosive materials in the glass industry.

The bottom drives up and down electromechanically and can be rotated simoultaneously at predefined speeds.

Through the opening in the roof of the box furnace and by means of a lifting and turning mechanism specimens can be transferred between the three furnaces.

Special tube furnace for pyrolyses
This custom designed tube furnace for pyrolisys on a pilot scale contains 4 working tubes. The heated length of 1,5 m is devided into 3 heating zones. The furnace can be operated up to 1250 °C. Each working tube has an inner diameter of 110 mm and a total length of 2,5 m. A special system compensates the thermal expension of the ceramic tubes.
