Finned tubes

 

Optimized surfaces for a highly efficient heat transfer

 

Finned tubes made by Wieland Thermal Solutions are produced from plain tubes that have undergone a forming process. They serve as components in highly efficient, compact, yet extremely stable heat exchangers. Tube surfaces are optimized to the specific heat transfer requirement of the application. With a great variety of materials we ensure to use the material best suited to the specific needs, for example concerning durability and formability.

Enhanced surface tubes

Thanks to their functional surface enhancements, the outsides of the GEWA-C and Turbo-C tubes offer optimal drainage performance for condensed refrigerants. Coupled with an ideally matched inner tube surface, optimum heat transfer coefficients can be achieved. GEWA and TURBO Condenser Tubes are available with outer and inner surfaces adapted for specific needs of your application.

GEWA

  • C5 – For highest performance and efficiency
  • C+SL/LW – For weight optimized alternatives as a "drop-in" solution
  • CLF – For seawater & applications with increased fouling tendency
  • CPL – For applications with high fouling tendency


TURBO

  • C – The original condenser tube
  • CSL – Efficient and lightweight
  • CLF – For low fouling applications
  • NCT – For large capacity chillers
  • CPT – High efficiency in ferrous alloys

Optimized heat transfer for your shell-and-tube heat exchanger

The enhanced surface tubes made by Wieland Thermal Solutions have been optimized for use as condenser or evaporator tubes in shell-and-tube heat exchangers used in the refrigeration and air-conditioning industry. These can be designed to be much more compact, saving you energy, installation space and materials.

Our Materials

We offer you a broad portfolio of materials and can expand our offerings at any time to meet your specific needs regarding thermal conductivity, mechanical properties, or corrosion resistance. Enhanced surface tubes made by Wieland Thermal Solutions are already available in copper, copper-nickel, brass, carbon steel, stainless steel, and titanium.

Low-finned tubes

For extreme efficiency in a variety of applications

Low-finned tubes are a reliable solution for controlling the temperature of gases and liquids, or for evaporating and condensing refrigerants. Thanks to their larger heat transfer surface area, they offer considerable potential to save in terms of materials and fill volumes. The wide range of dimensions offered by Wieland Thermal Solutions makes these products perfect for a broad scope of applications in the refrigeration and air conditioning industry, for oil/gas coolers in machinery and plant engineering, and for intermediate vapor superheaters in process engineering.



Material designation

GEWA-K tubes offer a greater outer surface area compared to plain tubes. This is ideal for scenarios where the heat transfer surface coefficients vary significantly between the shell tube and the inner tube.

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. Low-finned tubes made by Wieland Thermal Solutions are already available in copper, copper-nickel, brass, carbon steel, stainless steel, and titanium.

Medium-high finned tubes

For compact coils and bent shapes

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.



Material designation

GEWA-D finned tubes made of copper and copper alloys are available in a wide range of sizes and withstand the highest mechanical and thermic stress. They are specially made for the individual geometries of complex heat exchangers. Copper offers the highest heat conductivity of all technical metals. It is superior in processing, hygienic and a corrosion resistant solution.

Our Materials

We offer the widest range of material in the industry and can extend it on request in case of special requirements for heat conductivity, mechanical properties or corrosion resistance. Medium-high finned tubes from Wieland Thermal Solutions are available in copper, copper-nickel, aluminium and carbon steel as well as in stainless steel in limited range.

Higher efficiency in buffer tanks

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.



Material designation

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.

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.

Safety tubes

For absolutely reliable media separation with best thermal contact

Safety tubes are used for economical and safe heat transfer. The double wall tubes feature defined leakage paths for the absolutely reliable separation of fluids. For your individual requirements concerning fluid dynamics, we decide on the most suitable surface structure. Our GEWA-safe tubes are a reliable and safe choice for applications such as the direct heating of drinking water using critical fluids as in heating technology or for controlling the temperature of sensitive chemical processes.



Material designation

For safe heating of drinking water in heat pumps, heat recovery, heat transfer units, as well as for transformer cooling.

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. GEWA-safe double wall tubes are available in copper, copper-nickel, carbon and stainless steel.
