Box furnaces have a cubical shape, and therefore the material handling is easier as compared to other types of heat-treatment furnaces.

Some of the common applications of box furnaces are preheating, stress relieving, normalizing, aging, hardening and tempering. Box furnaces are useful in various industries that manufacture products such as glassware, ceramics and machine tools.

Box furnaces are mainly batch type furnaces and are available in configurations such as bench-top, cabinet, walk-in and truck-in. Another way to categorize box furnaces is their power source. A box furnace is either gas fired, electrically charged or oil-fired.

Some of the important parameters you must consider before purchasing a box furnace are:

1. Operating temperature range for the box furnace
2. Material and dimensions of the components
3. Space capacity of box furnaces
