Lucifer Furnaces recently delivered a large fiber lined forced air recirculating oven to The Lincoln Electric Company in Cleveland, Ohio. With chamber dimensions of 24”H x 24”W x 36”L, the oven features a uniformity of +/-15°F between 200°F and 1200°F. Constructed with ceramic fiber insulation for energy savings and faster heating and cooling cycles, the oven includes a stainless steel roller hearth for ease of loading/unloading. Heating elements located on the side walls are designed from heavy gauge resistive element wire mounted over ceramic tubes for full radiation from the coils for rapid heat. Each element is mounted individually for easy low cost replacement. A high volume stainless steel fan assembly with heat slinger circulates air around the alloy liner, past the heating elements, and through the chamber providing uniform heat to the workload. This oven includes a Honeywell over temperature controller and chart recorder. A safety micro switch automatically shuts off power to the fan and heating elements when the door is opened.
