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.
