Like low fin tubes, a medium high fin tube is a single integral tube - made of a singular material - but with a slightly higher fin that has a 3 mm or ⅛ inch height. Higher fin height, of course, provides more surface area and greater heat transfer capabilities.
Medium high finned tubes are primarily made of copper alloys. We extrude the fins out of the tube wall to create a slightly larger diameter than the parent tube. Because copper provides a high heat transfer in water applications, medium high fin tubes are primarily used in the refrigeration, heating and cooling industries. These tubes are commonly found in heaters, water heaters, process coolers, and heat exchangers. They are also used in oil heating and cooling applications.
The beauty of a medium high finned tube is its flexible support in bent applications. We use a proprietary set of dies in our tooling process that form a special profile to extrude the fin out of the tube. This creates a corrugated internal ridge surface that allows for tight bend radiuses - an unlimited potential for bent configurations.
Not only is the outside diameter controlled and slightly higher than the diameter of the parent tube, but fin pitch is perfect for bending - typically 11 fins per inch. Tubes can be bent after an annealed process done during manufacturing.
