| Advantage of High Frequency Welded(HFW) Finned Tube vs Embedded Fin (G type) & Extrude Type |
| Weldability |
High Frequency Welded (HFW) can be applied dissimilar tube and fin welds instead of G-Type and Extrude Type |
| Efficiency |
Higher heat exchange efficiency, 10% higher than G-Type, 15% higher than Extruded |
| Cost Save for Material |
Tube material cost saving, 10% for G-type (0.3mm Groove), Much less for Extruded Type |
| Flexible Fin Pitch |
Smaller and lighter equipment |
| Tube Size and Quantity |
Minimum 10% reduce tube size and quantity |
| Higher Temperature |
Applied to higher temperature depend on design temperature |
| Strong Durability & Maintenance |
Strong durability with welded fin, Easy handling and waterjet washed. |
