Fusion plate heat exchanger AlfaNova 14 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 - Economizer - Desuperheater - Absorption systems Other main applications: - Domestic hot water heater - Process cooling - Hydraulic oil cooling - Laser cooling - Hygienic/sanitary application - 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 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.
