    Product Detail

    Description

    High power capacitor made for induction heating equipment and melting furnaces.
    Water-cooled capacitors are in high demand, particularly for induction heating plants where the frequency of the current supply is above 50 cycles/second. The adoption of water-cooled capacitors will save cost for capacitor banks used for power factor correction and reduce the occupied space.
    Flair water cooled capacitors incorporate water-cooling technology that allows the capacitor to operate at great efficiency. They are dependent on the stability of the cooling water supply system. The water-cooled capacitor can be used for various heating systems such as induction heating, dielectric heating, and welding.

    Features

    • Special film dielectric designs for high efficiency induction heating applications
    • Built-in cooling water tubes for temperature control of the capacitor
    • Ultrasonic frequency design is available
    • Pressure switch design for option
    • Insulation shell or non-insulation shell are available

    Operation Conditions

    • The capacitor should be installed and operated in an environment which is free of violent mechanical vibration, harmful gases or steams, and conductive or explosive dusts.
    • The ambient temperature should range from -25℃ to +50℃.
    • The outlet cooling water should remain below 40℃.
    • The water used for cooling is a major determinant of the effectiveness of the cooling capacity. Neutral water must be used to help cool the capacitors.

    Frequently Asked Questions

    What are the primary applications for AC water-cooled capacitors?
    These high-power capacitors are specifically designed for induction heating equipment, melting furnaces, dielectric heating systems, and high-efficiency welding setups.
    Why is water cooling preferred for these capacitors?
    Water cooling helps the capacitor operate at high efficiency, particularly when current supply frequencies exceed 50 cycles/second. It reduces the occupied space and saves costs on capacitor banks used for power factor correction.
    What kinds of cooling water should be used?
    The system requires neutral water to maintain the effectiveness and stability of the cooling capacity. The temperature of the outlet cooling water should always remain below 40℃.
    What are the environmental requirements for operating these capacitors?
    They must be installed in locations free of violent mechanical vibrations, harmful gases or steam, and conductive or explosive dust. The operating ambient temperature must range between -25℃ and +50℃.
    Are there customizable configuration options available?
    Yes. Options include special film dielectric designs, built-in cooling water tubes for temperature control, ultrasonic frequency designs, optional pressure switch configurations, and a choice between insulated or non-insulated shells.
