Armil CFS Inc. shipped a natural-gas-fired pusher furnace to a European manufacturer of investment castings for the medical industry. The two-row, high-production furnace will be used for the burnout and preheating of investment casting molds. It has an operating temperature range of 1650-2100°F (900-1150°C). Residual wax will be consumed within the furnace chamber, eliminating the need for an afterburner. A recuperative combustion system will utilize a series of medium-velocity burners and a cross-flow recuperator operating in three zones of control. The furnace also incorporates an industrial PLC and touchscreen-based HMI.
