Two electrically heated, 500°F (260°C) universal ovens from Grieve are modified for simultaneous operation with reduced movement by one worker at the customer’s facility in the performance of general heat-processing operations. Workspace dimensions are 24 x 24 x 24 in (610 x 610 x 610 mm). Nichrome 5-kW wire elements heat each unit, while a 400 cfm (11,327 L/min), 0.33- hp (0.25-kW) recirculating blower provides front-to-rear universal airflow across the load in each unit. Identical controls in each oven are housed in a NEMA 12 control panel. Controls include an automatic door switch to shut off heat and the blower motor when the door is opened, digital indicating temperature controller, manual reset excess temperature controller, recirculating blower airflow safety switch, and seven-day 24-hour start-up timer.
