Corrtherm Element Pit Furnace

The Corrtherm pit furnace offers a unique combination of high performance and low maintenance at temperatures up to 1850°F. Thick cross section, low voltage Corrtherm heating elements completely eliminate the need for a retort, even in high carbon atmospheres. The absence of a retort allows for increased part size and improved temperature uniformity. It also eliminates cracking and other maintenance problems inherent with retorts.
