Fully Welded Heat Exchanger:
The fully welded plate heat exchanger is a new-concept type. It looks like gasket and frame plate heat exchanger to be with 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 can not meet by other full welded heat exchanger. Its cover board could be 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 can to used as efficient condenser.

Advantages of Fully Welded Heat Exchanger:
1. CIP cleaning for plate
2. Laser welding for plate, no gasket
3. High hear 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 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 of plate can be used for heat transfer to improve the efficiency of plate. Meanwhile, the different layout of nozzle substantially eliminate water distribution between plate and “dead zone” phenomenon.
