Electric Power Tech Korea 2025

We are proud to mark our third consecutive year at Electric Power Tech Korea (EPTK)!

As an annual fixture in our calendar, EPTK 2025 has once again proven to be the premier stage for showcasing the latest advancements in the energy sector. This year, the focus centered on the full spectrum of modern power solutions:

Power Generation & Distribution: Exploring next-gen efficiencies and grid stability.
Smart Construction: Integrating advanced engineering services into infrastructure.
EV Charging: Showcasing the future of sustainable mobility.
Railway Electrification: Advancing the tech behind modern transport systems.

After three years of participation, our commitment to bridging Korean expertise with local engineering needs is stronger than ever. Thank you to our partners and the innovators we met at the COEX center for another successful exhibition!

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.
