ations as cleanly and efficiently as possible,
and to take environmental aspects into con-
siderattion when developing, designing, manu-
facturing, servicing and marketing its
products.
Unpacking
Packing material consists of wood, plastics, card-
board 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
During maintenance oil and wear parts in the ma-
chine are replaced.
• All metal parts should be sent for material recy-
cling.
• Worn out or defective electronic parts should
be sent to a licensed handler for material recy-
cling.
• Oil and all non metal wear parts must be taken
care of in agreement with local regulations.
Scrapping
At end of use, the equipment shall be recycleed
according to relevant, local regulations. Beside the
equipmnet itself, any hazardous residues from the
process liquid must be considered and dealt with in
a proper manner. When in doubt, or in absence of
local regulations, please contact the local Alfa
Laval sales company.

Function
The fusion plate heat exchangers consist of a pack of
bonded corrugated metal plates with ports for the
passage of the two fluids between which heat trans-
fer will take place.
The media in the heat transfer are led into the bond-
ed plate pack through portholes at the corners and
are distributed into the passages between the bond-
ed, corrugated plates.
The heating surface consists of thin corrugated
plates stacked on top of each other. In the fusion
process at high temperature channels are formed
between the plates and corner ports are arranged
so that the two media flow through alternate chan-
nels, always in counter-current flow. The contact
points are also bonded to withstand the pressure
of the media handled.
The fusion plate heat exchanger is typically
used for heating or cooling media with low to
medium viscosity. A specific fusion plate heat
exchanger is dimensioned for a specific duty,
set out in the product documentation, and
should not be used in any other way without
consulting the supplier.
Bonded seal
Keeping the media
within the unit.
Bonded corrugated
plates for media flow in
alternate channels.
Cover plates
Front and rear cover plates to
protect the channel plates and
increase the design pressure.

AlfaFusion technology
Fusion-bonded plate heat exchangers represent a
new class of plate heat exchangers made of
100 % stainless steel.
AlfaNova comprises a number of thin corrugated
stainless steel plates. The process uses a stain-
less steel filler as activator to bond the plates to-
gether in a high temperature furnace. At contact
points between the corrugated plates the filler re-
acts with the plate surface. The filler has a very
good capability to wet surfaces and fill crevices.
It has almost full interaction with the plates and a fu-
sion zone is created. This zone is in consequence
also of stainless steel and has similar properties to
the plates in terms of corrosion resistance and dura-
bility.
AlfaFusion technology enables the production of reli-
able heat plate exchangers with higher mechanical
and termal resistance than those of conventional
technology.
