No. 957 is used for curing potting compounds at the customer’s facility. The 300°F (149°C) electrically heated oven has workspace dimensions of 36 x 38 x 92”. Process heat is provided by the 20 KW installed in Incoloy-sheathed tubular elements. A 4200-cfm, 3-hp recirculating blower provides vertical upward airflow to the workload. The vertical conveyor oven has 4” insulated walls, top-mounted heating chamber, aluminized steel interior and exterior and air-operated lift door at the loading/unloading position. Two doors provide access to the heating chamber and floor of the workspace, and 11 workload trays, each 30 x 14”, are supported on each side by a heavy-duty roller chain driven by a 0.5-hp motor controlled by a variable-frequency drive. Controls include a digital temperature controller, manual-reset excess temperature controller with separate contactors, recirculating blower airflow safety switch and a tower light to indicate oven status. The oven is built to JIC/NEMA 12 electrical standards.
