Catalyst test furnace up to 1000 °C with FeCrAl resistance heater
The basic principle of this furnace has been developed for research in the field of catalysts and DPF (diesel particulate filter). The multi-stage heating system combines an efficient gas pre-heater and the reaction zone in one housing. This furnace provides a lot of technical capabilities for catalysts and PDF research:
|Maximum temperature||1000 °C|
|Maximum continuous working temperature||950 °C|
|Gas temperature||850 °C|
|Gas flow||up to 100 l/min|
|Length of the working space||up to 1300 mm|
|Diameter of the working space||55 mm|
|Working position||horizontal, vertical or swivel-mounted|
|Atmosphere in the working space||ambient air; with working tube inert, oxidizing|
|Atmosphere in the heater||ambient air|
Glovebox furnace up to 2000 °C with molybdenum resistance heater
Several types of HTM’s furnace units are suitable for applications in and at glove boxes. All these furnaces have one thing in common – they require water-cooled housings in order to minimize heat emission into the glovebox.
According to your request, we can manufacture furnaces that can be operated in a glove box, flange-mounted to a glove box or operated in locks. In addition we offer sets of vacuum-tight electrical and measuring feedthroughs, customized sample supports made of alumina ceramics (e.g. plates, trays, ampoules) and gas inlet/outlets.
|Furnace type||Heating element material||Material of the heater support||Max. temperatur|
|Glovebox LOBA||FeCrAl||Al2O3 fiber concrete||1300 °C|
|Glovebox LORA||Mo||Al2O3 fiber concrete||1750 °C|
|Glovebox LORA HT||Mo||Special ceramic material (HTM)||2000 °C|
High performance gas heater for gas temperature up to 800 °C
The gas heater consists of a double-walled tube. The heating element made of FeCrAl resistance wire is fixed in the annular gap between both tube walls and heats the gas passing through the annular gap. The high electrical power (up to 6 kW) and high heat transfer (more than 70 %) can efficiently heat up gases up to a flow rate of
Based on HTM’s tube furnaces, we offer electrically heated afterburners. The exhaust gas passes through ceramic fillers, an inserted meander tube or an annular gap and is heated up to its ignition temperature.
Another variant uses a furnace with glow plug.
Crystal growing furnacewith molybdenum resistance heater up to 1750 °C
Two usual crystal growing methods determine the customized furnace design: the Tammann-Stöber method
and the Bridgeman method.
Modifications of LORA type tube furnaces with molybdenum resistance wire are used as heater.
The precise temperature control at the transition between zones and the precise and very slow motor drive control enable temperature gradients up to 12 K/mm and movement speeds of 0.1 to
