Fin spacing

Fin spacing is the distance between fins which are used on fan coils, air coolers, dry coolers, evaporators and condensers. Increasing or decreasing fin spacing has a major impact on the coil performance.

Fin spacing is the distance between fins which are used on air coolers, dry coolers, evaporators and condensers. Decreasing the spacing between fins increases efficiency and it is an inexpensive solution. Therefore, the optimum solution is to have as little spacing as possible. A fin spacing of 1.5-5.0 mm is used for dry air cooling. A fin spacing of 3-7 mm is used for humid air where there is a risk of condensation. A fin spacing of 6-20 mm is used in freezer room conditions.
