High efficiency Ø0.32 heat exchanger
Efficient Ø0.32 grooved tube reduced pressure loss while increasing heat exchange rates to improve COP. Grooved shape is designed
to be high and slim to increase heat transfer performance inside the tube.

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.
