Description
Multi-pass
M ulti-pass sectio ns can be created by using turnin g plates wi th 1, 2 or 3 unholed ports. The
m ain purpose is to c hange the flow direc tion of one or both fluids.
For some units, a partiti on plate is required to support the unholed ports in the turning plates. A
transition plate also needs to be added to the pack to prevent media from coming into co ntact
with the part ition plate or pr essure plate.
An example of where multi-pass can be used is in processes that require longer heating periods
if the media requires slower heating.
