Pagina afdrukken5.11 - Increasing the transfer area
It is possible to add an even number of extra
plates to an existing heat exchanger, provided
you:
• Check the maximum plate capacity of the heat
exchanger.
• If the length is insufficient, provide new
carrying bars and threaded rods.
• Replace the nameplate and the plate
arrangement drawing
with the new ones provided by CIPRIANI.
• Leaks often occur when plates with new
gaskets and plates with old gaskets are used
together (due to difference in toughness).
We therefore strongly recommend replacing all
worn gaskets with new ones.
5.12 - Spare plates
Plates may be replaced individually or
altogether. In this last case, however, it is
recommended to replace all the gaskets (see the
previous section).
• If only a few plates are replaced, indicate the
sequence of the plates to be replaced shown on
the plate arrangement drawing.
5.13 - Troubleshooting
FLUID LEAKS BETWEEN PLATE
PACK AND FRAME
PROBLEM
Leak detected at the bottom of the pack.
POSSIBLE SOLUTIONS
° Make sure that all the bolts are correctly
tightened.
° Make sure that there is no mechanical stress on
any of the connections.
° Reposition or replace the gasket on the initial
or end plate.
° Check the internal surface of the fixed head for
defects.
° Make sure that there are no foreign bodies
between the initial plate and the fixed head.
° Test the initial/end plate for signs of damage
(cracks, holes).

FLUID LEAKS BETWEEN
CONNECTIONS AND FRAME
PROBLEM
Fluid leaks where a connection passes through
the fixed head.
POSSIBLE SOLUTIONS
° If welded connections are used, check the
condition of the welds.
° If cracks are found, contact your Atlantic
consultant before attempting any repairs.
° If other connections are used, contact your
Atlantic consultant.
FLUID LEAKS FROM THE PLATE
PACK PROBLEM
Leak detected from plate pack.
POSSIBLE SOLUTIONS
° Measure the tightening dimension and check it
against the nameplate. Tighten if need be.
° Mark the area around the leak with a felt-tip
pen then open the heat exchanger and inspect
the area.
° Check the sequence and alignment of the
plates.
° Check the condition of the gaskets (correct
position, overall condition, elasticity). Reposition
or replace the gaskets as needed.
I
INTERNAL LEAKS WITH mixing of
fluids
Contact Atlantic as quickly as possible.
PROBLEM
The fluids in the heat exchanger are mixing
together at the unit's outlet.
POSSIBLE SOLUTIONS
° Make sure that the hydraulic connections are
correct.
° Disassemble the heat exchanger and inspect
the entire surface of each plate for cracks and
holes with penetrant. Replace any
damaged plates.
