The unit comprises an upper chamber with operating temperatures to 2,200 degrees F and lower chamber with operating temperatures to 1,250 degrees F. Workspace dimensions are 12 by 24 by 12 in. in the upper chamber and 12 by 20 by 12 in. in the lower chamber.
Heat is provided by 40 kW installed in nickel chrome wire coils supported by ceramic plates (20 kW in each chamber). Heat-resistant alloy recirculating blowers, powered by 1/2-HP motors, provide horizontal front-to-rear airflow in each chamber.
Each furnace chamber has 6-in.-thick walls made from 2 in. of 2,300-degrees-F ceramic fiber and 4 in. of block insulation. Ceramic hearth plates support the workload in each chamber.
