Product Details

  The structure of the plate heat exchanger is compact and the gap is small, so the heat transfer area per unit volume is increased. Its installation area is about 1/2 to 1/3 of the shell and tube type. When the volume of a shell is 1 cubic, its heat transfer area is about 80 square meters.In plate heat exchangers, only the shell plates of the heat transfer plates are exposed to the atmosphere.Therefore, the heat loss is negligible and no thermal insulation measures are required. One of its characteristics in operation and maintenance is that it is easier to assemble and disassemble. The heat exchanger does not have to be completely disassembled, and the compression bolts can be loosened to remove the plates for cleaning and replacement of gaskets and plates. This is particularly important for materials that are prone to deposit in heat transfer media. The heat exchanger relies on a gasket between every two plates to prevent material leakage. Therefore, the total length of its sealing perimeter is very long, and preventing gasket leakage is an important link.

  The temperature, pressure and chemical stability that the gasket can withstand often also become the temperature and pressure limits for its use and the range of materials allowed. Because the gap between the heat transfer surfaces is small and there are irregularities on the heat transfer surfaces, it is larger than the traditional smooth pressure loss. Plate heat exchangers have lower working pressures. The all-welded plate heat exchanger does not use any non-metallic sealing materials and can have high temperature and pressure resistance. It can be applied to extreme working conditions with a working temperature of 300 ° C and a pressure of 3.0Mpa.
