Lucifer Furnaces has shipped a seventh large dual chamber 8000 Series furnace to a U.S. auto manufacturer.
Each chamber is 24” H x 24” W x 36” L. This heavy-duty furnace-over-oven features 12-gauge sheet steel construction with reinforced members for a solid framework. The upper hardening chamber heats with 45 KW power to banks of elements on sides, door and back. The heating elements are designed with heavy gauge wire mounted in removable holders. The upper chamber cast hearth plates support the workload and can be easily replaced without disturbing the heating elements. The lower tempering oven with 20 KW power features a stainless-steel liner shielding heating elements from the workload. This liner was designed as a three-sided liner with a cast hearth plate for durability. A high cfm, 1/2 hp fan recirculates air past the elements and back through the chamber in a uniform pattern.
This unit was customized with a free-standing control panel providing the ability to separate control operation from the furnace environment. Each chamber has been outfitted with Honeywell multi-program controllers with a high limit backup controller to prevent temperature excursion events.
