Solar Manufacturing shipped a vacuum furnace to Magnetic Shields Ltd., a U.K. manufacturer of magnetic shielding. The furnace, which has a hot zone measuring 36 inches wide x 36 inches high x 72 inches long, is designed for processing mu-metal shields for electronic applications and will operate in partial-pressure hydrogen or high vacuum in the 10-5 Torr range. High-vacuum performance is provided for nickel brazing of complex mu-metal assemblies.

The furnace incorporates SolarVac 5000 electronic controls with touchscreen overview programming and gives precise temperature control from ambient to 2400°F (1316°C), back down through the critical order-disorder transformation range for mu-metals and then N2 fan blower quench to ambient.
