Vacuum and protective gas furnace

The ThermoLine-VAC series includes heating furnaces with gas-tight, double-walled, water-cooled vessels. The furnace type is characterized by a high degree of versatility. Depending on customer requirements, the cold-wall furnace is designed for high vacuum (1*10-6 mbar) as well as for all common protective and reactive gas atmospheres (especially Ar, N2, H2 and mixtures thereof), reaching temperatures up to 3000 °C.  Depending on the temperature range and atmosphere, we use various heating elements made of graphite, molybdenum disilicide, tungsten or other metallic materials.
