A large recirculating oven built by Lucifer Furnaces, Inc. in Warrington, Pennsylvania, has been shipped to a West Coast manufacturer who will be using the unit for annealing and stress relieving.
The 36" high x 36" wide x 48" deep work chamber is heated electrically with the work area baffled from the heating elements by a stainless steel liner. 50 KW are delivered through 10 gauge iron-chrome-aluminum side wall heating elements for fast heat up and load recovery rates.
A rear mounted 1 ½ HP belt driven fan directs air across the heating elements and into the work chamber in a horizontal air-flow pattern for uniform temperature.
Energy efficient 6 ½" multilayered firebrick and mineral wool block insulation minimize heat loss from the oven. A side mounted time proportioning digital temperature control unit maintains a stable environment. This unit heats to 1400°F.
