Inert-gas retort furnaces up to 1100 °C
Inert-gas retort furnaces are suitable for processes that must carried out under a defined atmosphere. The furnace range includes chamber and shaft furnaces. Retort furnaces are supplied with or without gas circulation.

Custom-designed tube furnace for environmental investigations
Horizontal tube furnace up to 1500 °C. Four separately regulated zones, sample transport unit, sample rotation, temperature measurement close to sample, different atmospheres which can be injected near the sample. The furnace itself is not gas-tight.

Special furnace for studying the dynamic corrosion of refractories by glass melts
This special furnace allows the corrosion rates of refractories in contact with highly viscous glass melts under forced convection to be investigated. The sample is immersed in the melt using a cardanic suspension device. The immersion depth can be preset precisely by means of glass level measurement.

The speed of rotation is infinitely adjustable over a wide range. Corrosive removal on the underside of the sample is measured with the aid of a precious metal tip

Combi-furnace 1700 °C/1200 °C
The picture shows a high-temperature chamber furnace for temperatures up to 1700 °C with two laterally mounted tube furnaces for temperatures up to 1200 °C. This combination of three different furnaces is used to study highly corrosive materials in the glass industry.

The bottom is moved vertically by electromechanical means and can be simultaneously rotated at predefined speeds. Samples can be moved between the chamber furnace and the two tube furnaces via an opening in the roof using a lifting and turning mechanism.

Hot bending strength (3-point) of SOFC ceramic plates Split model (SOFC: solid oxide fuel cell)
This system was designed for installation in an existing testing machine. Features: T max: 1100 °C, 200 x 100 x 200 (w x h x d) mm useable volume. Very good temperature homogeneity due to four-sided heating, despite a 100 x 100 mm window on the front side. The rear wall is designed as a door. The furnace can be split vertically into two halves which can be pulled apart. 200 x 200 mm opening in the bottom. Water-cooled steel casing.

Apparatus for determining hot bending strength (hot modulus of rupture – HMOR)
This furnace system was developed to determine the hot modulus of rupture of new refractory materials. The furnace is designed for a maximum temperature of 1600 °C. The gas-tight housing allows different gas atmospheres to be used. The oxygen partial pressure is monitored online by an oxygen sensor.

A walking beam system is installed to permit simultaneous introduction of six probes; transport is semi-automatic. Samples with a maximum size of 25 x 25 x 150 mm can be measured using the threepoint bending method. All relevant process and experimental data are recorded by the software supplied with the system and can be further processed.

MTA system (multiple thermal analysis)
This system combines several thermal analysis methods in a single unit. Samples with dimensions of up to 50x50 mm (Ø x h) can be studied at temperatures between 1300 °C and 1700 °C.

Due to the large sample size, this method is particularly suitable for heterogeneous samples. Gravimetric changes are recorded continuously as a function of temperature. The geometric changes and appearance of the sample are recorded by a CCD camera. With this newly developed method, physical chemical processes can be studied in up to five samples simultaneously.

The measurements are performed on pressed samples, which allows the
study of reactions in real pressed products. The individually recorded
data are correlated and analysed using a specially developed software
application based on LabView©.
