Vertical Vacuum Furnace

Bottom Loading / Vertical Vacuum Furnace by Therelek

Power consumption is found to be comparatively lower in case of the vacuum furnace, than that of the salt bath furnace. The latest and advanced technology of vacuum furnace heating chamber comes from some really high-quality insulation materials and barriers, that locks the electric heating energy in the heating room itself.

Vacuum heat treatment is the combination of vacuum technology and heat treatment, where the entire heat treatment process is processed under vacuum. Currently, the working vacuum of most vacuum heat treatment furnaces is 1.33~1.33Ɨ10ˉ3Pa.
