Fins are so designed as to create the maximum air turbulence on and around the tubes, and to increase the heat dissipation. In addition to increasing the heat dissipation, this type of construction will also add to the fuel efficiency because it permits more compact design of radiators in which the air circulation is taken to the optimum advantage.

Maximum bonding area with tubes ensures highest heat transfer capability. Primarily recommended for passenger cars, light commercial vehicles, trucks, etc. Equally satisfactory results can also be achieved by use of this design for heavy-duty applications. 

Recommended for structural stability, high endurance conditions coupled with ability to withstand the most severe operating conditions such as in desert, mining and sandy areas.
