This company recently built an HL7-A12 box furnace for SunCoast Automation 2000 Inc., which designs and builds automated systems for various industries. Part of the series 7000 line of box furnaces, the HL7 model has heating elements located on both side walls and reaches 2300°F.

The heavy-gauge, low-watt density coiled elements are housed in easy-to-replace holders. The 6 x 6 x 12 in. chamber is insulated with 2.5 in. low-iron insulating brick, as well as 2.5 in. of mineral wool block for energy-efficient operation and low outside shell temperature. A 1-in.-thick hearth plates provides a solid, strong work surface for parts. The double pivot horizontal swing door keeps the hot surface away from the operator at all times and is designed with a safety microswitch to shut power to the heating elements when the door is opened.

The heavy-duty hinge and cam latch ensure a positive door seal. An automated Honeywell digital time proportioning temperature controller for precision heat treating is mounted on the side wall of the unit.
