    • Oven Opening Height
      • A specialized oven opening height allows for accurate heat retention and air circulation by setting a specific distance between the product and the heater.
    • Belt Height
      • Belt height can be set to match nearby equipment in order to facilitate easy loading and unloading of the product. Adjustable belt height also allows for changes in future operation.
    • Belt Type
      • Belt type selection allows for more control over air-flow, process effectiveness, and belt longevity.
    • Product Interface
      • An HMI interface is designed to match your production needs making sure that operations and control are simple and intuitive to use.
    • Specialized Controls and Communication
      • Customized controls allow for better process control and information feedback that can be wired for remote monitoring or be connected to automated systems that protect precision processes and notify you if something is awry.
    • Additional Airflow
      • Some processes require a high level of air circulation or impingement to increase efficiency and quality of the product. Airflow can also be installed to run top-down, bottom-up, or horizontally.
    • Eye Stop Sensors
      • Eye stop sensors near the exit of the oven can notify nearby employees in proximity, remotely, or notify a robot that parts are ready for pick and place actions.
    • Belt Fixtures
      • Our engineering team and machine shop custom designs special fixtures to carry your product through the oven. This can help increase even heating and part quality.
    • Indexing Belt
      • Indexing belts are key to pick and place robotic assistance by helping maintain accurate processing times and production cycles.
    • Post Process Cooler
      • When a product needs to be cooled before handling or the next step in process, ambient air coolers can be installed to maintain an accurate and steady cooling.
    • Robotic Pick and Place Interface
      • Pick and place robotics can operate with custom fixtures and timing, or specialized sensors that tell the robot when a product is ready for it’s next stage of production.
    • Heat Curtains
      • Heat curtains provide added energy efficiency by minimizing hot air loss inside the oven chamber.
    • High/Low Temp Alarm Sensors
      • Quality assurance is improved with temperature censors that notify or alarm nearby workers if oven temperatures are over or under the set acceptable range.
    • Infeed/Exit Feed Length Adjustment
      • Oven conveyor extensions can be created to suit your process’ needs. Extension lengths run from one foot to unlimited feet.
    • Fume Hoods
      • Fume hoods increase work safety and process efficiency by capturing fumes or volatiles while maintaining high levels of heat retention.
    • Emergency Stops
      • Emergency stops can be customized for appearance, location, and function to suit your needs as you protect your employees and products.
    • Automatic Shutdown/Start Up
      • Automatic start and stop functions save valuable production time by allowing ovens to warm up before a shift begins and prevents energy waste or product damage if a machine is left unattended.
    • Digital Belt Speed Control
      • Digital Belt Speed Control streamlines speed adjustment for simple non manual work. This is great for machines that will handle more than process. The display is simple and can be programmed to suit your exact preferences. It can be set in feet/meters per minute, or product time inside the oven chamber.
    • Material and Product Spreaders
      • Arrangement of parts and product is critical to the heating and drying process. Spreaders ensure that appropriate belt loading occurs to retain appropriate heat transfer and air circulation inside the oven chamber.
    • Lockout Controls
      • Assure that critical processes are protected while operations are underway with protective locking panels for switches, power, or the whole control interface.
    • Belt Direction
      • Belt direction can be set to your process needs. When the design has two belts, they can move in the same or opposite directions.
