99.95% copper for fins, special alloy brass for tubes.
Fins of wide hem with a rounded edge; thus rugged cores and additional safety to tubes.
Superior quality solder; thus a perfect joint between fins and tubes, hence efficient heat removal.
Both inside and outside solder-coating of tubes; thus better corrosion resistance.
Hydro-dynamically optimum size of tubes; thus efficient cooling over a wide temperature range.
