Perforated L Fin - This advanced enhancement creates "tear drop" slits around the helix, effectively breaking up airflow to improve efficiency.
L-Foot Fin / Wrap-On Fin
L-Foot Tension Wound Finned Tubes also known as Wrap-On Finned Tubes, are designed for low-temperature applications, ensuring protection where tube wall temperatures remain below about 300 degrees Fahrenheit. These L-Foot tension wound finned tubes feature a fine aluminium fin strip tightly and helical wound around the tube, maximizing surface contact. An ingenious "foot" is initially formed on one side of the fin strip, imparting the name L-Foot. The strip is then expertly wound around the tube, ensuring the foot makes full contact with the tube's outer surface for optimal heat transfer. The short horizontal limb of each L ensures complete contact with the base-tube surface, maximizing thermal exchange efficiency. The tension in the fin strip during wrapping firmly seats the fin foot on the tube, securing it in position for peak performance. L-footed finned tubing is crafted to deliver exceptional heat transfer even at lower temperature ranges. The unique L-shaped design ensures the fins remain rigid and stable, effectively withstanding heat cycling and high-velocity air vibrations. This design offers a degree of atmospheric protection for the tube wall, safeguarding against corrosion. The extensive contact surface between the tube and the fin enhances heat transfer, ensuring optimal thermal performance. This fin design optimizes efficiency while remaining cost-effective, delivering high-value solutions.
The ends of the fins are securely stapled to prevent the aluminium fin from unravelling, ensuring constant contact between the fin foot and the tube for sustained performance. This element is absolutely essential for the efficient functioning of the air cooler. It acts as a conduit for heat transfer, seamlessly moving heat from the tube wall, through the fin, and into the surrounding ambient air. This process ensures optimal cooling performance.
Advantages:
Perfectly suited for low-temperature applications, catering to diverse needs with unmatched adaptability.
Among the various options available, this finning type stands out as the most cost-effective solution, offering exceptional value without compromising on performance.

The KL fin is renowned as the knurled L fin, celebrated for its enhanced bonding and performance. This finned tube mirrors the Wrap-On fin in design, crafted using a blend of Wrap-On and Embedded techniques for superior efficacy. Meticulously crafted, the fins are fashioned from strips shaped into an L configuration, then skillfully rolled into a taper that encourages curling. Subsequently, they are helically wound onto the tube in a continuous loop, maintained under tension for a secure and enduring fit. The fin embraces the tube firmly, forming a cohesive unit that enhances thermal conduction. Utilizing a spinning tool, the base tube is knurled, and the foot of the fin is expertly integrated into the knurling, resulting in a strong bond and heightened thermal performance.
With precision-engineered strips, the foot of each fin is designed to snugly abut the next, leaving no gaps and offering unparalleled corrosion protection. This strategic design not only fortifies the tube against corrosion but also ensures longevity and reliability. Similar to L fins, each end of the fin is securely attached to prevent unwinding, safeguarding the integrity of the assembly. For metal-related applications, KL-Foot tension-wound finned tubes are the go-to choice, known for their resilience and efficiency. Capable of withstanding operating temperatures up to 320°C (608°F), showcasing exceptional thermal endurance.
Advantages:
Crafted from corrosion-resistant tubes, promising longevity and unwavering performance.
Engineered to resist vibration, ensuring stability and consistent operation in dynamic environments.
Unfazed by extreme conditions, it withstands temperatures reaching 320°C (608°F) with ease.
Combining high thermal performance with unparalleled stress resistance and air corrosion protection, this product offers a truly unique advantage.
The versatile KL finned tube can seamlessly replace any existing finned tube, offering flexibility and adaptability.
LL-Foot Fin / Overlapped L
Inspired by the L-type, these fins are crafted from strips, with the foot meticulously formed into a double L shape, rolled into a taper for optimal curling. The LL-Foot Fin - Overlapped L is then expertly coiled onto the tube, ensuring a tensioned, secure fit. The fin clings to the tube with precision, one fin overlapping the foot of the next, completely enveloping the base tube for full protection. This meticulous design not only provides exceptional corrosion resistance but also enhances the longevity and efficiency of the tube. In environments where corrosion is a concern, this innovative tube design shines brightly as a cost-effective alternative to the pricier extruded type fin. Its durability and efficiency make it a preferred choice in challenging conditions.
