Application
Pasteurization and general cooling/heating of dairy and brewery
products, fruit juices and similar food products.
Working principle
The heat exchanger consists of a number of corrugated plates
clamped together in a frame and sealed at the edges by means of
gaskets.
The plates have ports at the corners and the gaskets are so arranged
that the two media flow through alternate passages between the
plates. The two media are separated by the plates and cannot be
mixed. Heat is transferred through the plates, from the hot medium
to the cold.
One unit can contain several heat exchangers, separated by
connection plates with interchangeable connections.
Frame
The frame consists of a fixed frame plate, a movable pressure plate,
an upper carrying bar, a lower guiding bar, a support column and
tightening bolts with nuts.
The Clip 3-RM frame plate has adjustable feet and the Clip 3-RMV
is without feet for wall mounting.
Plate
The corrugation of the plates provides a passage between the plates,
supports each plate against the adjacent one and enhances the
turbulence, resulting inefficient heat transfer.
The plates have a chevron pattern for maximum strength at high
working pressures.
The plates are reversible and have parallel flow, which means only
one type of plate is needed.
Gasket
The plates are supplied with glue-free Clip-On gaskets, which are easy
to replace even with the plates still hanging in the frame.
No tools are needed to replace the gaskets.
