products
• Heating/cooling in the pharmaceutical industry.
Standard design
Frame
The plates and the pressure plate are suspended from an upper
carrying bar and located by a lower guiding bar, both of which are
fixed to the support column. The tightening bolts are equipped with
ball bearing washers in order to facilitate opening and closing of the
unit. The frame and support column have adjustable feet.
One unit may contain several heat exchangers, separated by
connection plates with interchangeable connections.
The Front plate
The Front plates are designed to meet the highest requirements in
food processing. The combination of high pressing depth and a
pattern with relatively few contact points provides longer operation
time without interruptions. The distribution pattern assures an even
flow over the entire plate. The ports have a diameter enabling cleaning
in place (CIP) with the same flow used in the process itself.
The plate pack
The chevron corrugation of the plates provides a passage between
the plates and supports each plate against the adjacent one. It also
enhances the turbulence, resulting in efficient heat transfer.
Different chevron angles are available to reach the optimal high heat
transfer at a given pressure drop. A unique distribution area provides
an efficient flow over the plate surface. The Alfa Laval hanging system
enables easy handling of the plates in the frame. Furthermore the
corner guiding provides a strong plate pack. The plates are reversible
and have parallel flow, which means that only one type of gasket
is needed.
Working principle
A Plate Heat Exchanger consists of a pack of corrugated metal plates
with port holes for the passage of two fluids between which heat
transfer will take place.
The plate pack is assembled between a fixed frame plate and a
movable pressure plate and compressed by tightening bolts.
The plates are fitted with a gasket which seals the inter-plate channel
and directs the fluids into alternate channels. The number of plates is
determined by the flow rate, physical properties of the fluids and the
temperature program. Connections may be located in frame plate
and pressure plate.
