With over 100 years of combined experience, Davron designs and manufacturer’s conveyor ovens in virtually any combination of width and length. These ovens operate in a horizontal or overhead arrangement. Motion can be continuous or index from position to position in the heated chamber.
Conveyor ovens can operate at variable speeds and at temperatures up to 1,000ᴼF. Our conveyor ovens feature structural steel frames internal to the insulated walls of the oven. This construction method provides an oven of undisputed quality that is energy efficient and extremely robust.
Design and Construction Process
Each Davron conveyor oven design starts with a blank computer screen. We work with your team, learn everything we can about your application, and then our Engineering Team develops a unique concept for your system. When complete, you receive detailed mechanical and electrical AutoCAD drawings and schematics before fabrication begins.
Features can be customized depending on your needs. Conveyor ovens can be heated by various means including: gas burner systems, electric heaters, radiant panels, or infrared systems. They can utilize many types of conveying systems such as: flat-wire belts, mesh weave belts, teflon belts, plastic belts, chain-on-edge, and custom tooling. The oven arrangement can be a single horizontal pass, serpentine arrangement, or overhead arrangement with a single pass or serpentine through the oven chamber. The airflow within these conveyor ovens can be vertical in a top-down or bottom up arrangement, horizontal cross flow, or a combination of these.
Build of Materials
Each batch oven manufactured by Davron can include, but is not limited to, the following:
- Welded structural steel framework for overall support
- Heavy gauge aluminized or stainless steel interior sheeting and air distribution systems.
- Heavy gauge paint grip exterior sheeting primed and painted with high temperature oven class paint
- Our construction technique provides a finished product that can be handled as a single piece or in bolt together modules on large systems for ease of installation
- Our ovens are not constructed of “tongue and groove” panels
- Hinged access doors are provided for maintenance and cleaning access along the length of the equipment.
- A combination of accurate temperature control, temperature uniformity within the heated chamber, and conveyor speed provide the high level of control required for a successful thermal process
- Simple digital controls for basic operation or PLC controls for complex requirements. Systems can also communicate with plant networks if required
- Electrical enclosure is assembled in accordance with UL508A guidelines and has a UL508A label
- All ovens meet NFPA, OSHA, and NEC requirements
- CE certification is available if required
- Aluminized steel interiors on standard
equipment. Interiors also available in galvanized, aluminum and various
grades of stainless steel. Expansion joints formed into
the metal interior at the seams double as integral supports for the
ovens interior. These self supporting thermal expansion joints allow the
oven interior to have minimal contact to the external structure.
Minimal contact minimizes heat transfer to the exterior.
- High density insulation selected for minimal heat loss based on operating temperature.
- Structural steel main frame with welded construction.
- 16-Gauge coated steel exterior primed and painted. Also available in galvanized, stainless steel or aluminum.
- Structural steel intermediate frame
- A wide variety of belts available including steel, stainless steel, coated fabrics & plastic.
- Double insulated doors with gaskets minimize heat transfer and heat loss.
- Explosion relief door latches to meet NFPA standards.
- Heavy-Duty custom built door hinges eliminate door sag and misalignment.
- Supply plenum openings evenly distribute air toward the product and the conveyor belt system.
- High velocity airflow over high watt density
elements provide superior heat transfer. Electric elements shown. Also
available with direct or indirect fired gas heating systems.
- Return plenum openings ensure air is returned through the conveyor belt evenly across the width and length of the chamber.
- Plug style recirculation fans have higher efficiency and less heat loss than external caged style blowers.
