Workspace dimensions are 72" × 156" × 96", and 360 kW installed in Incoloy-sheathed tubular heating elements provide the power, while a 24,500-cfm, 20-hp recirculating blower provides vertical downward airflow to the workload.

It also includes double doors in the front and rear, each with inner and outer door gaskets.  The inner gasket seals against the door plug, while the outer gasket seals directly against the front of the oven. A removable top-mounted heat chamber is also provided. Controls include a digital programming temperature controller, manual-reset excess temperature controller with separate contactors, recirculating blower airflow safety switch and SCR power controller.
