LEWCO also offers a Gas-Vacuum Furnace line for smaller loads of annealing, tempering, stress relief and various other processing. This unique design uses vacuum purge to eliminate oxygen and impurities from the furnace before backfilling with nitrogen and then employing a high convection fan system for uniformity. Additional vacuum purge operations can be employed at elevated temperatures to remove product-related impurities. Hydrogen can also be added for additional brightness. These Gas vacuum furnaces can operate at temps as low as 400F and as high as 1750F. Standard sizes are 24" x 24" x 54", 36" x 36" x 60" and 60" x 60" x 104". Custom lengths are available.
