General information
AlfaNova is a completely new type of plate heat exchanger (PHE), the
world's first PHE made of 100% stainless steel. It is based on Alfa
Laval's new revolutionary technology, Alfa Fusion, the art of joining
stainless steel components.
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
environmentally 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
- Desuper heater
- Absorptionsystems
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.
