Pit Furnace

Pit furnaces are preferable when work pieces are very long and need to hang vertically to minimize distortion during heating, or for very large loads which are best handled with an overhead crane. For atmosphere processes a pit furnace configuration provides a positive seal that is critical to the success of the process.

​

HTF builds electric, retort and tube fired pit furnaces applicable for carburizing, nitriding, Ferritic Nitrocarburizing (FNC) or Gas soft Nitriding (GSN), and austenitizing, tempering, stress relief and others.

​

Our pit furnaces use heating systems that optimize operating cost and throughput.
