What are the advantages of gasketed plate heat exchangers?

Below I will explain in detail what advantages gasketed plate heat exchangers have compared to other types of heat exchangers:

● High heat transfer coefficient: The plate surface of gasketed plate heat exchangers usually has various corrugated or grooved designs, which can make the fluid form turbulence at a lower Reynolds number, increase the degree of fluid disturbance, reduce the thickness of the thermal boundary layer, and thus improve the heat transfer coefficient. In general, its heat transfer coefficient is 3-5 times higher than that of shell and tube heat exchangers.

● Large logarithmic mean temperature difference: The hot and cold fluids of most gasketed plate heat exchangers can achieve parallel or countercurrent flow, and the correction coefficient is generally around 0.95. In addition, the temperature difference at the end is small, and the heat transfer temperature difference to water can be less than 1°C, which can more effectively use the temperature difference for heat transfer.

● Good compactness: It consists of a series of thin metal plates and gaskets, with a compact structure and a large heat transfer area per unit volume, which is usually 2-5 times that of shell and tube heat exchangers. Under the same heat exchange capacity, the floor space of the gasket plate heat exchanger is only 1/5 to 1/8 of that of the shell and tube heat exchanger.

● Light weight: The thickness of the plate is generally only 0.4-0.8mm, and the overall weight is relatively light, which is convenient for transportation, installation and maintenance.

● Strong flexibility: The heat exchange area can be easily adjusted by increasing or reducing the number of plates to meet different heat exchange requirements. It can also achieve different process combinations by changing the assembly method of the plate or replacing different plate types to meet various process requirements.

● Easy cleaning: Just loosen the clamping bolts to disassemble the plate, and clean each flow channel comprehensively and thoroughly, which can effectively remove dirt and impurities on the surface of the plate, ensure the performance of the heat exchanger, and reduce maintenance costs.

● Easy maintenance: Parts such as gaskets and plates are easy to disassemble and replace. If a part is damaged or aged, it can be quickly repaired or replaced to reduce the downtime of the equipment.

● Low cost: Under the same material and heat exchange area, the price of gasket plate heat exchanger is usually 40%-60% lower than that of shell and tube heat exchanger.

● Energy saving and high efficiency: Due to the high heat transfer efficiency, heat transfer and exchange can be achieved at low energy consumption, which reduces the operating cost and has good economy in the long-term use process.
