Product Details

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 brazed seal around the edge of the plates. The contact points of the plates are also brazed 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.
