1 Introduction
This manual provides information needed to install, operate and carry out
maintenance of your gasketed plate heat exchangers.
The following models are covered in this manual:
• T6
• T10
1.1 Intended use
The intended use of this equipment is to transfer heat in accordance with a
decided configuration.
All other use is prohibited. Alfa Laval will not be held responsible for injury or
damage if the equipment is used for any other purpose than the intended use
described above.
1.2 Reasonably foreseeable misuses
• Do not lift or transport the crate nor the equipment in any other way than
stated in this instruction manual.
• Connect a pipe in the way it is meant to be connected to the plate heat
exchanger. Gasket and lining can be damaged if a pipe is connected in the
wrong way.
• On semi-welded units it is a safety issue if the wrong pipe is connected to
the wrong port, double check that the correct media is connected to the
correct port according to the PHE drawings.
• It is a risk to damage the hangers if you hang in or move many plates at a
time. It is recommended to handle one or a few plates at a time.
• When setting the A measure, always tighten the bolts crosswise, evenly,
and a little at a time to avoid diagonal shifting and snaking. For information
regarding the A measure, see Section A measure in the Chapter
Description.
• After a stop, increase the flow gently to avoid deformed plates.
• At a start, raise the temperature gently to avoid cracks in the gaskets or
create a blow-out.
1.3 Prior knowledge
The plate heat exchanger shall be operated by persons who have studied the
instructions in this manual and have knowledge of the process. This includes
knowledge of precautions regarding media type, pressures, temperatures in
the plate heat exchanger as well as specific precautions required by the
process.
Maintenance and installation of the plate heat exchanger shall be done by
persons who have knowledge and authorization according to local regulations.
This may include actions such as piping, welding and other kind of
maintenance.
For maintenance actions not described in this manual, contact your Alfa Laval
representative for advice.

regulations. If there is any uncertainty regarding what material a component is
made of, contact the local Alfa Laval sales company. Use a certified (ISO
14001 or similar) scrapping or waste handling company.
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

Main components
1. Frame plate
Fixed plate with a various number of portholes for the connection of the
piping system. The carrying and guiding bar are attached to the frame
plate.
2. Carrying bar
Carries the plate pack and the pressure plate
3. Plate pack
Heat is transferred from one media to the other through the plates. The
plate pack consists of channel plates, end plates, gaskets and in some
cases transition plates.
4. Pressure plate
Moveable plate that compress the plate pack against the frame plate.
5. Guiding bar
Keeps the channel plates and the pressure plate aligned at their lower end
6. Support column
Supports carrying and guiding bars.
For T6 and T10 plate heat exchanger models a support foot is used
instead of support column.
7. Tightening bolts
Compress the plate pack between the frame plate and the pressure plate.
There are usually four tightening bolts used, in some cases six, these are
used to open and close the plate heat exchanger.
Remaining bolts are used as locking bolts.
8. Portholes
Portholes through the frame plate allow the media to enter into or exit from
the plate heat exchanger.

the foundation.
•Protection sheets
Cover the plate pack and protect against leakage of hot or aggressive fluids
and the hot plate pack.

3.2 Name plate
The type of unit, manufacturing number and manufacturing year can be found
on the name plate. Pressure vessel details in accordance with the applicable
pressure vessel code are also given. The name plate is fixed to the frame
plate, most commonly, or the pressure plate. The name plate can be a steel
plate or a sticker label.
WARNING Risk of damage to equipment.
The design pressures and temperatures for each unit are marked on the name
plate. These must not be exceeded.
CAUTION Risk of damage to equipment.
Avoid aggressive chemicals for cleaning the plate heat exchanger when a sticker
label is used.
The design pressure (11) and the design temperature (10), as given on the
name plate, are the values against which the plate heat exchanger is
approved according to the pressure vessel code in question. The design
temperature (10) may exceed the maximum operating temperature (8) for
which the gaskets have been selected for. If the operating temperatures as
specified on the PHE drawing are to be changed the supplier should be
consulted.

3.4 Function
The plate heat exchanger consists of a pack of corrugated metal plates with
portholes for the input and output of the two separate fluids. The heat transfer
between the two fluids takes place through the plates.
The plate pack is assembled between a frame plate and a pressure plate and
compressed by tightening bolts. The plates are fitted with a gasket which seals
the channel and directs the fluids into alternate channels. The plate
corrugation promotes fluid turbulence and supports the plates against
differential pressure.
