    • Oven Opening Height
      • A specialized oven opening height allows for increased process control and heat retention by setting a process specific distance between the product and the heater.
    • Belt Height
      • Belt height designed to match partner equipment and adjustability is important for designing a versatile oven solution.
    • Belt Type
      • Belt selection allows for increased process control as it can affect integrity of the part and directly affects various aspects of an oven including airflow and longevity of the belt.
    • Product Interface Device
      • HMI concept and function can be designed to match your process and production needs keeping operations and control simple and intuitive.
    • Specialized Controls and Communication
      • Customized controls allows for a higher level of process control and management. Control or monitor remotely or create a system of feedback and alarms that protect your high precision process.
    • Additional Airflow
      • Some processes require a high level of air circulation or impingement. By matching airflow to process a high level of process efficiency and quality can be achieved.
    • Eye Stop Sensors
      • Eye stops sensors on the exit end of the oven can provide multiple benefits. They can help to notify a work a part is ready, prevent parts from dropping to the floor, or trigger a robotic pick and place function.
    • Belt Fixtures
      • Our engineering team and machine shop can design custom fixtures to carry your product through the oven and simplify your procurement process.
    • Indexing Belt
      • Indexing belts provide benefit for processes requiring specialized pick up or placement of a part or can be used to control process time and match production cycles.
    • Post Cooler
      • In situations where product need to be cooled prior to handling or a next step process a filtered forced ambient air cooler can be specified to match product properties and process requirements.
    • Robotic Pick and Place Interface
      • Pick and place options range from custom fixtures to work with arm movement to a triggering mechanism letting the robot or oven know it is time to process the next part.
    • Heat Curtains
      • For many processes heat curtains provide added energy efficiency by creating a barrier at oven openings to retain as much heat as possible inside the oven chamber.
    • High/Low Temp Alarm Sensors
      • Quality assurance can be supported for temperature sensitive products by installing a temperature controller that can be set to alarm and notify workers if oven temperatures are out of a set range.
    • Infeed/Exit Feed Length Adjustment
      • Oven conveyor extensions can be customized to suit process need from as short as one foot to unlimited lengths.
    • Fume Hoods
      • Fume hoods capture fumes or volatiles and for purpose of recirculation some of the escaped heated air resulting in safer more energy efficient operation.
    • Emergency Stops
      • Protect employees and product with emergency stops. Location, look, and function can be designed to suit preferences.
    • Auto Shutdown/Start Up
      • Automatic start and stop functions can save valuable production time by having the oven warm up as employees are preparing for their shift or allowing them to work until the end of the day.
    • Digital Belt Speed Control
      • Belt speed adjustment is simple and can be programmed to suit preferences. The display can be set in feet or meters per minute or residence time inside the oven chamber.
    • Material and Product Spreaders
      • Arrangement of parts and product is important to a heating or drying process. Spreaders can ensure appropriate belt loading to maximize time and energy inside the oven chamber.
    • Lockout Controls
      • Lockout controls can be provided as needed from lockable cover over controls or special switches and power functions.
    • Belt Direction
      • Belt direction can be set to match floor layout and process needs. In the case two belts are designed they can move in the same or opposite directions.
