5.11 - 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.

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.
