Product Support

Indexing lift conveyor for loading the Barrier Oven, and a fixed indexing conveyor for the Pad Oven. Both products merge onto a transfer conveyor which delivers them to a forming press.


PLC controls with operator HMI, UL listed control enclosure


Our customer wanted to place the products on an indexing conveyor that would move the product into the heated chambers for process. On the Pad Oven the heated air is forced through the insulation pad with a vertical down airflow. The Barrier Oven has forced air from the above and below because the product is impermeable to air passing through it. The airflow design provides efficiency in regards to process time and uniformity.


The DTI-1372 design velocity accounts for the pressure drop through the product to provide an efficient process. The systems conveyors provide a stable surface to support the product and is open to allow process air to flow freely through the product, where possible. The design of the conveyors allow the customer to load and unload product easily. The conveyor belts travel approximately 8 feet in just 6 seconds to move into and out of the heated chamber quickly. The oven and transfer conveyor systems do not required any special foundations or floor pits for installation. The control system includes PLC control of the ramp and soak temperature profiles and starting sequence for all components and flame safety systems. All functions are controlled from the operator HMI (touch screen) and multiple recipes can be stored for future use for various product requirements. The entire system is fully assembled and factory tested for operational verification prior to shipment.    


Davron Technologies, Inc. designs and manufactures ovens of this type to meet many unique process requirements, including but not limited to, the following:

  • Airflow: Designs can be completed to provide airflow from any direction within the heated chamber as required by the product. This particular process is vertical up and down airflow but it can be horizontal from either side.
  • Industries Served: Automotive, Insulate and Acoustic Barrier Manufacturing/Regeneration, or any industry that requires batch processing.
  • Materials Processed: Particularly any Automotive Carpet or Insulating Pad Product, Petroleum Based Acoustic Barrier with a directional flow requirement. The oven /conveyor system can also be used for many other types of products and can be designed in any size required.
  • Other Processes: Preheating, Curing, Drying, Solvent Drying, Bonding
  • Heating Systems: Modulating Gas Fired Direct or Indirect, Electric, or Thermal Oil.

Davron exists to be the industry leader in non-standard products engineered to meet the customer's need and unique process.
