VAC AERO International will supply two vacuum furnaces to a New Hampshire-based castings manufacturer. A horizontal vacuum furnace with work-zone dimensions measuring 36 inches wide x 36 inches high x 50 inches deep is the first VAC AERO furnace to be installed at this facility and will replace an old existing furnace. The hot zone is comprised of curved graphite elements, and the heavy-duty hearth is constructed with quickly removable rails of pure molybdenum to support a uniformly distributed load of 3,000 pounds at 2400°F. The lightweight design’s low thermal mass enables faster quenching and longer life.

The furnace is equipped with an external recirculating inert-gas quenching system and includes gas storage and dual-loop cooling systems. The operating system is based on VAC AERO's versatile HC900 interactive hybrid-control package with SCADA and complete network-integration capabilities as well as remote monitoring and control.
