Evacuable protective gas retort furnaces have an indirect heating, are vacuum-sealed and purging after evacuation is not necessary. This will save time and protective gas. A clean protective gas atmosphere without the risk of explosive gas mixtures is easily adjustable. Processes can be run with low inert gas quantities. The concept of evacuable protective gas retort furnaces enables the optimization and the reproducibility of the atmospheric composition. Moreover, it is technically possible to exchange the atmosphere.

Advantages:

• uniform treatment results, even under most difficult conditions
• simple and secure control via touch screen
• proper control system “hestia”
• clean furnace atmosphere by indirect heating system and outer isolation
• service friendly
• integrable quick cooling device
