No. 961 is an electrically-heated 350°F(~176.67°C) vertical conveyor oven from Grieve, currently used for preheating baskets of steel parts. 30 KW are installed in Incoloy sheathed tubular heating elements. Workspace dimensions are 30” wide x 62” deep x 118” high.
The unit has 4” insulated walls and an aluminized steel interior and exterior. It is also equipped with a removable top-mounted heat chamber (shown on floor in photo) and a motor-operated vertical lift door.
A 4200 CFM, 3-HP recirculating blower provides vertical upward airflow to the workload. Ten 200 lb. capacity carriers with roller surfaces, 31” wide x 14” long, are supported on each side by a heavy-duty roller chain. The carriers are driven through the conveyor by a 3/4-HP drive motor controlled by a variable frequency drive. Fifteen loading baskets are included with the oven. A loading table with rollers lines up with the rollers on the carriers and a latch holds the baskets in place on the carrier.
Controls onboard No. 961 include a digital temperature controller, recirculating blower airflow safety switch, 10” diameter circular chart recorder and a manual reset excess temperature controller with separate contactors.
