Key features

High Heat Transfer Efficiency: Efficiency is about 10% higher than spiral finned tube bundles due to uniform airflow and high area expansion rate.

Extended Wear Life: Wear life is 3 to 4 times higher than other types under the same conditions due to H-shaped fin design.

Compact Space Saving Design: Larger surface area allows for smaller equipment size, reducing overall weight and suspension system load.

Low Dust Accumulation: Tandem flow characteristics minimize dust accumulation, ensuring fins are more uniformly scoured during operation.

High Fusion Rate: Fusion rate between H-shaped finned tube and steel tube is as high as 95% or more with small contact thermal resistance.

Flexible Customization: Customizable fin material (Aluminum, Steel), tube material (Carbon Steel, Stainless Steel, Copper, Alloy), and useful applications.

Wide Application Scope: Used in utility boilers, industrial boilers, marine power, economizers, and waste incinerators for coal and oil installations.

Comprehensive Quality Assurance: Includes raw material certificates, Mill Test Certificate, and 100% finished product inspection (Visual & Function).
