Wisconsin Oven Corporation designs and manufactures electrically heated and gas fired pit furnaces. A pit furnace is ideal for solution treatment, tempering and the heating of any densely packed load carried in a cylindrical basket. We offer pit furnace designs for basket diameters to 48" and maximum temperature ratings to 1,400°F.
Wisconsin Oven’s pit furnace is manufactured with 6” insulation sandwiched between a heavy gauge stainless steel liner (stainless steel at 1,250°F and above) and a heavy gauge plate steel exterior. Our pit furnaces utilize high pressure recirculation blowers to force heated air through the load in a vertical, top-down arrangement. This arrangement provides much faster heating than most other conventional furnace designs.
The pit furnace design saves on valuable floor space in comparison to horizontally loaded equipment, which requires space for the swing of the doors and for loading/unloading. It also provides easy loading because the door lifts up and swings completely away from the loading area to avoid damage. Doors are available in either manual or air-operated designs.
