Lucifer Furnaces offers custom-built furnaces and ovens that comply with aerospace material specification (AMS) 2750D, which outlines requirements for meeting National Aerospace and Defense Contractors Accreditation (NADCAP) standards.
One example is a three-zone furnace the customer recently supplied to a leading aerospace manufacturer for heat-treating engine components. Measuring 20" × 20" × 20", the furnace is constructed with an angle iron steel frame and heavy-gage sheet steel facing that is welded to form a rigid unit. It is capable of heating to 2,000ºF, and cooling time is reduced via a fresh air damper system, three-zone master/slave temperature control system and over-temperature safety controls linked to a computer interface. Heavy-gage wire heating elements in removable radiant panels located in the door, side walls and rear wall generate 54 kW of power. Additionally, the horizontal swing door is secured with two cam locks and a safety micro switch to automatically switch the power off when the door is open.
