HOW IT WORKS.
uses a combination of chevron-style heat transfer
plates sequenced between a frame plate and pressure
plate. The heat transfer plates have holes at the
four corners. These holes form a header that
distributes the respective fluids to the opposite
sides of each plate when the plates align. The
fluids are confined to the heat transfer surface of
the plate or the port as appropriate with elastomer
Countercurrent flow is obtained with a given fluid
traveling up one side of a plate and the other fluid
down the opposite side of the plate. The plate’s
chevron patterns create metal to metal contact
points between adjacent plates for added strength.
differential pressures equal to the design pressure.
The entire assembly is held together with tightening
bolts. Carry/guide bars are used to obtain the
proper alignment. The Plateflow design is extremely
AT A GLANCE
Working principle The
basic plate heat exchanger consists of a series of
thin, corrugated plates that are gasketed or welded
together (or any combination of these) depending on
the liquids passing through and on whether it is
practical to be able to subsequently separate the
plates, for whatever reason.
The plates are then
compressed together in a rigid frame to create an
arrangement of parallel flow channels. One fluid
travels in the odd numbered channels, the other in
GASKET PLATE HEAT EXCHANGER ADVANTAGES
Plates are formed in a wide variety of patterns and
materials to meet your heat transfer needs.
Since the gap between plates is small, a plate heat
exchanger contains only low quantities of process
fluids reducing cost due to lower volume
Plate arrangement can be changed and plates can be
added or removed. It is possible to install several
sections in one frame and permit several process
steps in a single unit.
Under the gasket groove the heat exchanger plates
are integrally reinforced on both sides.
Fouling of the heat transfer surfaces of an Danfoss
Gasket plate heat exchanger is extraordinarily low.
The high induced turbulence yields a self-cleaning
effect which minimizes fouling.
The unique design of Danfoss Gasket plates allows
for optimum alignment during assembly for greatest
With high heat transfer coefficients and a true
counter-current flow path, Danfoss Gasket plate heat
exchangers can cool hot fluids to within one degree
of the cold fluid making heat recovery in excess of
96% technically and economically possible.
Units can be cleaned without dismantling by
clean-in-place (CIP) systems, by reverse flow
cleaning or by addition of suitable cleaning fluids.
Plate removal is easily accomplished by releasing
the tightening bolts that compress all of the heat
