1 Shell and tube heat exchangers Model series

2 Quality shell and tube exchangers from specialists ViFlow has the exclusive right to sell FUNKE s products in Finland. The company was founded in 1974 and focus on designing and manufacturing of heat exchangers for nearly all industrial applications as well as also for the HVAC sectory. The partnership with FUNKE broadens ViFlow s product base, we can now offer the right heat exchanger type for every customer. In the area of shell and tube heat exchangers we can offer a mature product range of special models for almost all requirements in machine and plant enginering. Maximum quality requirements and customer-oriented solutions characterise the brand FUNKE. Customised process gas coolers with operating pressure of 400 bar and above are nothing unusual. However, with the series models we already offer our customers in our standard programme a comprehensive and high quality range of products for all current requirements in international machine and plant engineering. The customer receives thermodynamically optimised units which are manufacture in defined graduations e.g. with regard to shell diameter and shell and tube length and which are available at short notice.

3 Shell and tube exchanger -structure and functioning The shell and tube heat exchanger is a nonfired pressure system consisting of two separate pressure chambers (shell chamber and tube chamber). Separated by the internal tube wall, two media flow past one another with such alignment that, if there is a temperature difference, they will mutually exchange heat without mixing in the process. One medium flows through the shell chamber and the second medium flows through the tube chamber. The flow through the shell chamber will be controlled by baffles such that there is as much cross-flow to the tubes as possible. The form and spacing of the baffles will be adapted to the relevant operational use. Depending on effectiveness, speed and pressure loss the flow through the tube chamber will be effected by a single pass or by multiple passes. With the exception of radiation losses, the input heat quantity is the same as the output heat quantity. Components of the shell and tube heat exchanger Heat exchanger shell 2. Connection shell 3.

Apparatus seal Design of a CP standart unit using 3D software However, an effective heat exchange can only occur if there is a sufficient temperature difference. The greater the temperature difference is the smaller will be the re-quired heat transfer surface. The heat transfer performance of a heat exchanger is the product calculated from the mean logarithmic temperature difference, the heat transfer surface and the heat transfer coefficient. The latter will be largely determined by the flow characteristics of the media, that is by the geometric design. On the other hand, the supplier of heat exchangers must have a wide application know-how with regard to the thermodynamic properties of special media at pertinent pressures and temperatures. This also concerns the issues of fouling factor and material compatibility. The calculation and design of FUNKE heat exchangers is effected with worldwide leading programs (e.g. HTRI, Heat Transfer Research Institute, USA) as well as with FUNKE- Software which is already used internationally.

7 SWF/SWP/SSWF/SSWP Safety heat exchanger for usage where leakage or mixing of operating media is not acceptable. In case of leakage of the shell or tube side the corresponding change in pressure is detected by the pressure control device in the safety space and is signalled accordingly. SAFETY HEAT EXCHANGER Three chamber devices with straight internal tubes and fixed ( F ) or removable ( P ) tube bundle. Each individual tube has a smaller internal tube, which prevents a mixing of the following operating media. Double tube sheets produce the enclosed safety space, wich is filled with a special barrier fluid and is checked for pressure changes. This type is used when following issues have special importance: Environmental protection Health protection Cost of operating resources PED 97/23/EG AD 2000 Chemical reactions between operating medias can be dangerous. Contaminated liquid removal from surface water or boiler water. Closed circles for refilling media.
