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.

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.

Your advantages at a glance

• Proven solution in a wide range of applications
• Increased heat transfer surface compared to plain tubes
• Material savings due to reduced tube length
• Filling quantity reduction due to higher efficiency

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.

Your advantages at a glance   

• High surface enlargement compared to plain tubes
• Ideal for compact and robust heat exchangers
• Excellent bending properties and processability
• Availability of various dimensions, internal structures and materials

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.

Your advantages at a glance

• Highest surface enlargement compared to plain tubes (up to factor 18)
• Enables particularly compact and robust designs
• Available in straight lengths or as coiled heat exchanger
• Also available as bimetallic version GEWA-HB

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.

GEWA-safe tubes are available in copper and copper alloys and provide safe drinking water heating in heat pumps, heat recovery systems, heat transfer stations and are used for transformer cooling.

Your advantages at a glance

• Reliable | Trust in reliable media separation through the double-tube system with defined leakage spaces.
• Efficient | Use direct and safe heat transfer of the media involved.
• Highest system availability | Detect leaks at an early stage and eliminate them during scheduled maintenance.
• Compact and economical | Reduce material costs and equipment requirements.
