PLATE DESCRIPTION

AND CONSTRUCTION

SUPERCHANGER plate corrugations are available in four

patterns. Depending on the applications, the GF, UX, SX,

GC and GX Series plates are used to achieve maximum heat

transfer.

UX, SX and GC Series plates: Herringbone (chevron) pattern

is ideally suited for handling aqueous solutions.

GF Series: Wide gap and parallel (washboard) patterns are

designed for applications where there are high viscosity ﬂ uids or

ﬂ uids containing ﬁ bers or coarse particles.

GX Series: An asymmetrical four quadrant plate suited for low

viscosity and close temperature approach applications or processes

involving two vastly different ﬂ ow rates. It is also well suited for

equal ﬂ ows and close approach.

All plates are manufactured from die-formed sheet metal in

virtually any material that can be cold worked, such as stainless

steel, titanium, Alloy C-276, Alloy-20, etc. There are grooves

around the circumference of the plates which accept the sealing

gasket and also add reinforcement because of the ribbed edges.

Fluid passage holes are pierced at the corners of each plate. The

number and location of the holes is dependent upon the design

conditions.

The gaskets are single piece, molded construction, and generally

bonded to the plates with Pliobond 30 adhesive. The gasket

material is selected for compatibility with the ﬂ uids being

processed and the operating temperatures.

Each plate also contains ﬂ ow directors at the top and bottom

of the heat transfer surface in the port hole areas, which evenly

distribute the ﬂ uids. Some plates require a hanger, which attaches

the plate to the upper guide bar. For most models, the upper

guide bar is the plate’s sole support member in the frame, while

the lower guide bar serves as an alignment member in all plates

except the UXP-005 and the UXP-001, which are supported by

the lower guide bar. See Figures 4 through 7 and Tables 1a and

2 for speciﬁ c models.
