An electrically heated oven will be used for drying small parts in a tray at a manufacturing facility. The 250°F (121°C) oven, designed and built by Grieve, has 3 kW installed in Incoloy-sheathed tubular heating elements. A 300-CFM, 1/3-hp recirculating blower provides vertical airflow upward through tray to the workload.
The oven holds one stainless steel tray 6" wide by 18" long by 6" deep with a perforated bottom. The tray sets on a drip trap/air diffuser, which is removable for cleaning. Controls include a digital indicating temperature controller, manual reset excess temperature controller with separate contactors and a recirculating blower airflow safety switch.
