Lucifer Furnaces says it originated the dual-chamber furnace design and perfected it with its 8000 Space Saver series. From high-temperature hardening to convection tempering, the dual-chamber design delivers a full range of heat treating capability in a rugged, compact unit that will maximize the productivity and efficiency of any toolroom.

The 8000 series features an air atmosphere high-temperature upper chamber on top of an air recirulating oven, both with easily removable coiled wire heating elements in cast holders. A manual vertical lift door for the upper chamber keeps the hot face away from the operator at all times and the lower chamber is complete with a fan assembly, consisting of a stainless steel liner with recirculating fan, to provide uniform heat at low temperatures. Both chambers have the exact same work area dimensions and each is controlled by single set point digital Honeywell controller.

With chamber sizes ranging from 6" H x 6" W x 6" L up to 24" H x 36" W x 72" L; Robert Hauser, sales manager at Lucifer Furnaces, says that the base design 8000 Space Saver furnace provides the ideal platform for customization to satisfy every customer's unique heat treating needs. The 8000 series includes models that can be used with a protective atmosphere (AM or GT Models), models that feature silicon-carbide heating elements for high temperatures up to 2750° F (EHS and HS Models) as well as lower chamber temperature ratings up to 1600° F. Lucifer Furnaces will also design chambers to meet AMS2750E specifications for temperature uniformity.
