Plate Heat Exchangers (PHE) have been used
since the 1960's by the process industry for a range of
heating and cooling duties associated with heat recovery,
with the aim of maximizing process efficiency. Additional
reason for using PHE's as opposed to the alternative Shell
and Tube are low temperature approach capabilities, space
and economy savings. Plate heat exchangers consist of a
series of corrugated plates with a peripheral gasket that
are held within a steel frame. All liquid contact surfaces
are manufactured in stainless steel that eliminates
corrosion due to aggressive media. If stainless steel is not
suitable other higher grade materials are available, such as
Titanium or Hastalloy.
Gasket selection is also considered for each application,
such as Nitrile, RCB, EPDM, Viton
DHT Plate Heat Exchangers are Work Cover Approved and
manufactured to ISO 9001 quality standards. Products meet
international heat exchange standards.
Features Of The PHE
High Performance :
The total heat transfer co-efficient of the PHE is
2,000?6,00O Kcal/m2/hrC. The value is 3 to 10 times higher
than the traditional shell and tube heat exchanger.
High Economic Tendency:
The PHE can maximise energy transfer efficiently from the
unique combination of high turbulence and thin plate
technology for any given unit size.
Maintenance costs are also reduced due to it'scompact size.
Variety of Options:
The PHE has been developed to allow many types of plates and
gaskets for a large number of applications.
Changing the number of plates or configuration of the plate
pack allows for a change in duty requirements in the
shortest possible time.
Maintenance is also greatly simplified, should
Re-gasketing or the cleaning of the plate surfaces be
required.
Excellent versatility :
The PHE can carry out many kinds of processes from ice
making, cooling, heating and condensing or evaporation, with
one set of suitable plates
