It also is equipped with a shelf truck with shelf supports on 4" centers; stainless steel loading trays with integral holes to hold workpieces in place; and a transfer dolly with an oven-to-dolly latch to hold trays onto the supported shelves. Controls include a digital indicating temperature controller, manual reset excess temperature controller with separate contactors, and a recirculating blower airflow safety switch.
