Plate Heat Exchanger 5 EN

Function
The fusion plate heat exchangers consist of a pack of
bonded corrugated metal plates with ports for the
passage of the two fluids between which heat trans-
fer will take place.
The media in the heat transfer are led into the bond-
ed plate pack through portholes at the corners and
are distributed into the passages between the bond-
ed, corrugated plates.
The heating surface consists of thin corrugated
plates stacked on top of each other. In the fusion
process at high temperature channels are formed
between the plates and corner ports are arranged
so that the two media flow through alternate chan-
nels, always in counter-current flow. The contact
points are also bonded to withstand the pressure
of the media handled.
The fusion plate heat exchanger is typically
used for heating or cooling media with low to
medium viscosity. A specific fusion plate heat
exchanger is dimensioned for a specific duty,
set out in the product documentation, and
should not be used in any other way without
consulting the supplier.
