LEWCO Normal Duty Batch Ovens offer high quality at economical prices. The SWR series features a rear mounted heater box, which is ideal for installations with height restrictions. Heavy-duty construction and industry standard components yield durable and reliable equipment. Each unit comes complete with a one year warranty and is fully assembled, wired, and tested prior to shipment. All LEWCO ovens are manufactured to meet the requirements of NFPA 86, the national standard for industrial ovens and furnaces.
200°F (93°C) to 500°F (260°C)
Electric, low watt density Incoloy® heaters provide years of trouble free service. Standard heater bank assemblies are installed in high velocity ductwork to maximize heat transfer.
Dual (Combination) Airflow: Hot air is supplied from both of the side walls and returned through a top plenum.
LEWCO’s standard control package includes a single set-point process temperature controller and redundant high-limit controller. Circulation fan(s) include air proving circuits that are electrically interlocked with the heating circuit. All controls are housed in a NEMA 12 enclosure employing a full voltage lockable disconnect switch. Controls are wired to NFPA 70 and 79 electrical standards.

Standard oven construction includes a 16 gauge aluminized steel interior with a 18 gauge cold rolled steel exterior. Heat loss is minimized by a unique wall design featuring a welded inner shell and a completely isolated outer frame and covers.
Heavy-duty doors on an isolated door frame minimize heat loss. Wire core gaskets create a tight seal for efficient heating. Doors are bi-parting swing at one end and include explosion venting latches.
Standard ovens include a 12 gauge steel plate floor.

About NFPA 86
The National Fire Protection Association’s standard, NFPA 86, documents the guidelines for the safe operation of industrial ovens and furnaces. All LEWCO ovens are designed and manufactured to meet the requirements of this standard. Oven and furnaces in which flammable volatiles or combustible materials are present in the work space are classified by NFPA 86 as “Class A.” Similarly, ovens and furnaces in which no flammable volatiles or combustible materials are present are classified as “Class B.” Due to the risk of fire or explosion, NFPA 86 requires specific safety equipment for all Class A ovens and furnaces. Fuel gas-fired ovens and furnaces also require safety equipment.
