HIGH TEMPERATURE INDUSTRIAL BATCH FURNACES TO 1800°C (3300°F)

The CM 3300 Series furnaces are built for the industrial environment with rugged floor mount designs and heavy-duty construction. Both front loading and bottom loading configurations are offered. These furnaces utilize alumina brick and fiber insulation. Designed for strength and energy efficiency.  molydisilicide heating elements provide rapid heat and cooling rates. The furnace is designed to operate continuously at 1800°C (3300°F) in air.All CM high temperature box lined furnaces are constructed for production use. This includes heavy gauge steel for the case material and structural steel for the frame. Hot surfaces are shielded with removable panels for reasonable skin temperature while allowing quick access for maintenance purposes.

Front loading furnaces contain all controls and power components within the framework of the furnace. A separate power console is provided for the bottom loading units. Proper power control of molydisilicide elements requires a phase angle-fire SCR and step-down transformer. The standard control system includes a microprocessor based programmable controller, independent over-temperature control, transformers as required and type land – jewel thermocouples. The entire package is supplied complete and ready for immediate installation.

The 3300 Series is available in a gas-sealed configuration for applications requiring inert atmosphere control. This includes a seam-welded case with a water-cooled atmosphere seal on the door. When operating with molydisilicide elements in an inert atmosphere the maximum continuous operating temperature is limited to 1700°C (3100°F).
