Shell and plate heat exchanger

liquid/liquidindustrial

A heat exchanger is a device that facilitates the process of heat exchange between two fluids that are at different temperatures. Heat exchangers are used in many engineering applications, such as refrigeration, heating and air-conditioning systems, power plants, chemical processing systems, food processing systems, automobile radiators, and waste heat recovery units. Heat exchangers are critical elements in every process plant. While the majority of exchangers are the shell-and-tube type, there are several additional important types. manufactures shell-and-tube type heat exchangers in different capacities suitable for different processes in all areas of the industry such as the marine sector, oil refinery and food sector. Advantages • Cheapcomparedtoplateheat exchangers, • Relatively simple design and easy to maintain, • Suitable for higher pressures and temperatures compared to plate heat exchangers, • Pressure drop (delta P/ΔP) is less than a plate heat exchanger, • Easytofindand isolateleaking tubes, • Tubes can be 'double walled' to reduce the likelihood of the shell side fluid leaking into the tube side fluid (or vice versa), • Easytoinstallsacrificial anodes, • Donotfoulaseasily asplateheat exchangers. Disadvantages • Lessefficient than plate heat exchangers, • Requiremorespaceto open andremovetubes, • Cooling capacity can not be increased, but a plate heat exchanger's can be.
