FrontLine™ - Gemini Plate Heat Exchangers
Gemini plate
.
Application
Pasteurization and general cooling/heating of dairy, brewery,
beverage and food products, when a mixproof design is required.
Also applicable for cooling/heating in the pharmaceutical industry.
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 and if
multi section PHE, also in connection plate
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 Gemini plate
The Gemini plates consist of two sheets formed together in order to
minimize the inter-sheet air gap reducing the heat transfer.
The gap between the two sheets is in direct contact with the
atmosphere and is not in contact with any of the liquids. In order not
to trap any liquid between the two sheets, contact to the atmosphere
is safeguarded around the whole periphery of the plate.
The Gemini double wall plates will increase the production safety, as a
crack in a plate do not result in mixing of the two media.
