Series 8000 LI - Fiber Lined Dual Chamber Furnaces

Unique “Space Saver” design offers convenience and economy of two independently controlled chambers in one packaged assembly. The upper chamber (Hardening) is designed with lightweight ceramic fiber insulation for energy saving low power input and maximum heating efficiency for operation to 2200°F. The coil wound heating elements are fully supported on ceramic rods for rapid radiation with faster heat up rates. This unique design provides easy element access and low cost, individual replacement of the wires. The lower chamber (Tempering) is complete with a stainless steel liner and fan to recirculate the heat for uniform temperature. Available at operating temperatures of 800°F (88), 1200°F (82), 1400°F (84), and 1600°F (86). Ideal for Tool Rooms and Schools, providing a complete heat treat station in one furnace.

Ruggedly constructed and rated for work loads up to 40 lbs. per square foot of hearth area. All models are completely wired, assembled, test fired and shipped ready for connection to main power supply. Compact design, fast installation, and simple, safe, dependable operation.

Standard Features

  • Welded sheet metal single shell construction.
  • Both chambers designed with same working dimensions.
  • Heavy gauge coil wound low watt density heating elements for longer life.
  • Multi-layered energy efficient lightweight ceramic fiber insulation in upper chamber and firebrick in lower oven for maximum heat storage and minimum heat loss.
