A Pit Type Tempering Furnace is a vertical industrial heat treatment furnace designed for tempering, stress relieving, aging, and other thermal processing applications involving long, heavy, or vertically oriented workpieces.

Unlike horizontal chamber furnaces, a pit type tempering furnace is installed partially or completely below floor level. Workpieces can be loaded vertically into the furnace, making this configuration particularly suitable for long shafts, rods, tubes, gears, dies, molds, pressure vessel components, and other large metal parts.
