ThermoLine-VAC
Vacuum and protective gas furnace

The ThermoLine-VAC series includes heating furnaces with gas-tight, double-walled, water-cooled vessels. These high-temperature furnaces are characterized by a high degree of versatility. Vacuum furnaces and process gas furnaces are among the most technically demanding industrial furnaces. Under the highest temperatures and vacuum or process gas atmospheres, debinding and sintering of ceramics as well as debinding and sintering of metals leads to very high-quality results.

Custom-made cold-wall furnace

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 reaction gas atmospheres (in particular argon (Ar), nitrogen (N2), hydrogen (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. Optionally, we manufacture our vacuum furnaces and process gas furnaces with thermal afterburning as well as with gas quenching or liquid quenching.
