Grieve's oven No. 878 is a 350°F gas-heated tunnel oven that is currently used for drying water from aluminum parts hung on a monorail pass-through conveyor. The oven's workspace dimensions measure 30 × 192 × 66 inches. The workload passes through a 24-inch-long insulated, unheated entrance vestibule, a 144-inch-long insulated heat zone with recirculated airflow and a 24-inch-long insulated, unheated exit vestibule. This oven is suspended from the factory ceiling and operated by a remote control panel.
The oven has a bottom-mounted heat chamber and a 24-inch-wide by 72-inch-high side door for access to the chamber and workspace.
This tunnel oven also features an aluminized steel interior and exterior. Interior supports are provided for the customer’s pass-through monorail, and all safety equipment required by IRI, FM and NFPA Standard 86 for gas-heated equipment are onboard this oven, including a 650 CFM, ½-HP powered forced exhauster.
