Solar Manufacturing received an order for a large horizontal vacuum furnace from a major high-purity metals and alloy producer serving the aerospace, aircraft and medical industries. The primary application for the furnace will be a dehydriding process. The furnace is a Model HFL-6660-EQ front-loading design with a work zone that measures 42 inches wide x 42 inches high x 60 inches deep and a gross weight capacity of 5,000 pounds. The hot zone will incorporate a combination graphite foil hot face backed by high-purity graphite felt and high-purity alumina wool for operation up to 2400oF.

The thin, curved graphite elements will provide rapid heating, and the incorporation of unique high-velocity, graphite gas nozzles surrounding the work will provide for optimum, uniform cooling of the specified load. A large vacuum pumping system with a 35-inch-high vacuum diffusion pump will allow for operation to 10-5Torr.
