Where do I use a Plate & Frame exchanger?

There is no single answer to this question and there is always the exception. Generally PHE’s are used in lower pressure applications <300 PSI and / or lower temperature applications <300 °F.
They work very well when a large amount of surface is needed to transfer the heat. An example of this would be when there is a temperature cross. PHE technology and sales jumped in the 1970’s when energy prices were high because of their high efficiency.
Another benefit of PHE’s is that they are compact, very large volumes of product can be heated or cooled in a very small space.

In the southeast United States, we have seen an increase in the interest for PHE’s due to the drought conditions which have existed over the past few years. The design characteristics of a PHE allow for greatly reduced cooling water flows.

Every application has its own unique problems. Post it here and let’s discuss it.
