The 300ºF, electrically-heated vertical conveyor oven by Grieve

No. 957 is a 300ºF, electrically-heated vertical conveyor oven from Grieve, currently used for curing potting compounds at the customer’s facility. Workspace dimensions of this oven measure 36” W x 38” D x 92” H.  20 KW installed in Incoloy-sheathed tubular elements heat the oven chamber, while a 4200 CFM, 3-HP recirculating blower provides vertical upward airflow to the workload.

This Grieve vertical conveyor oven features 4” insulated walls, top-mounted heating chamber, aluminized steel interior and exterior, air-operated lift door at the loading/unloading position, two access doors for the heating chamber and floor of the workspace plus eleven workload trays, each 30” wide by 14” long, supported on each side by heavy-duty roller chain driven by a ½-HP motor controlled by a variable frequency drive.   The oven is built to JIC/NEMA 12 electrical standards.

Controls on No. 957 include a digital indicating temperature controller, manual reset excess temperature controller with separate contactors, recirculating blower airflow safety switch and a tower light to indicate oven status.
