Environmental Product DeclarationPlate heat exchanger
Flow principle o a plate heat exchanger
Ala Laval endeavours to perorm its own operations as
cleanly and eciently as possible, and to take environmental
aspects into consideration when developing, designing,
manuacturing, servicing and marketing its products. It does
this by identiying the signicant environmental impacts o its
products and operations and taking appropriate measures
to reduce them. This work is supported by implementingenvironmental management systems (normally certied to
ISO 14001) in all its manuacturing operations.
This Environmental Product Declaration is made in accordance
with ISO 14021. For more inormation, Lie Cycle Assessment
and Sustainability Reports are available on request.
The product
A plate heat exchanger consists o a pack o corrugated metal
plates. Each plate is tted with a rubber gasket, which seals
the channel ormed between two adjacent plates. In an alter-
native design, every second gasket is replaced by a laser-weldto allow or fuids aggressive to the gaskets. The plate pack
is assembled between a xed rame plate and a movable
pressure plate and compressed by tightening bolts. The rame
plate and the pressure plate are suspended rom an upper
carrying bar and guided by a lower guiding bar, both o which
are xed to a support column.
The size o the unit and the material and number o plates are
determined by the requirements o the particular application
and duty. Each individual plate heat exchanger is optimised
or its duty and, as a result, the usage o materials is kept to a
minimum.
Construction materials
Plate materials
The most commonly used plate material is stainless steel type
316, which accounts or about 80-85% o the volume. Other
materials used include highly alloyed stainless steel, titanium,
nickel and nickel-based alloys. The degree o recycled material
in stainless steel 316 is typically between 60-90%.
Rubber gasket materials
The most commonly used rubber gasket materials are nitrile
and EPDM. Other gasket materials used include FKM-type o
materials and PTFE.
Frame components materials
The rame and pressure plate are normally made o carbon
steel. Other rame components are made o aluminium, chro-mium steel and various types o stainless steel. The degree o
recycled material in carbon steel varies between suppliers.

Packing
Packing material consists o wood, plastics, cardboard boxes
and, in some cases, metal straps. Ala Laval enorces strict
environmental demands on suppliers or all types o packing
material.
Paint
The rames are painted using a water based two-component
polyamide cured epoxy coating pigmented with zinc phosphate.
The coating thickness depends on the corrosiveness o the
environment and is applied in accordance with ISO 12944-2.
Restricted substances
All components are checked against EU legislation and global
agreements such as the Montreal Protocol and the REACH
Candidate List. No components contain any substances on
those lists.
Manuacturing
The major environmental impact during manuacturing comes
rom the construction materials. Energy (electrical, ossil uels)
typically accounts or less than 3% o the total environmental
impact o manuacturing.
All Ala Laval’s manuacturing sites operate with an environ-
mental management system. Data on energy consumption
and emissions to air and water and other environmental actors
are reported annually in Ala Laval’s Sustainability Report.
Use
The heat exchanger as such does not give rise to any emis-
sions and does not consume any energy. To create a pressure
drop – the driving orce or heat transer – across the heat
exchanger, external pumps are normally needed.
During the lietime o the heat exchanger, there may be the
need or the replacement o parts such as gaskets and plates.
In order to maintain the level o perormance, Ala Laval
recommends cleaning at regular intervals, o which the re-
quency depends on application and duty. Ala Laval provides
non-toxic cleaning chemicals containing biodegradable
suractants.
Transportation
Transportation accounts or a large part o Ala Laval’s CO2
emissions. In order to reduce these emissions, all transportation
providers are evaluated and classied rom an environmental
point o view. Furthermore, strict demands are placed on
transportation providers to propose ideas or reducing the
environmental impact o Ala Laval’s transportation.
End o lie
Dismantling instructions are provided in the user manual. The
unit is readily disassembled into its main components. Waste
o the product is not hazardous (EU Directive 91/689/EEC).
Chemicals must be drained o beore any end o lie treatment
and treated according to local regulations.
Recycling o metals
It is possible to recycle all metallic material, thus reducing the
use o virgin material or the new production o metals. Plates
are sorted according to type o material and rame components
are sorted as mixed scrap.
Incineration/Landfll o gaskets
Rubber gaskets can either be sent or incineration, thus
recovering energy, or be used as landll depending on the
local directives o the country in which the unit has been used.
Packing
Wood and cardboard boxes can be reused, recycled or used
or energy recovery. Plastics should be recycled or incinerated
at a licenced incineration plant. Metal straps should be sent
or material recycling.
Ala Laval endeavours to perorm its own operations as cleanly and
eciently as possible, and to take environmental aspects into con-
sideration when developing, designing, manuacturing, servicing and
marketing its products.
