Fusion plate heat exchanger
AlfaNova 52 / AlfaNova HP 52
General information
AlfaNova is a plate heat exchanger 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
Within refrigeration:
- Oil cooler
- Condenser
- Evaporator
- Economizer
- Desuperheater
- Absorption systems
Other main applications:
- Domestic hot water heater
- Process cooling
- Hydraulic oil cooling
- Laser cooling
- Hygienic/sanitary
- Water/water 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, always in
counter-current 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.
