Smooth tube heat exchanger

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-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.

Temperature exchange between a gas and a liquid In the case of air-water heat exchangers (also called gas-water heat exchangers), there is a temperature exchange between a gas (usually air) and a liquid. Finned heat exchangers can cover various areas of application: - heating and evaporating, - cooling and condensing as well as heat recovery. In this context, lamellar heat exchangers are also called air heaters or air coolers. Air-water heat exchangers are often also used as exhaust gas heat exchangers or flue gas heat exchangers in order to recover the energy from warm or hot exhaust gases. Lamella packs for a large exchange area In order to achieve the largest possible exchange surface between the air and the medium (liquid) within the heat exchanger, lamellas or lamella packs are attached to the pipe system.

Temperation of fluids Pillow plates are used everywhere where liquids must be temperated. In dependence of application the liquids can be cooled or heated. Cause of this wide range of applications pillow plates are used in the process industry, in the cooling industry and in a lot of other industries. Pillow plates are also know as heat exchanger plates, evaporator plates, cooling plates /sheets and thermo plates / sheets. Pillow plates as air-/water-heat exchanger Additionally to the temperation of liquids pillow plates are also used as air-/liquid heat exchangers. In case of polluted or wasted air and if there are high demands for cleaning, more and more pillow plates are used as air-/water-heat exchanger. The large exchange surface and the good possibilities for cleaning are important features for this type of heat exchanger.
