Preface
Storage in packing box
If storage of the heat exchanger after delivery is known
in advance, inform Alfa Laval when ordering the heat
exchanger to ensure that it will be properly prepared for
storage before packing.
Indoor storage
• Store inside a room with the temperature between
15 and 20°C (60–70°F) and humidity up to 70%. For
outdoor storage read “Outdoor storage” on this page.
• To prevent damage to the gaskets, there should not be
any ozone-producing equipment in the room such as
electric motors or welding equipment.
• To prevent damage to the gaskets, do not store organic
solvents or acids in the room and avoid direct sunlight,
intensive heat radiation or ultraviolet radiation.
• The tightening bolts should be well covered with a thin
layer of grease. Refer to “Closing” on page 25.
Outdoor storage
If you need to store your heat exchanger outdoors, follow
all the precautions in the “Indoor storage” section as well as
the precautions listed below.
The stored heat exchanger shall be visually checked every
third month. When closing the packing it shall be restored
to original condition. The check includes:
• Greasing of the tightening bolts
• Metal port covers
• Protection of the plate pack and gaskets
• The packing
Taken out of service
If, for any reason, the heat exchanger is shut down and
taken out of service for a long period of time, follow the
precautions in the section ”Indoor storage” on this page.
However, before storage the following actions must be
done.
• Check the measurement of the plate pack (measure
between frame plate and pressure plate, the
A
dimension).
• Drain both media sides of the heat exchanger.
• Depending on media, the heat exchanger should be
rinsed and then dried.
• The connection should be covered if the piping system
is not connected. Use a plastic or plywood cover for
the connection.
• Cover the plate pack with non-transparent plastic film.
Start-up after long-term out of service
If the heat exchanger has been taken out of service for an
extensive period of time, longer than one year, the risk of
leakage when starting up increases. To avoid this problem
it is recommended to let the gasket rubber rest to regain
most of its elasticity.
1. If the heat exchanger is not in position, follow the
instructions “Installation” on page 11.
2. Note the measurement between frame plate and
pressure plate ( A dimension).
3. Remove the feet attached to the pressure plate.
4. Loosen the tightening bolts. Follow the instructions
“Opening” on page 20. Open the heat exchanger until
the measure
A is 1.25.
5. Leave the heat exchanger for 24–48 hours, the longer
the better, for gaskets to relax.
6. Re-tighten according to the instructions “Closing” on
page 25.
7. Alfa Laval recommends a hydraulic test should be
carried out. The media, usually water, should be
entered at intervals to avoid sudden shocks to the heat
exchanger. It is recommended to test up to the Design
Pressure. Refer to the PHE drawing.
Environmental compliance
Alfa Laval endeavours to perform its own operations
as cleanly and efficiently as possible, and to take
environmental aspects into consideration when developing,
designing, manufacturing, servicing and marketing its
products.
Unpacking
Packing material consists of wood, plastics, cardboard
boxes and, in some cases, metal straps.
• Wood and cardboard boxes can be reused, recycled or
used for energy recovery.
• Plastics should be recycled or burnt at a licensed waste
incineration plant.
• Metal straps should be sent for material recycling.
Maintenance
• All metal parts should be sent for material recycling.
• Oil and all non-metal wear parts must be taken care of
in accordance with local regulations.
Scrapping
At end of use, the equipment shall be recycled according
to relevant, local regulations. Besides the equipment itself,
any hazardous residues from the process liquid must be
considered and dealt with in a proper manner. When in
doubt, or in the absence of local regulations, please contact
the local Alfa Laval sales company.
