Thermal Transfer Systems M3-VG - Manual

M3
Plate heat exchanger
Applications
General heating and cooling duties. Heating by means
of steam.
Standard design
The plate heat exchanger consists of a pack of corrugated
metal plates with portholes for the passage of the 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
interplate channel and directs the fluids into alternate channels.
The number of plates is 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 plate and the pressure plate are suspended from an
upper carrying bar and located by a lower guiding bar, both
of which are fixed to a support column.
Connections are located in the frame plate or, if either or both
fluids make more than a single pass within the unit, in the
frame and pressure plates.
Typical capacities
Liquid flow rate
Up to 60 GPM, depending on media, permitted pressure drop
and temperature program.
Water heating by steam
50 to 250 kW, 14 tons to 90 tons
