    Frequently Asked Questions (FAQ)

    Q: What reference voltages are available for the flange heater?
    The flange heater supports multiple reference voltages, including 220V, 380V, 400V, 480V, and 660V to accommodate different power grids and industrial requirements.
    Q: What materials are used for the heating tubes?
    The heating tubes can be customized using high-grade materials such as Stainless Steel 304, 321, 316, 310, and Titanium, ensuring durability and corrosion resistance.
    Q: What is the operating temperature range of these heaters?
    The standard operating temperature ranges from -50°C to 750°C. For applications requiring higher temperatures, pure resistance heating elements can be utilized.
    Q: How is the temperature controlled in the flange heater system?
    Temperature control is optional and utilizes control methods like contactors or thyristors, paired with precise measuring elements such as K-type thermocouples or PT100 sensors.
    Q: What testing is performed on the heaters before they are shipped?
    To ensure maximum safety and reliability, either a water pressure test or an air tightness test of the appropriate level will be conducted prior to shipment, based on the user's specific on-site requirements.
    Q: What connection and wiring methods are supported?
    Flange heaters support flange, thread/screw thread, or clamp connections. For electrical configuration, they can be wired in either Delta or Star configurations.
