    High-finned Tubes

    High-finned tubes have a much greater outer surface area than smooth tubes. This allows for particularly compact designs. Thanks to their high, thin fins, these tubes perform particularly well in the heating and cooling of liquids and gases, making them an excellent choice for applications in heating technology, as well as in machinery and plant engineering.

    Medium-high-finned Tubes

    Medium-high-finned tubes feature a significantly larger heat transfer surface area compared to plain tubes. They are ideal for compact and high-performance coils and shell-and-tube heat exchangers. Wieland medium-high-finned tubes are a proven and robust solution for water heaters, storage tanks, refrigerant condensers, oil coolers, gas coolers or safety heat exchangers and more.
