The plate heat exchanger frame and plate are removable. It's easy to disassemble, plate can be cleaned at any time, but all welded plates are welded together can not disassemble. The customer can use the CIP method to clean it.

Plate heat exchanger


Plate heat exchanger is a high efficiency heat exchanger, which is made up of a series of metal sheets with certain corrugated shape. A thin rectangular channel is formed between various plates, and heat is exchanged through the plates. It's an ideal equipment for liquid-liquid and liquid-vapor heat exchange, has the characteristics of high heat transfer efficiency, low heat loss, compact and lightweight structure, small floor area, wide application and long service life. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of tubular heat exchanger, occupying one third of the area of tubular heat exchanger, and the heat recovery rate can be as high as 90%.


All welded heat exchanger


A all welded heat exchanger is a new generation product which integrates the advantages of a detachable plate heat exchanger and shell-and-tube heat exchanger. Its introduction makes up for the application gap of the removable plate heat exchanger. At the same time, its high temperature, high pressure, and strong corrosion resistance ensure the replacement of most working conditions of the traditional shell and tube heat exchangers.
The fully welded heat exchanger has a corrugated plate structure similar to the plate heat exchanger. At the same time, it adopts more advanced Full-welding process seals, no gasket design, and the selection of various metal and alloy materials to ensure that MAX fully-welded heat exchanger is suitable for almost all heat transfer process occasions with temperature ranging from 5 to 500 oc and working pressure ranging from vacuum to 60bar. Its compact structure design, efficient heat transfer performance and convenient and flexible use determine that it has inherent superiority to completely replace the traditional shell and tube heat exchangers.
