High Temperature Furnaces

High temperature furnaces are designed in most advanced technology for universal heat treatment applications under air, protective gas atmospheres and vacuum with a high temperature accuracy. Heaters are adapted for working at temperature and atmosphere: Kanthal-Super, molybdenum, tungsten, or graphite. Insulation is of high quality ceramic fibre, graphite felt, or porous alumina oxide brickwork. High energy saving and low heating cycles are possible. Fast cooling and low outside wall temperatures are maintained by double chamber design. The modular design of this furnace type and the wide range of available options enable tailor-made solutions for all applications.

All HT furnaces can be made as special version with graphite insulation and graphite heaters for temperatures up to 2100°C in oxygen-free atmospheres or vacuum. Coldwall design: with molydenum or tungsten heaters for vacuum up to 10-5 mbar.

All HT furnaces can be equipped with the following options: Gas-/vacuumtight furnace chamber, gas feeding-, burning-off devices and safety package. Standard vacuum version with rotary vane pump for max. 10-1 mbar. Optional with rootspump for 10-3 mbar. Useful volume 4 -500 l. Linn High Therm.
