Vestas produces its charge air coolers using a range of fin geometries.
Extremely efficient & compact so that it is perfect for use with high speed engines and other air/gas cooling environments.
7.5mm diameter tubes combined with an infinite range of fin pitches make bespoke design for each cooling requirement easily achievable. There is a range of surface options from low pressure drop plain finish to heavily corrugated surfaces designed to produce powerful turbulence and thus improve heat transfer.
Compact coolers can be manufactured from a number of material, also combined with coatings where required.
We use Ultra Compact geometry for our range of exhaust gas recovery coolers too. The same layout but with specialized materials and no fins!!
