Alfa Laval MX25 - Multi-Pass; Identification of Plate Side

3.4 Multi-pass
Multi-pass sections can be created by using turning plates with 1, 2 or 3
unholed ports. The main purpose is to change the flow direction of one or both
fluids.
An example of where multi-pass can be used is in processes that require
longer heating periods if the media requires slower heating.

Identification of plate side
The A side of the plates (symmetric pattern) are identified by a stamp with the
letter A and the model name at the top of the plate (refer to image 1 below).
Plates with asymmetric pattern has two possible sides for placement of the
gaskets. The pattern is marked A W for the wide-side image 2 and B N for
normal-side image 3.
Plates with WideGap pattern has two possible sides for placement of the
gaskets. The pattern is marked A R for the wide-side (Ridge) image 2 and B V
for normal-side (Valley) image 3.
