This L Type Wound Fin Tube is made using ASTM A179 carbon steel seamless tube as the base tube and a high-purity aluminum strip (typically Al1060) as the fin. The L-type fin is tightly wound and mechanically bonded onto the base tube to maximize contact surface, promoting efficient heat transfer and corrosion resistance. It is a reliable solution for air cooler systems in industrial plants.

Tight Wound Fins: L-type fins are tightly wrapped with overlapping feet, offering enhanced heat transfer and good corrosion protection at the base.
Economical: Simple and cost-effective design for moderate operating conditions.
Improved Heat Efficiency: Enlarged surface area increases air-side heat exchange capacity.
Moderate Durability: Suitable for low to medium pressure and temperature environments.
Quick Delivery & Easy Manufacturing: Faster production times compared to embedded or extruded types.
This L Type Fin Tube is typically used in:
Air Cooled Heat Exchangers (ACHE)
HVAC Units
Gas Coolers
Oil Coolers
Process Cooling Systems
Installation Zone in Air Coolers:
Mainly used in convection zones or finned bundles where ambient or forced air flows across the fins to cool process fluid inside the tubes.
