Air cooled heat exchangers

Alfa Laval HyperFin – Slitted fin design maximizes heat transfer

Alfa Laval’s HyperFin slitted tube fins increase heat transfer compared to standard API 661 type fins, resulting in reduced size and cost of the cooling system.

The slits on the aluminium fins interrupt the air flowing over the fin surfaces. This prevents the forming of a stagnant layer of air on the fin surfaces, and thereby increases heat transfer. The impact on the pressure drop and required fan horsepower is minimal, keeping operating costs low.
