Fin Pattern

Fin Pattern		Corrugation	Characteristics	Common Uses
Louvered			Louvered fins increase the heat-transfer capacity by creating air turbulence which reduces the boundary layer on the fin's surface, but at a cost of increased air-pressure drop across the coil.	Evaporators Heaters and Coolers Condensers operating in areas with light to normal dust conditions This fin shape is for all applications with normal dust conditions
Corrugated			Corrugated fins improve the heat transfer factor to a lower degree than louvered fins. They also have a lower resistance to air flow.	Used where icing or heavy-dust conditions are expected, like condensers for off road vehicles and for heavy dust application
Flat			Flat fins reduce ice accumulation on fins. They have the lowest resistance to air flow.	Deep freezers Cooling / freezing systems Passive air flow systems
