Plate And Frame Exch.

This kind of exchanger does have specific space requirements for maintenance. You asked the following questions:
- How do we remove the Plates in Plate and frame Exchanger?
The plates are removed from the normal P&F exchanger by shutting down the exchanger, loosening the bolts, sliding the plates apart then removing them from the frame.
- Do I need to provide the space for maintenance?
Yes! You need to keep one side of the P&F exchanger completely free for the removal of the plates. The width of the free space shall be the full width of the plate (or exchanger).
- Do we need to provide space throughout the overall length of exchanger or only near to plates?
Yes! The length of the free space shall be the length of the exchanger.

- I have never seen these exchangers in front of me. I seen only in drawings (there is no detail, only overall dimensions).

You asked:
- Is possible to take out the plates from directly from side of exchanger?
Depending on the actual Brand and model of P&F exchanger I would say , Yes! you remove the plates directly from the side.
- Or we have to remove the plates through carrying bar (located top side of the plates)?
No! you would not remove the plates "through" the carrying bar.
- It means we have to remove the support column first then we will remove the pleats through carrying bar.
No, you would not remove the support column.
