1. Clean and convenient
After the compression plate of plate type heat exchanger is removed,the plate bundle can be loosened.Remove the plate and carry out mechanical cleaning.

2. Have a simple change of the heat area or process combination
Adding(or cut)the sheet is needed to reach the demand of adding(or cutting)the heat exchange area.

3. The price is not high
On the premise of using the same data, the production cost is to be lower than that of the shell-tube heat exchanger because the layout requires less data.

4. Light weight
The plate thickness of plate type heat exchanger is only 0.6 ~ 0.8 mm while the thickness of heat exchanger shell-tube heat exchanger is 2.0 ~ 2.5 mm;the shell of shell-tube heat exchanger’s layout is much heavier than that of the plate type heat exchanger;in the case of the same heat transfer mission, the heat transfer area required by plate type heat exchanger is smaller than that of shell and tube heat exchanger.

5. Small footprint
The plate type heat exchanger has a compact layout, and the heat transfer area per unit volume is 2 / 5 times that of the shell and tube heat exchangers.Also,it doesn’t need to reserve a controlled maintenance site like shell and tube heat exchanger.Therefore, when the same heat transfer mission is completed, the floor area of plate heat exchanger is about 1/5~1/10 of that of shell and tube heat exchanger.

6. High heat transfer coefficient
The layout of the shell and tube heat exchanger is excellent in terms of strength,but it is not effective in terns of heat transfer due to the existence of Baffle-shell, baffle-heat pipe, by-pass between control-housing in the activity of fluid in shell side.The fluid passing through the bypass does not fully participate in heat transfer.There’s no no bypass of plate type heat exchanger while the ripple of the plate can make the fluid turbulent at a relatively small flow rate.Therefore, the plate type heat exchanger has a higher heat transfer coefficient, which is usually 3 / 5 times that of the shell and tube heat exchanger.
