LUCIFER FURNACES’ Model 42-B18 convection ovens have a working chamber size of 9x9x18 in. (HxWxL) and achieve heats up to 1200°F. Temperature uniformity is achieved thanks to recirculating air flow: a rear-mounted, heavy-duty fan directs air alongside wall-heating elements, then through the working zone.
Parts are protected from heating elements with a 16-gauge stainless steel liner.
Furnaces are insulated with 4.5 in. of multilayered firebrick and 2 in. of insulating cold-face block with overlapped seams for reduced thermal loss.
Onboard controls include a Honeywell UDC3500 digital time-proportioning temperature controller, with four 20-segment setpoint programs, as well as a Honeywell high-limit controller to prevent temperature excursions.
Sidewall heating element banks consist of coil-wound resistance wire in ceramic holders, making replacement easy.
The furnace shell is constructed with heavy-gauge sheet steel reinforced throughout to form a rigid freestanding floor model. A horizontal swing door with adjustable latch provides a firm, brick-to-brick seal while the safety switch powers off both fan and heating elements when the door is opened, to protect the user.
