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.

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.

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.

Heat recovery with the help of heat exchangers In industry, waste heat occurs at many points in the production process, which is often released into the environment without being used. In many cases, energy is even used to cool the waste heat flows from production so that they can be released into the environment. Heat exchangers (also called heat exchangers) are used for heat recovery so that the waste heat generated in the production process can be used again in the company. Gaseous or liquid media Waste heat can be in the form of gaseous media (e.g. warm exhaust air, steam, exhaust gases, etc.) or in the form of liquid media (e.g. hot water or other liquids). With the help of heat exchangers, the waste heat can be recovered from both gaseous and liquid media and then made available to the production process at a suitable point as energy in gaseous or liquid media. This process is known as energy recovery or also as heat recovery.

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.

Every industrial production requires energy in order to make products. Often, electrical or primary energy is induced as heat, used for operation and must then be dissipated, converted or destroyed. Our gwk process engineers analyse and calculate production processes and the overall thermal periphery with the objective of lowering the necessary energy by means of energy recycling, of reducing the energy requirement at the individual stations, of converting energy or using it several times and dissipating it sensibly. The result is considerable energy saving, which results in cost-cutting and contributes to preserving the environment.

Exhaust air purification and heat recovery systems are generally not standard applications, even if individual assemblies are now modular. We have made it our goal to offer our customers the best solution for their task. To do this, we take a step back with our customers in order to gain an overview of the whole. Together we look at how the exhaust air is generated and try to start our concepts right at the point of origin. Only then can we decide which exhaust air system is the most economical when considering the total cost of ownership and compliance with the limit values. Should an extended consideration be necessary, we can accompany you from basic to authority to detail engineering. In addition, it is not uncommon for pilot tests to be offered, which lead to the later real scale of the systems by means of scaleup. With these consulting and engineering services, we offer you a manufacturerindependent package with which you can make the right decision for your company.

Our heatrecovery systems heat fresh air with the thermal energy of exhaust air and can be placed directly on top of a stenter frame. This system can also be retrofitted for older dryers. The benefits are high energy savings which allow payback periods of less than two years, depending on the layout and process, highly efficient platetype heat exchangers with nonstick coating, optimum ease of maintenance by removable drawersized heat exchanger modules, external cleaning of the heatexchangers in a hot water bath with ultrasonic cleaning equipment, high power density, higher than with usual tubetype heatexchangers.

Items that have initially been bagged using a machine from Hugo Beck often need to be shrunk so as to ensure a tight-fitting film and the perfect packaging finish to meet the highest standards. Adapted for each packaging system, we supply the appropriate shrink tunnel in all sizes and performance ranges for the production of high-quality shrink packaging. As such, we manufacture shrink tunnels in a number of versions, with a variety of rods and chains that operate like a link mesh belt. Textile mesh belts are also possible for very light products. In each case, the length of the shrink tunnel depends on the speed of packaging and on the film material selected. State-of-the-art air ducting and heat recovery ensure efficient energy use, helping us to contribute to both protection of the environment and reducing energy costs. The decision on whether to use a shrink tunnel with circulating air or convection principle is defined depending on the individual product application of the customer.

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.

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.
