Lucifer Furnaces Inc.
The HS series of high temperature box furnaces is designed for 2450F (1340C) operation with silicon-carbide heating elements controlled off the line by an SCR power supply. The furnace chamber is lined with lightweight ceramic fiber, providing fast heat up and quick recovery rates [heat to 2200F (1200C) in 55 min]. The fiber insulation reduces power demand to heat the chamber by 70%, which lowers overall kW requirements and utility costs. Additional features include heavy-gauge sheet steel construction, digital temperature controller, platinum/rhodium thermocouple, double-pivot horizontal swing door, and silicon-carbide hearth plate.
