Plate heat exchanger This heat exchanger is fluid, fluid steam carries on the heat change the ideal equipment. It has the heat transfer efficiency high, the heat los young, the structure compact dexterous, the area young, the installment clean convenient, the application widespread, the service life is long and so on the characteristic. In the same pressure loss situation, its heat transfer coefficient tubular heat exchanger is higher than 3-5 time, the area for the tubular heat exchanger 1/3, the heat recovery rate may reach as high as above 90%. The disc heat interchanger widely applies to profession and so on metallurgy, petroleum, chemical industry, food, drugs manufacture, ships, spinning and weaving, papermaking, is heats up, cooling, the heat recovery fast, is antiseptic and so on the use fine equipment
