Cress Manufacturing offers industrial heat treating, or hardening, furnaces as well as draw furnaces, also known as annealing, tempering or forced convection furnaces.

The heat treating furnaces have higher heat output power than draw furnaces, featuring a maximum temperature of 2,250°F (1,232°C), with optional 2,400°F (1,316°C) versions also available. Efficient heat transfer to the tool steel is accomplished by a direct radiation process. Temperature uniformity in these furnaces is best in the red heat range.

Draw furnaces are used for tempering and other low-temperature processes below the red heat range where heat transfer to the tool is accomplished by the process of convection. To increase convection efficiency, these furnaces are equipped with a fan in the heating chamber to move air (forced convection). This delivers a temperature uniformity of ±10°F (±6°C) or better, with a maximum temperature of 1,250°F (677°C). Optional 2,000°F (1,093°C) versions are also available.
