After a vacuum is created, the fan in the heat insulation chamber generates high velocity circular air flows circulating atmospheric gases to effectively and uniformly heat the material, which results in vacuum bright tempered parts. Optimally shaped heat insulating materials are used for minimal heat loss, and more uniform temperature distribution as well as energy efficiency.

Vacuum Degassing Furnace
This furnace is used for degassing of precision, IC, gas analysis components, etc. Degassing is carried out by maintaining a virtual vacuum on atmospheric pressure of 10-5Pa for many hours. A molecular bombardment unit can be used in conjunction with this furnace to accelerate the degassing process, if necessary. To create the virtual ion, turbo, and cryo-pumps are utilized.
