GEWA-H high-finned tube and GEWA-HB bi-metallic tube

High-finned tubes

For highest efficiency in controlling the temperature of gases and liquids

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.

GEWA-H high-finned tube

GEWA-H high-finned tubes

GEWA-H tubes are available in a wide variety of sizes, either in straight sections or as coiled heat exchangers. They are primarily used as heat exchangers in gas boilers and as oil and gas coolers in applications related to machinery and plant engineering.

GEWA-HB bi-metallic tube

GEWA-HB bimetallic tube

GEWA-HB tubes are high-finned tubes with a fixed inner tube made of a different material. This allows for more corrosion resistant (premium) materials to be used in combination with other, less expensive materials.

Your benefits at a glance

  • Greater surface area compared to plain smooth tubes (up to a factor of 18)
  • More compact and robust designs are possible
  • Available in straight sections or as a coiled heat exchanger
  • Also available in a bimetallic version: GEWA-HB

Our Materials

We offer you a broad portfolio of materials and can expand our offering at any time to meet your specific needs regarding thermal conductivity, mechanical properties, or corrosion resistance. High-finned GEWA-H tubes made by Wieland Thermal Solutions are already available in copper, copper-nickel and aluminum.

In the GEWA-HB tube materials like carbon steel, stainless steel, titanium or almost any other material like brass and nickel can be used for the inner tube.
