New G-fin
Highly efficient new G-fin increased heat transfer performance, reinforced corrosion resistance, and increased operating duration in
frost condition.
• Heat transfer performance improved by 13% compared to the conventional fin, even with the equivalent pressure loss.
• Epoxy acrylic coating reinforced corrosion resistance.
• 1.4 times longer heating operation in frost condition thanks to new G-fin.
