All Welded Plate and Frame Heat Exchanger


All welded plate and frame 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 cannot 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 use as 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

 

Main Structures for All Welded Plate and Frame Heat Exchanger

Non-Dismountable Type Welded Plate and Frame Heat Exchanger, Fully Enclosure for frame, more compact in structures, less investment, Suitable for clean fluids in both sides.

 

One Side Dismountable Type Welded Plate and Frame Heat Exchanger, Half openable for Frame, one side could apply for the fluids which need regular clean and maintenance.

 

Two Sides Dismountable Type Welded Plate and Frame Heat Exchanger, full openable for both sides, like Compabloc Type heat exchanger.

 

Heat Transfer Plate Model

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 eliminates water distribution between plate and “dead zone” phenomenon.
