Cooling and heating of dairy, brewery, beverage and viscous products
and pasteurization in some applications.
Working principle
The plate heat exchanger consists of a pack of corrugated metal
plates with portholes for the passage of two fluids between which
heat transfer will take place.
The plate pack is assembled between a frame plate and a pressure
plate and compressed by tightening bolts.
The plates are fitted with a gasket which seals the channel and directs
the fluids into alternate channels. The number of plates are determined
by the flow rate, physical properties of the fluids, pressure drop and
temperature program. The plate corrugations promote fluid turbulence
and support the plates against differential pressure.
The plates and the pressure plate are located by an upper bar and
a lower bar, both of which are fixed to the support column. On the
largest type some tightening bolts are equipped with ball bearing
washers in order to facilitate opening and closing of the unit. The frame
is designed for mounting on a floor only. Standard feet are fixed.
One unit can contain several sections, separated by connection plates
with interchangeable connections. (Not valid for M3-Base).
The corrugation of the plates provides a passage between the plates,
supports each plate against the adjacent one and enhances the
turbulence, resulting in efficient heat transfer. Corner ports and gaskets
are arranged so that the two media flow through alternate channels.
The plates have a chevron pattern for maximum strength at high
working pressures. Different chevron designs are available, in order to
obtain optimal high heat transfer and low pressure drop.
A unique distribution area provides an even flow over the plate surface.
The plates are reversible and have parallel flow, which means only
one type of plate is needed.

Flow principle of a plate heat exchanger
The plates are supplied with glue-free Clip-On gaskets, which are easy
to replace even with the plates still standing in the frame.
