• Significant reduction in footprint
- 20 % of shell & tube
is possible
• Significantly lower cost! Competitive against other compact heat exchangers
• Economic use of exotic alloys
• Low hold up
 Plate & Shell Heat Exchangers
are extremely efficient due to the high turbulence created
by the
complex geometry of each plate passage. The high turbulence
leads to much higher heat transfer co-efficient than conventional
heat exchangers which in turn means that less heat transfer
surface is required to perform a given duty. This means not
only that the exchangers are compact but also that they are
cost effective as less material is used in their manufacture.

• Added security against
leakage
• No gaskets to deteriorate or replace
Our range of Plate & Shell
Heat Exchangers utilises a fully welded plate pack at its core.
Unlike conventional plate heat exchangers they do not have
metre upon metre of gaskets which degrade in service. The fully
welded
pack gives high integrity and resists temperature and pressure
cycling and the effects of freezing.

In house testing verified by a
3rd Party inspection agency has demonstrated that it is possible
to continually freeze a PSHE unit without any detrimental mechanical
effects.

• -200°C
to + 900°C possible
• Full vacuum to 100 bar g possible
Due to the exchanger being housed in an outer shell, the pressure and temperature
capabilities can be extended way beyond that which a conventional plate heat
exchanger can tolerate.
The outer shell construction is a pressure vessel therefore the normal pressure
vessel codes can apply.

Unique construction prevents failures
associated with other compact heat exchangers.
Because the platepack is only welded in 2 dimensions, it is
able to expand and contract within
the outer shell.
The Vahterus
Plate & Shell is proven
in temperature shock applications where the exchanger has been subjected to
temperature differentials are as high as 280°C.back

Our own test work has demonstrated
that the Vahterus Plate & Shell can tolerate
very high pressure cycling loads without failure.

• Openable units are possible
to allow access for shell side cleaning
• Cassette type plate pack allows quick and easy re-fitting
The Plate & Shell Heat Exchanger concept allows for either a fully welded
shell, or alternatively openable units are available which allows the exchanger
to be opened and the plate pack withdrawn for access to the shell side for
inspection and cleaning.back to top»

• 1°C possible As the flow paths within the
Plate & Shell
Heat Exchanger can be arranged to be in pure counterflow
ie. in opposing directions, it is possible to achieve approach
temperatures down to 1°C . This is impossible in a shell & tube
heat exchanger. This highly efficient method of arranging the
flows together with the high turbulence generated within the
plate passages leads to an extremely compact heat exchanger.
