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.
