Applications
Semi-welded plate heat exchanger for general heating, cool-
ing and heat recovery of aggressive media in one channel.
Standard design
The plate heat exchanger consists of a pack of corrugated
metal plates with portholes for the passage of the two fluids
between which heat transfer will take place.
The plate heat exchanger consists of a pack of corrugated
metal plates with portholes for the passage of the two fluids
between which heat transfer will take place.
The plate pack is assembled between a fix frame plate and a
movable pressure plate and compressed by tightening bolts.
The semi-welded plates combine the flexibility and service-
ability of the gasketed heat exchangers with the assurance
against leakage of the welded heat exchangers. In the plate
arrangement, every other channel is welded, and every other
channel is gasketed. The number of plates is determined by
the flow rate, physical properties of the fluids, pressure drop
and temperature program. The plate corrugations promote
fluid turbulence and support the plates against differential
pressure.
The semi-welded plate heat exchanger is provided with gas-
kets specifically designed to resist aggressive media. The
non-aggressive media flows in the gasketed channels. This
construction means that it can easily be dismantled, for
example for exchanging gaskets or for inspection and clean-
ing of the gasketed channels.
Corrosion-resistant plate materials, the absence of pressure
retaining welds, double gasket seals, and a flexible yet vibra-
tion-resistant design - to assure long life and trouble free
operation.
The frame plate and the pressure plate are suspended from
an upper carrying bar and located by a lower guiding bar,
both of which are fixed to a support column.
Connections are located in the frame plate or, if either or both
fluids make more than a single pass within the unit, in the
frame and pressure plates.
