Infrared Systems



SAKAV has designed and manufactured tunnel ovens for all types of processing. These ovens have been designed for use with a wide range of existing conveyor systems. Since 1985 we have been providing electric gas and steam heated units with operating temperatures from 650C to 6500C.

Tunnel ovens are designed to include support points for your conveyor system. Adjustable silhouette dampers are provided on the oven end openings to minimize heat loss.

Each Oven is designed for the specific application and can include multiple heat zones and a cooling zone. Units can be provided in sections for easy installation and mating with existing conveyor system.

Our experienced engineers will work closely with you to develop a tunnel oven to readily accept your conveyor system. Every unit is completely assembled and tested prior to shipment


  • Aluminized or stainless steel interior depending on maximum temperature rating.
  • 16 gauge aluminized steel exterior with enamel finish
  • Welded structural steel, channel base provides a rigid assembly easily moved at any time.
  • Heavy duty, all welded, structural steel slide bed is supported by cross angles welded to vertical structural members to transfer load to base
  • Side hinged doors provided along oven length for access to work space and heat chamber.
  • Adjustable dampers at each end of heat zone can be positioned near load to minimize heat loss from end of oven.
  • Adjustable patented opposed louvers on full coverage supply and return ductwork.
  • Duct work removable for cleaning
  • Control Panel
  • Brushed stainless steel control panel face
  • 1 year limited warranty.


Tunnel oven width is selected to accommodate the parts and conveyor system. The speed of the conveyor system and the dwell time determine tunnel oven length.

Heat zone length is the product of the conveyor speed and dwell time. To estimate the length of tunnel over required, insert your process information in the relationship below.

To heat zone length calculated, approximately one foot must be added for insulation and silhouette dampers at each end of the oven. Equipment width will be approximately 2' wider than tunnel work space width to accommodate insulation, ductwork and control enclosure.

To receive a detailed quotation for your application complete the "Request for Quotation Data Sheet" found on the reverse side of our catalog index.

(Conveyor speed of ___ feet per hour) x (Dwell time of __ hour) = (Heat zone length of______ feet)


All Models

- 230 volts, 3-phase, 50Hz
- Other electrical characteristics available

Vertical downward air flow between full coverage ductwork above and below conveyor belt. Other air flow patterns available. Trilite Green enamel painted aluminized steel exterior.

Electric Models

Each features completely wired, side access control panel enclosing terminals for incoming power, temperature controllers, push buttons and pilot lights. Motor starter and heating element contactors electrically interlocked to shut off heaters if power to blower is interrupted and to permit operation of blower without heat for cooling. Incoloy sheathed tubular heating elements.

Gas Models

- 1,000 BTU natural gas at 6" water column pressure;
- Other gas characteristics available
Control panel as on electric models. Automatic preignition purge period and push button electric ignition contributes to ease of operation. Modulating gas burner is protected with electronic flame safety relay.
