A 1250°F (677°C) horizontal-airflow cabinet oven, No. 1045 is currently used for heat treating at a customer’s facility. Workspace dimensions of this oven measure 38 x 38 x 38", and a 350,000 BTU/hr is installed in a modulating natural gas burner. A 2,000-cfm, 2-hp recirculating blower provides horizontal airflow. The oven includes 12" thick insulated walls composed of 2" of 2300°F ceramic blanket and 10" of 10 lb/cf density rockwool. Features include an aluminized steel exterior, 16-gauge stainless steel interior and a 325-cfm powered exhauster. Heat loss is minimized by an inner gasket that seals directly against door plug and an outer gasket that seals directly against front face of oven.
