Product Description
Low finned tubes expand the heat transfer area by adding ribs outside the tube. Compared with light tubes, they provide a larger surface area while using the same metal material, significantly improving the heat transfer coefficient.
The increased heat transfer area per unit volume reduces the number of tubes required for finned tube heat exchangers under identical heat loads, allowing for smaller shell diameters or heights and substantial space savings.
