No. 962 is a 500° F (257° C) electrically-heated, Class 100 cleanroom cabinet oven, currently used for pass-through depyrogenation of glassware. Workspace dimensions measure 24 inches wide by 36 inches deep by 27 inches high. 10KW installed in Incoloy-sheathed tubular elements provide heat, while a 600 CFM, 3/4-HP recirculating blower delivers horizontal airflow to the workload. This cleanroom oven features 4-inch insulated walls, a Type 304, 2B finish stainless steel exterior with ½ inch inside radiused corners, and interior seams that are all welded, ground, and polished. The stainless steel exterior with #4 brushed finish has continuously welded seams. The unit has single access doors, front and rear. It includes a red pilot light to indicate when the oven’s opposite side door is open, solenoid-operated door locks, and 650 CFM intake pressurizing blower. Also onboard are a 24-inch by 24-inch by 6-inch-thick HEPA fresh air filter with 2-inch prefilter, a 24-inch by 24-inch by 6-inch-thick stainless steel, high-temperature HEPA recirculating filter, and a minihelic pressure gauge and DOP validation port across each set of filters. A digital programming and recording temperature controller activates the dampers and locks the access doors during a cycle. A recirculating blower airflow safety switch turns off the blower and heat whenever a door is opened.
