Armil CFS Inc. of South Holland, Ill., supplied two gas-fired box furnaces with afterburners to a California-based aerospace manufacturer. The furnaces, which are designed to operate at temperatures of 450-2200°F (232-1205°C), will be used to preheat and dewax molds used in the investment casting process. Workspace dimensions of each furnace measure 6 feet wide x 5 feet deep x 4 feet high. Operators will interface with the furnaces utilizing a PC-based industrial HMI.
