Corrosion Resistance: TP304L offers excellent corrosion resistance, especially in humid or slightly corrosive environments.
Lightweight, High Conductivity Fins: Aluminium fins provide superior thermal transfer while keeping the weight low.
Enhanced Heat Transfer Surface: The L-type fin design increases the external surface area for improved heat dissipation.
Cost-Effective Solution: Welded tube and wound fin design provide performance at a lower cost compared to extruded fin tubes.

Process fluid (such as oil, water, gas, or steam) flows inside the stainless steel base tubes.
Air flows across the aluminium fins on the outside of the tubes.
The fins increase the external surface area, allowing more efficient heat dissipation to the air.
The L-type fin tightly wound onto the base tube ensures good thermal contact and efficient heat transfer.
The stainless steel tube provides corrosion resistance and strength under temperature and pressure.
