It's What Makes Unifin Unique

Many of Unifin's cooling products incorporate integral finned tubing. This finned surface is formed as a thick walled aluminum tube and is put through cold rotary extrusion, forming fins that are much longer in diameter than the original tube.

This process hardens the aluminum so the fins are very strong, resulting in optimal heat transfer efficiency and exceptional durability. It can be applied to single aluminum tubes (mono aluminum) or with the addition of a liner tube within the original aluminum tube (bi-metal).

With bi-metal tubing, the fin material is always aluminum and the liner is usually copper-nickel, stainless steel or titanium, with the extrusion process creating a very strong mechanical bond between the two. The result is a rugged, reliable heat transfer surface with fins that do not break, unwind or become loose with subsequent loss of capacity.
