الوصف

All welded plate and frame heat exchanger is a new-concept type. It looks like gasket and frame plate heat exchanger, and integrates advantages of general plate heat exchanger (efficient heat transfer and compact construction) and shell and tube heat exchanger (suitable for high temperature and pressure). With internal countercurrent, it can achieve the terminal temperature difference which cannot meet by other all welded plate and frame heat exchanger. Its cover board could easily open for clean, and the liquid shear stress appear in passage is obvious higher than other welded plate heat exchanger. At the same time, its special flow design enables it to be used as an efficient condenser. 



Advantages of All Welded Plate and Frame Heat Exchanger 

1. CIP cleaning for plate

2. Laser welding for plate, no gasket

3. High heat transfer efficiency with almost all plate surface for heat exchanging

4. Small floor area, be equal to gasket and frame plate heat exchanger 

5. Flexible connection diameter in/out, adaptable design 

6. Low cost of using and maintenance



Heat Transfer Plate 

Heat transfer plate is pressed by imported metal plate with thickness ranging from 0.8mm to 1mm. Corrugated shape is similar to the gasket and frame plate heat exchanger. But there is no hole and non-heating transfer area on plate, so almost all plates can be used for heat transfer to improve the efficiency of plates. Meanwhile, different layouts of nozzle substantially eliminate water distribution between plates and help to avoid "dead zone phenomenon.
