L&L Special Furnace Co. Inc. supplied an electric box furnace to a Midwestern engine manufacturer that produces parts for large industrial engines, motors and steam generators. The furnace, which has an effective work zone of 22 inches wide x 18 inches high x 22 inches deep, is used for hardening and annealing of a range of components employed in equipment manufacturing. The unit includes a complete digital control system, over-temperature protection and a counterbalanced vertical door for ease of loading.

The furnace has an alloy fan that provides excellent uniformity (±10°F) from 300°F to 1800°F. The alloy roller hearth and movable load table allow for large, heavy parts to be easily moved in and out of the furnace manually.
