POWER REQUIREMENTS

  • The treater power required for a specific product is a function of the material being treated, the treat level required, the area to be treated and the line speed.

    Generalization regarding treat levels and the treatability of materials is often difficult.  However, enough empirical data exists to predict with confidence the effect of a given amount of power on the more common substrates under most standard line conditions.

    Graphs follow for various materials.  Web width in inches is plotted against line speed in feet per minute.  The power required, in kilowatts, is indicated on the field of the graph. 

    The graphs have been prepared for a nominal 40-42 dyne level as is commonly specified for printing purposes.  Higher treat levels will require more power.  Consult Solo Systems for recommendations.

  • THE GENERATOR / TRANSFORMER

    The electrical power required by the corona treating process is supplied by a high frequency generator and a high voltage transformer.  Ordinary 60 cycle utility power is converted to the higher frequency and higher voltage needed to generate corona efficiently. The corona is then presented to the web by the treater station; i.e., the dielectric covered treater roll / air gap / electrode configuration.

    Full-rated generator power can be delivered to the web if the electrical components of the circuit are sized to match the generator power and frequency.  Variables are:

    1.  The effective treat area of the electrode shoe.
    2.  The dielectric constant of the electrical insulation.
    3.  The thickness of the electrical insulation.

    A number of manufacturers supply good industrial grade, solid-state electrical generators and transformers.  Sizes range from 0.5 kilowatts to 30 kilowatts.  Operating frequencies range from 8 kilohertz to 50 kilohertz.  Efficient corona treating systems are possible with most generators if careful attention is given to the electrical design details of the station and its components.
