Solar Manufacturing Ships Vacuum Furnace
The furnace includes an external gas-quenching system utilizing a high-capacity copper heat exchanger, 300-HP drive motor and a radial-blade fan for high-velocity gas quenching. A 35-inch Varian diffusion pump allows for high vacuum performance of 1x10-5 torr. The hot zone features a Flex Shield hot face of .040-inch-thick carbon-fiber-reinforced graphite foil and four layers of .5-inch-thick graphite-felt insulation. Thin, durable graphite heating elements are mounted cylindrically in the hot zone and are divided into multiple trim zones.
