New from Alfa Laval, the T45 Plate
Heat Exchanger has a maximum heat
transfer surface of 2360m2 and
throughput of up to 1000kg/s. It is
intended for general heating and
cooling duties in process industries
and on offshore oil and gas structures.

In common with other Alfa Laval
gasketted Plate Heat Exchangers, the
T45 consists of a pack of corrugated
metal plates with port holes 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. Gaskets, available in
a range of materials, are used to seal
the inter-plate channels and direct the
fluid into alternate channels.
The number of plates is
determined by the flow rate, physical
properties of the fluids, pressure drop
and temperature programme. Since
the design is essentially modular, the
T45’s capacity can be increased or
reduced simply by adding or subtracting
the appropriate number of plates.
