Fin-tube heat exchanger - Import export

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.

Customized air-water heat exchangers for industrial use Three types of air-water heat exchangers Three different designs o air-water heat exchangers The Anthermo GmbH delivers three different designs of air-water heat exchangers: Finned tube heat exchangers Lamella heat exchangers Straight tube heat exchangers These heat exchangers are designed in a way, that inside the tube water or another liquid circulates. The air flows around outside the tubes or the fins/lamellas. The connection between the fins and the tube is used to enlarge the space for heat transfer between the liquid and the gas fluid. The technical figures (for ex. amount of air, temperature, pressure, waste of air) can be different for the air-water heat exchanger. Also the operating conditions and the environment conditions can vary from application to application.

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.

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.

The condensers, available in stainless steel/aluminium, are suitable for refrigerants (Frigene) and ammonia (NH3), depending on application.

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 design and manufacture products based on the project sent by our customers or according to customer requirements. Calculations, designs and projections according to customer demand and in accordance with ASME Code Section VIII Div 1 and 2 (American Society Mechanical Engineers), API 661, API 650 (American Petroleum Institute), TEMA (Tubular Exchanger Manufacturers Association), AD-MERKBLAATTER, CODAT, DIN, EN 13445, PED 2014/68 / AB and TSE. The most common processes in the Oil & Gas, Petrochemical & Chemical, Food & Beverages and Heavy & Light Industry require a significant number of equipment to exchange heat or to storage different fluids or components. The fluid can be either liquid or gas, and one of each flows into the tube and the other flow out of the tube is used to boil, condense or cooling the fluid.

Tubes wound into a spiral shape Coaxial heat exchangers consist of two or more pipe coils, which are routed into one another and wound up in a spiral shape. The primary medium runs in countercurrent to the secondary medium. Fast temperature exchange This countercurrent design achieves a very rapid temperature transition with high efficiency between the liquids. Due to the spiral shape, the rapid temperature exchange between the liquids is achieved in a very small space. No cleaning or maintenance required Another advantage is the encapsulation of both liquids from environmental influences. There is practically no cleaning or maintenance effort due to pollution from the environment. The coaxial heat exchanger also does not require any seals that require maintenance. Condenser or evaporator function Coaxial heat exchangers can be used for both condenser and evaporator functions.

Temperature control of gaseous and liquid media Flat tube heat exchangers are generally used as air / air or air / liquid heat exchangers. Flat tube heat exchangers are used where the (exhaust) air is polluted and the installation space is limited. In heat recovery in particular, there are numerous applications for flat tube heat exchangers as so-called exhaust gas / exhaust air heat exchangers. Little installation space and less pressure loss While the rows of tubes in smooth tube heat exchangers consist of round tubes, the rows of tubes in flat tube heat exchangers have a special profile (see illustration). This special tube profile offers advantages over the round profile in certain applications. Flat tube heat exchangers require less installation space than smooth tube heat exchangers with the same exchange area and are therefore also lighter.

Air-water / air-air heat exchanger as smooth tube heat exchanger up to 1,000 ° C Smooth tube heat exchanger as an air / water heat exchanger In the case of air-water heat exchangers (also called gas-water heat exchangers), a temperature exchange takes place between a gas (usually air) and a liquid. As a rule, the liquid medium flows inside the pipes, while the gaseous medium flows around the pipes outside the pipes. Smooth tube heat exchangers can cover various areas of application: heating, cooling and condensing as well as heat recovery. Smooth tube heat exchanger as air-to-air heat exchanger Smooth tube heat exchangers are also often used as air-to-air heat exchangers. In this application, a gas (e.g. exhaust air or exhaust gases) flows inside the pipes and a gas (e.g. fresh air) outside the pipes around the pipes.

Customized air-air heat exchanger for the industry (up to 1.000°C) Hot outgoing air and cold incoming air Very often hot exhaust gas gets out in the environment without any use. On the other hand cold incoming air must be lead into the production process and shall be warmed. This occurs for example very often within drying technology. In this case air-air heat exchangers can be used very efficient in heat recovery. As result you have great potential to save energy expenses. Three types of air-air heat exchangers The Anthermo GmbH delivers three types of different air-air-heat exchangers: cross-flow heat exchanger straight-tube heat exchanger flat-tube heat exchanger The technical figures (for ex. amount of air, temperature, pressure, waste of air) can be different for the air-air heat exchanger. Also the operating conditions and the environment conditions can vary from application to application.
