The product to be heated passes through No. 878's 24" long, insulated, unheated entrance vestibule; a 144" insulated heat zone with recirculated airflow; and a 24" insulated, unheated exit vestibule. The gas-heated tunnel oven is suspended from the factory ceiling and operated by a remote control panel. While 500,000 BTU/hr is installed in a modulating natural gas burner to heat the workspace, a 6,000 cfm, 5 hp recirculating blower provides vertical downward airflow to the workload. The unit has a bottom-mounted heat chamber and a 24 x 72" side door for access to the chamber and workspace.
