    Flange Heater Feature

    High Surface Power

    High surface power, heating the air at 2 to 4 times the surface load.

    Compact Design

    Highly compact and compact. Due to its short, dense design, it offers excellent stability and requires no brackets for installation.

    Advanced Connection

    Combined models typically use argon arc welding to connect the heating tubes to flanges. Alternatively, a fastener assembly can be used: each heating tube is welded with a fastener. The flange cover is then secured with a nut. The tubes and fasteners are welded using argon arc welding, ensuring leak-proof sealing. Fasteners are sealed using advanced technology. Individual tube replacement is extremely convenient, significantly reducing future maintenance costs.

    Premium Quality

    Selection of high-quality imported and domestic materials. Scientific production processes and strict quality management guarantee the superior electrical performance of the heating tubes.

    Frequently Asked Questions

    What is the surface power performance of this flange heater?

    The flange heater is designed with high surface power capability, which allows it to heat the air at 2 to 4 times the standard surface load.

    Does the flange heater require brackets for installation?

    No, it does not require installation brackets. Thanks to its highly compact, short, and dense design, it provides excellent structural stability on its own.

    How are the heating tubes connected to the flanges?

    They are typically connected using argon arc welding. Alternatively, a fastener assembly can be utilized where each tube is welded with a fastener and secured to the flange cover with a nut.

    Is it easy to replace individual heating tubes during maintenance?

    Yes. When using the fastener assembly configuration, replacing individual tubes is highly convenient, which significantly minimizes future maintenance costs.

    How is leak-proof sealing guaranteed?

    The tubes and fasteners are joined using professional argon arc welding, and the fasteners are sealed using advanced technology to ensure complete leak-proof protection.

    What materials and standards are used in production?

    We select high-quality imported and domestic materials, applying scientific production processes and strict quality management to ensure superior electrical performance.
