Cress Large Capacity Heat Treat Furnace

The C336 Large Capacity Furnace can be used for various types of heat treatment processes which require temperatures from 200F to 1950F. The 6 bladed axial flow fan mounted in the roof circulates the air within the chamber resulting in close gradients throughout.

FURNACE CONTROLS:

The Large Production Heat Treat Furnace come standard with a digital programmable main control and a digital high limit safety control. Solid state power switching to the heating elements, and dual door limit safety switches that interrupt power to the elements when the door is opened. All wiring is complete and ready to be connected to your power source.

HEATING ELEMENTS:

Heavy chrome-nickel wire elements are coiled and mounted in grooves in walls and door to provide all around heating, which also helps produce close gradients throughout the chamber. Solid state zero voltage switching of power to elements.

GENERAL CONSTRUCTION:

Furnace frame is constructed of heavy steel angle with 18 gauge sheet metal panels to form exterior case of the furnace. Case is finished in a pleasing gray hammertone. The vertical rising furnace door is mounted on heavy levers and is opened by lifting up on wide handle. The counterweight holds the door up in the raised position and the weight of the door gives a good brick to brick seal in the lowered position. This door protects the furnace operator from burns because the hot surface always faces away from them. The front loading furnace door opens manually very smoothly and easily.

All walls and door of these heat treat furnaces are constructed of 4 1/2″ of the finest quality insulating brick backed up by 1 1/2″ of block insulation. The roof is arched giving added strength and providing space for fan. This combination of insulation and wall thickness helps to give fast heat up and excellent heat retention for economical operation.
