Specification:
1. High temperature furnaces HT – T max 1820 °C
All high temperature furnaces are designed in the
most advanced technologies for universal heat treatment applications under air, protective gas atmospheres and vacuum with a high temperature accuracy. Heaters are selected in relation to working temperatures and atmospheres: Kanthal Super (MoSi2), molybdenum, tungsten or graphite. The insulation is made either of high quality ceramic fiber, graphite felt or porous alumina oxide bricks, making the HT's highly energy efficient, hence allowing fast heating cycles. Through double chamber design are fast cooling and low casing temperatures achieved. The modular design of this furnace type and the wide
range of available options enable tailor-made solutions for all applications.

2. HT Graphite/ HT Coldwall – Tm ax 2100 °C    
All HT furnaces can be made as special versions with graphite insulation and graphite heaters for temperatures up to 2100 °C in oxygen free atmospheres or vacuum. Cold wall design with molybdenum or tungsten heaters with vacuum up to 10-5 mbar.
3. HT Protective gas/HT Vacuum       
All HT furnaces can be equipped with the following
options: Gas-/vacuum tight furnace chamber, gas
feeding, post combustion devices and safety package. Standard vacuum version with rotary vane pump for a vacuum max. 10-1 mbar. Optional with a roots pump for a vacuum of 10-3 mbar.
4. HT Options:2 or 3 zone controllable, cooling trap, viewing glass, door guide rails.
