The PSHE is a cross of shell & tube, and plate & frame heat exchangers. It has corrugated plate for the heat transfer surface, like those of Plate & frame, but they are round or oblong, and are placed into a shell, similar to a tube bundle placed into a shell & tube unit. The plates are welded together with no gaskets between plates. The plate-shell can be put into services where a Plate &Frame cannot be used due to pressure, temperature, or gasket issues; and without the size and cost associated with the shell.
