HIGH TEMPERATURE INDUSTRIAL BATCH FURNACES TO 1600°C (2900°F)

The CM 2900 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 lightweight alumina fiber insulation for fast response times and energy efficiency. Kanthal molydisilicide heating elements provide rapid heat and cooling rates. The furnace is designed to operate continuously at 1600°C (2900°F) in air.

All CM fiber 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 temperatures 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 overtemperature control, transformers as required and type “B” thermocouples. The entire package is supplied complete and ready for immediate installation.

The 2900 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 1500°C (2730°F).
