High fin tubes is an integral extended surface tube designed primarily for applications which require high outside-to-inside surface area ratios, such as direct fired water heaters, boilers, and applications for heating or cooling gases.
High Finned Tubes - More efficiency for heating and cooling of gases, For highest efficiency in controlling the temperature of gases and liquids
High Finned Tubes
Fin-material: aluminium (some versions copper as well)
Base-tube-material: all materials (embedded types are limited)
Maximum length: up to 20 meters.
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 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 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.
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. Almost any other material of choice can be used for the inner tube in the GEWA-HB tube.
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 bi-metallic version: GEWA-HB
Medium high finned tubes provide a much larger outer surface area. This makes them ideal for use as compact and highly efficient coiled and bent elements. They offer a robust and reliable solution for everything from oil coolers to water heaters, storage units, and refrigerant condensers used in heating technology.
GEWA-D medium high finned tubes
GEWA-D medium high finned tubes are available in a number of different sizes, and they accommodate the highest of mechanical and thermal loads. A perfect match for the distinct geometries of heat exchangers.
GEWA-DS medium high finned tubes
GEWA-DS tubes are medium high finned tubes made of copper and copper alloys, as well as aluminum alloys. The inner surface texture of the GEWA-DS tube is specially developed for high-viscosity fluids
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. Medium high finned tubes are already available in copper, copper-nickel, aluminum, and steel.
Benefits at a glance:
