LEWCO Inc.
INDUSTRIAL OVENS

 

CVB06FVD - Belt Conveyor Oven 

LEWCO Conveyor Ovens offer higher throughput compared to batch ovens, resulting in labor savings through increased material handling effciency. These ovens are suitable for a variety of applications such as heat-treating, curing, and drying. Belt conveyor ovens are the lowest cost and the most common type of conveyor oven. They are extremely versatile and best suited for relatively light loads. In addition to standard wire mesh belts, other special application belts are available. Each unit comes complete with a one year warranty and is fully assembled, wired, and tested prior to shipment. All LEWCO Conveyor Ovens are manufactured to meet the requirements of NFPA 86. 

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

Operating Temperature 

200°F (93°C) to 650°F (343°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 PatternVertical Down Airflow Diagram Product Page

Vertical Down Airflow: Hot air is supplied from a ceiling plenum and pulled down to a floor plenum. NOTENFPA "Class A" not available with this airflow.  

 

Input Voltage

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

 

Control System

Conveyor oven control systems include variable speed conveyor drives that can be operated in either continuous or timed index mode (0.50 - 2.00 F.P.M.).  Also 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.

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.

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. 

 

LEWCO Belt Conveyor Ovens are available in several configurations and sizes. We invite you to try our Product Configurator to get detailed information regarding workspace height, width, and length options; as well as overall length, belt width, product dwell time, air changes per minute, heat capacity and circulation fan capacity. 

 

As standard, Belt Conveyor Ovens measure approximately 30" to top of belt conveying surface and feature a 24" load/ unload zone. Workspace dimensions range from:  

  • Workspace Heights: 12" - 36" (12" increments)
  • Workspace Widths: 24" - 60" (6" increments)
  • Workspace Lengths: 96" - 360" (12" & 24" increments)

 

Standard 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. 

     Optional:

  • Side doors along oven to access workspace
  • Stainless steel construction 

 

BeltWire Mesh Belt Image

Heavy-duty 1" x 1" flat wire mesh belt; measures 3” less than workspace width. In addition to standard wire mesh belts, Teflon coated fiberglass reinforced belts are also available. These belts are non-marring and therefore well suited for handling coatings or finished product.

 

Entrance/ Exit Openings

Standard conveyor ovens are open at each end with no covers. 

     Optional:

  • Strip curtains 
  • Adjustable insulated plates
  • Pneumatic vertical lift guillotine doors 

 

LEWCO conveyor 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.
