Why use ROPEX RES Heat Seal Controls?:

    Where are Ropex RES temperature controls applied?
    They are used in:

    • Vertical and horizontal form/fill/seal bagging machines

    • Bag filling and closing machines

    • Wrapping machines

    • Bag-making machines

    • Group packaging machines

    • Special machines

     

    Why do you need Ropex RES temperature controllers?
    Because...

    • Machines are operating faster and many films are more difficult to seal

    • Consistent sealing with integrity is essential under all operating conditions

    • Machine users are demanding longer life for heatseal elements

    • Machine down time is more costly and must be avoided

    • Customers are demanding better packaging quality

    • RES temperature controllers provide reliability and functionality built upon 25 years of product development and know how.

     

    What is the functionality of the Ropex RES temperature controllers?

    Without the use of sensors, they precisely measure and regulate the temperature of the heatseal elements such as:

    • Heatseal Bands

    • Beaded Bands

    • Vertical Heatseal Tools

    • Hot Air Blowers

    • Cutting Wires

    • Contoured Bands

    • Contoured Sealing/Cutting Tools

    • Special Heat Conductors

     

    How does the Ropex RES temperature controller work?

    By the use of continuous current and voltage measurements the controller monitors the change of resistance in the heatseal element caused by the temperature variation. This measurement cycle is executed 50 times/second (50 Hz) or 60 times/second (60 Hz).

    The controller then maintains the heatseal element temperature at the pre-selected set-point by adjusting the primary voltage of the power transformer by use of "phase-control". Any change in the heatseal element temperature causes a corresponding change in its resistance. The controller recognizes the changes and instantly responds. So it is assured the actual temperature is always equal to the pre-selected set-point. Even infinitesimal thermal changes are instantly recognized and corrected with precision.

     

    The advantages of Ropex RES are:

    • The heat is produced exactly when and where it is needed.

      • Instantaneous response to thermal changes

    • Temperature measurement is accomplished directly by instantaneous electrical quality (voltage and current) with high sampling rates

      • Virtually lag free data measurement

    • The small mass of the heat seal element allows for:

      • Rapid heating

      • Rapid cooling
