VERTICAL CONVEYOR OVEN FROM GRIEVE

April 24, 2012

No. 959 is a 300°F (148.8°C), electrically-heated, vertical conveyor oven from Grieve, currently used for curing electronic components. Workspace dimensions on this oven measure 36″ wide x 89″ deep x 115″ high. 40 KW are installed in Incoloy sheathed tubular heating elements to heat the oven chamber, while a 6000 CFM, 5 HP recirculating blower provides vertical downward airflow to the workload.

This Grieve vertical conveyor oven features 4″ insulated walls, aluminized steel interior and exterior, motor-operated vertical lift door at the loading/unloading opening and two (2) independent doors for access to the workspace. Twenty-seven (27) product carrier trays, each 30″ wide by 14″ long, are supported at each side by heavy-duty roller chain, driven by a 1/2-HP drive motor that is controlled by a variable frequency drive.

Controls on No. 959 include a digital temperature controller, manual reset excess temperature controller with separate contactors, and recirculating blower airflow safety switch. A tower light indicates machine status. The oven is built to exacting JIC/NEMA 12 electrical standards.
