The Benchtop Hardening Furnace for Your Shop and Application
Heat treat with the inimitable Cress C181822 Furnace, with Digital LED Display Temperature Controller, amazingly accurate to within 1/4 of 1%. The Ultimate Furnace – Control Combination that ensures precisely repeatable results.
Heat treating (hardening) furnaces have higher heat output power than draw furnaces due to the elevated temperatures at which they operate. Heat transfer to the tool steel is accomplished by a very efficient process called direct radiation. Temperature uniformity in these furnaces is best in the red heat range. Normal maximum temperature is 1232°C (2250°F). Optional 1316°C (2400°F.) maximum temperature versions are available.
TEMPERATURE CONTROL: Auto tuning Microprocessor-based controller.
HEATING ELEMENTS: Alloy wire elements are coiled and mounted on the side walls in easy to change porcelain plates.
GENERAL CONSTRUCTION: The Cress benchtop heat treating furnace line comes with a case 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.
SAFETY SWITCH: These models come equipped with two door safety switches. When door is opened, elements are disconnected from power source.
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.
