Finned tubes - Import export

Heat transfer between a gaseous media and a liquid finned tube heat exchangers are often called air/water heat exchangers or gas/water heat exchangers. Heat transfer between a gas (for ex. air, steam) and a liquid (for ex. water, seawater, oil) takes place in the air-/water heat exchangers. Very often air/water heat exchangers are used as exhaust heat exchanger to gain the energy out of warm or hot exhaust fumes. Finned tube radiators can also be used as air heater, air cooler or condenser To improve the thermal output transfer from the gas to the liquid, fins made of well heat transferring materials are put on the tubes. The great increase of the thermal efficiency when applying fin tubes allows a substantial reduction in size and costs of such cooling equipment. The surface of such tubes is substantially increased and consequently less tubes are required compared with exchangers with plain tubes.

Finned tubes for efficient heat exchange Large exchange area in a small space By using finned tubes (also known as corrugated rib tubes), optimal heat exchange can be achieved in a small space. By applying so-called ribs to smooth tubes, the exchange area of ​​the tubes is increased considerably. Finned tubes are usually used where an optimal temperature exchange between gaseous media and liquids is to be achieved. Different designs for every purpose In many cases, finned tubes are built into production machines as a component in machine and apparatus construction. Finned tubes can be designed for a variety of special application conditions. The length, the design and the ribbing can be individually adapted.

We are able to manufacture fintubes pitch in the range of 3,5 - 20 mm.

Air heat exchangers as finned tube heat exchangers Heat transfer between a gaseous media and a liquid Finned tube heat exchangers are often called air/water heat exchangers or gas/water heat exchangers. Heat transfer between a gas (for ex. air) and a liquid (for ex. water) takes place in the air-/water heat exchangers. To improve the thermal output transfer from the gas to the liquid, fins made of well heat transferring materials are put on the tubes. Very often air-/water heat exchangers are used as exhaust heat exchanger to gain the energy out of warm or hot exhaust fumes. Finned tube heat exchangers can also be used as air heater, air cooler or condenser.

Recuperator systems are heat exchangers that produce hot air by utilizing the energy of high-temperature waste flue gas generated in furnace systems, boiler systems and various processes. Recuperators various heating needs of facilities such as combustion air preheating and ambient heating are met and energy consumption is minimized. Compared to economizers, they have larger surface area and dimensions at the same heat capacity. They can be manufactured as finned tube and straight tube. Recuperator heat exchangers can be made from numerous materials steel, stainless steel and other special materials.

Drycoolers are simple and reliable equipment. Their principle of operation is based on a sensible heat exchange between air and water where: air is drawn in by fans through a finned coil, while water (or a mixture of water and glycol) flows through the tubes that make up the coil and cools when ambient air (colder cooler) laps the surface of the latter. Exchange coils, with a "V" arrangement within the cooler, consisting of copper tubes and aluminum fins. The angle between the coils, the diameter of the tubes, and the thickness and length of the fins, are sized to ensure the best heat exchange performance, for a given fluid and air flow pressure drops.

The wide range of product portfolio of coils with different tube diameters, tube patterns, fin profiles, materials and options allows us to customize our coils for any specific application and fluids: air heaters, air coolers, condensers and evaporators for HVAC and various industrial applications. Kelvion heat exchanger coils are manufactured with copper tubes and aluminum or copper fins. The fins are equipped with special profiles developed at our R&D department enhancing heat transfer and keeping pressure drop at a moderate level. The customized fin spacing is achieved by collars which also provide the contact between the fin block and the tubes. Mechanical expansion of the tubes guarantees a perfect bond between the fins and the tubes leading to maximum heat transfer between both fluids.

Different applications require different designs for an optimal fit, so we provide Shell & Tube heat exchangers in single tube design with plain, low and high fin tubes and also with compact fin bundles. The plain tube design is most suitable if media have similar heat transfer properties, where the compact fin design means the best possible performance if there is a substantial difference in heat transfer rate, for example when exchanging heat between oil and water. The low and high fin single tube solution is between the previous two designs in order to further optimize on flow, pressure drop and velocities of media.
