Bench Top Tempering Furnaces – Cress

“Draw Furnaces” also known as annealing, tempering or forced
Draw furnaces are used for tempering and other low temperature processes. They normally operate at temperatures below red heat range where heat transfer to the tool steel is accomplished by the process of convection heat transfer. 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 ± 6°C (± 10°F) or better. Maximum temperature is 677°C (1250°F.). Optional 1093°C (2000°F.) maximum temperature versions are available
Draw Units: These models are equipped with a stainless steel fan and motor for forced convection temperature uniformity.

Uses: These furnaces are designed for general use in the shop, laboratory or factory where temperatures from 300-1250°F. ±10°F are required. They are used for such purposes as tempering, annealing and stress relieving. 2000°F maximum temperature option is available for all models at additional cost.

Temperature Controls: Auto tuning microprocessor-based controller and solid state relays for precise temperature control.

Heating Elements: Alloy wire elements are coiled and mounted on the side walls in easy to change porcelain plates.

General Construction: The furnace case is constructed of heavy gauge sheet steel and finished in gray hammertone. The walls and door are constructed of the finest quality insulating fire brick backed up by 1800° F block insulation. Comes complete with cord and plug.

Safety Switch: These models come equipped with dual safety switches. When the door is opened, power is disconnected from the heating elements and fan motor.

Door: The counter balanced easy to operate door, opens up and away from the furnace, keeping the hot side away from the operator.

A kaowool® Rope seal is installed on the door where it meets the chamber.
