INDUSTRIAL OVENS

 

SWR05FD - Walk-In Oven 

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.

  • Cost-Effective
  • Dependable
  • Energy Efficient
  • Quality Built
  • Safe Operation
ISO 9001:2008 Registered Company

Operating Temperature

200°F (93°C) to 500°F (260°C)

 

Heating Medium

Direct fired natural gas modulating burner with direct coupled, digital actuated control valve. High turndown ratio allows for rapid heat-up and tight temperature controls.

  • Low CO and NOX emissions
  • F.M. compliant fuel train

 

Airflow PatternDual Airflow Diagram Product Page

Dual (Combination) Airflow: Hot air is supplied from both of the side walls and returned through a top plenum.

 

Input Voltage

Standard: 480/3/60. Please consult factory for additional options.

 

Control System

LEWCO’s standard control package includes a single set-point process temperature controller and redundant high-limit controller. Circulation fan(s) and exhaust 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. Other third party certifications available.

     Optional:NS Controls For Product Page

Door Switch

Disables heat when door is opened on electrically heated ovens; holds burner at low fire on fuel-fired ovens.

Batch Timer

Infinitely adjustable up to 100 hrs., includes illuminated On/ Off switch to indicate timed operation and audible alarm when time has elapsed.

Ramp/ Soak Controller

Programmable ramp/ soak temperature controller with capability to store different recipes with multiple segments.

Chart Recorder

Single pen circular paper chart recorder for continuous monitoring of temperature data. Comes with (1) Type “J” thermocouple input.

Zero Speed Switch for Fans

Minimizes nuisance tripping associated with standard air flow switch(es).

PLC

Programmable Logic Controller for processes with numerous inputs and outputs; or requiring automation of material handling equipment. The PLC can also allow for Ethernet connectivity for remote system monitoring.

Touchscreen HMI

Human Machine Interface provides the operator easy access and control of different parts of the equipment. Allows real time monitoring and provides feedback of the process in a visual, easy to read format. 

Composite Curing Controls

Data Logger: Multiple input digital data logger continuously records temperature and other process data. Allows downloading of digital data files through USB or Ethernet connection. Data can also be viewed on a full color display or on a web server when connected to a network.

Thermocouple Jacks: Thermocouple jack panel for high-temperature Type “J” thermocouples, located inside the oven. Includes wiring to data logger if purchased.

Vacuum Ports: ½” NPT thru-wall vacuum ports, each with vacuum rated manual ball valve and indicating gauge. All ports are connected to a 1” NPT header.

Vacuum Pump: Includes motor starter circuit and connection to vacuum header pipe.

Note: Sizes are approximate. LEWCO, Inc. reserves the right to change specifications without notice. 

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.

 

Doors

Heavy-duty doors on an isolated door frame minimize heat loss. Wire core gaskets create a tight seal for efficient heating. Standard doors are bi-parting swing at one end and include explosion venting latches.Door N Floor 3

     Standard Options:

  • Vertical lift guillotine door 
  • Door windows

 

Flooring

Standard ovens include a 12 gauge steel plate floor.

     Standard Options:

  • 12 gauge plate floor with (1) pair inverted angle track
  • 12 gauge plate floor with (1) pair 6” wide wheel guides
  • Insulated (100 p.s.f. max)
  • Insulated with (1) pair inverted angle track

LEWCO industrial ovens are designed and manufactured to industry standards. Our engineers regularly work to keep updated with the latest revisions in industry codes. If there is a specific industry standard or code compliance that you require for your process heating application, please contact one of our highly knowledgeable applications engineers to learn how LEWCO can help!

 

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.

  • Powered exhaust of capacity determined by burner size and solvent load present.
  • Explosion relief of adequate area determined by oven or furnace workspace volume.
