Vacuum temper furnaces are very versatile. The design offers the heat treater a single furnace, which can perform a multitude of processes. With the use of different atmospheres, different surface finishes can be achieved. Parts requiring bright finish can be processed followed by parts requiring a drying process. With proper maintenance and bake outs, the furnace can heat treat most applications that a box furnace and a bell retort furnace can perform, combined. Cycle time reductions are achievable, compared with bell retort furnaces, and there is a significant reduction in hydrogen-based atmosphere usage.
