    Flange Heater Features

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

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

    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.

    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 heating capacity of a flange heater?
