General information
NL series is a plate heat exchanger made of stainless steel and Nickel. Nickel heat exchangers are well suited
in applications which put high demand on cleanliness, applications where ammonia is used.
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.
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.
