Each plate is provided with a gasket, which seals the flow gaps to atmosphere and the media from one another. The plate package is mounted in a rack consisting of a fixed number of plates. Two pressure plates clamp this package together with tie rods. Single pass and multi-pass arrangements are standard with a surface area of up 1500m2 in one unit. Pure counter flow is employed to achieve maximum possible heat transfer.       

Types of attachments.

• Contact adhesive.
  This is the most typical adhesive method. After assembly the glue is often oven cured to ensure a good bond. However, the gaskets can normally be removed by hand leaving behind a small amount glue in the gasket groove.
• Two part epoxy resin.
  This process uses a hardener to complete the curing process. This forms a superior bond which stops the gasket from being easily removed from the heat transfer plate.
• Double sided tape.
  This process is used to hold long pieces of straight gasket on larger plate heat exchangers. It would not be used to hold the entire gasket to the heat transfer plate.

MECHANICAL ATTACHMENTMost modern plate heat exchangers use a form of mechanical attachment to fix the gaskets to the heat transfer plates.

• Pros. The gaskets can be easily removed and replaced, especially on site, as the gasket sealing area remains clean (free from glue residue).
• Cons. The gaskets will become detached from the heat transfer plates when pressure washing on site or through incorrect / rough handling. Care must be taken when tightening the heat exchanger to ensure the gaskets remain in the gasket groove - occassional checks should be made whilst tightening down so any gaskets that have moved out of the groove can be pushed back in.
