Finned tube heat exchanger


Finned tube heat exchanger Maxxtec

Finned tube heat exchanger for heat transfer between air, gas and liquids or steam. Heat exchanger with finned heating surfaces, so-called finned tube heat exchanger, offer the possibility of heat transfer between gases and liquids significantly space-saving and is more efficient to implement than it is possible with straight tubes. Maxxtec finned tube heat exchangers are designed to transfer heat from clean air and gases with high efficiency on liquids or vapors, and vice versa. In this way the media can be heated, cooled or condensed, in a closely space. Finned tube heat exchangers can be used for different applications and in a variety of designs. Maxxtec offers various heat exchangers for economizer, air heater, heaters for gases, air heaters or capacitors in fin-tube design.

Application examples for finned tube heat exchanger:

Finned tube heat exchangers are often used in power plants as an exhaust gas heat exchanger to increase the efficiency factor. Further applications in power plants are the preheating of combustion air as well as the condensation of exhaust steam from steam or ORC turbines.

In industrial dryers finned tube heat exchangers will be used for heating of air by hot water, steam or thermal oil in large quantities.

In many industrial production processes, such as for the air conditioning of buildings, finned tube heat exchangers are used as an air cooler for cooling down or re-cooling of liquids. Due to the problems with Legionella, the high consumption of fresh water, as well as the elaborate water treatment, closed cooling circuits with finned tube heat exchangers will be used instead of cooling towers with open water circuit.
