The main components of the DHP Plate Heat Exchangers: |
|
 The plate pack comprises of a number of heat plates, according to the heat transfer surface required. |
|
Gaskets on the plates ensure that the flow channels are securely sealed from each other.
The gasket also determine the direction of flow within the exchanger. |
|
The frame enclosing the plate pack is held together with tightening bolts. |
|
Connections for incoming and outgoing fluids are usually in the fixed frame of the heat exchanger.
In the case of multi pass flow, connections have to be in the fixed frame and the movable frames. |
| |
Operation |
|
Adjacent plates form flow channels carrying alternately hot and cold fluids throughout the plate pack.
Normally, single pass heat exchangers are used, permitting 100% counterflow of both products.
All port connections are located in the fixed frame plate providing a low maintenance installation.
In cases of low temperature differences, or where these differences are to be fully utilized, multi pass Plate Heat Exchangers become more economical.
Provided the number of passes is the same for both fluids nearly 100% counterflow will be achieved. |
