Round Finned Tubes  Manufacturers, Traders, Suppliers

Round finned tubes are a type of heat exchanger component commonly used in various industrial applications where efficient heat transfer is required. These tubes consist of a base tube with external fins attached to increase the surface area available for heat exchange. The fins are typically circular in cross-section and are tightly wound around the base tube, creating a helical or spiral pattern along its length.
The design of round finned tubes allows for enhanced heat transfer efficiency by increasing the surface area available for heat exchange between the fluid flowing inside the tube and the surrounding environment. This increased surface area promotes greater heat transfer rates, making round finned tubes ideal for applications where heat dissipation or thermal regulation is critical.
Round finned tubes find extensive use in industries such as HVAC (Heating, Ventilation, and Air Conditioning), refrigeration, power generation, chemical processing, and oil and gas. They are utilized in various heat exchanger configurations, including air-cooled heat exchangers, oil coolers, condensers, and evaporators.
Overall, round finned tubes play a crucial role in improving the efficiency and performance of heat transfer systems across a wide range of industrial processes and applications.

Air Heat Exchangers of Lamellae or Finned Tube Design
Temperature exchange for gasses
With air heat exchangers, there is an exchange of temperature between a gas (normally air) and a liquid. Very often air heat exxhangers are also used as waste-gas heat exchangers or smoke-gas heat exchangers for heat recovery.
Lamellae or finned tube
In order to obtain a rather large exchange surface between air and medium (liquid) inside of the heat exchanger thin plates defined as lamellae or finned tube are applied to the pipe system. This heat exchanger type is mainly used in the processing and especially in the air conditioning technology.

Individual technical dimensioning
Each air heat exchanger is individually planned and dimensioned with modern CAD and EDP systems.
