Lucifer Furnaces delivered a space-saving, dual-chamber furnace to Precision Solutions of Richmond, Utah. The company will use the furnace to heat a variety of tool steels. The unit has working dimensions of 12 inches high x 14 inches wide x 24 inches long in both the upper and lower chambers. The upper hardening chamber reaches 2200°F (1205°C), while the lower tempering oven heats to 1200°F (650°C). Both chambers are lined with a multilayered 4.5-inch combination of lightweight firebrick hot-face insulation and mineral-wool backup insulation for energy-efficient operation.

Precision Solutions, a machine shop specializing in custom tooling, is bringing their heat treating in-house with the purchase of this furnace. Both chambers contain heating elements composed of coiled heavy-gauge wire of low-watt density mounted in easy-to-replace side-wall panels. The chambers are controlled separately by Honeywell digital time-proportioning controllers. An optional over-temperature safety system is installed on the upper chamber.
