Fusion plate heat exchanger
AlfaNova 400 / AlfaNova HP 400
General information
AlfaNova plate heat exchangers are made of 100% stainless
steel. It is based on Alfa Laval’s new revolutionary technology,
AlfaFusion, the art of joining stainless steel components
together.
AlfaNova heat exchangers are well suited in applications
which put high demand on cleanliness, applications where
ammonia is used or applications where copper or nickel
contamination is not accepted. Its high resistance to corrosion
makes it both hygienic and environmental friendly.
It is extremely compact compared to its capacity to withstand
great strains in demanding heat transfer applications.
Applications
– Evaporators
– Economizers
– Absorption systems
– Process cooling/heating
Working principles
The heating surface consists of thin corrugated metal plates
stacked on top of each other. Channels are formed between
the plates and corner ports are arranged so that the two
media flow through alternate channels, normally in countercurrent
flow. The media are kept in the unit by a bonded
seal around the edge of the plates. The contact points of the
plates are also bonded to withstand the pressure of the media
handled.
Standard design
The plate pack is covered by cover plates. Connections are
located in the front or rear cover plate. The channel plates are
corrugated to improve heat transfer design.
