 AlfaCond
Plate Condenser
Looking for an alternative to convention shell and tube condensers?
Alfa Laval's AlfaCond, the world's first plate condenser, requires
less space, material, money and still provides higher heat transfer
efficiency.
AlfaCond is the world's first tailor-made plate condenser. It was
developed specifically for condensing vapours under low pressure/vacuum
conditions in evaporation and distillation systems. A whole range
of AlfaCond condensers is available to suit specific applications
and capacity requirements.
How It Works
AlfaCond is tailored for vacuum condensation. The vapour inlet connection
is very large whereas the two condensate outlets are small. The
cooling water connections are medium-sized and located in the centre
of the plate. AlfaCond consists of a plate pack with plates welded
together in pairs forming so-called cassettes. The cassette concept
gives rise to two different type of channels - welded channels used
for the condensing vapour and gasketed channels used for the cooling
water.
The plate pattern is specifically designed for optimal condensation,
with an asymmetric configuration that features a large gap on the
vapour side and a small gap on the cooling water side. This makes
it possible to maintain a very low pressure drop on the vapour side
while keeping up the velocity and turbulence on the water side.
This maximizes the heat transfer efficiency and minimizes fouling.
Why Choose AlfaCond?
Lower costs because the high heat transfer efficiency means
that much less heat transfer area is needed compared to a conventional
shelland-tube. This makes AlfaCond more cost effective, especially
if stainless steel or titanium is required. The compactness of the
design also saves space, which reduces transport, erection and installation
costs.
Less fouling on the cooling water side compared to shell-and-tube
condensers, due to the high turbulence created by the special design
of the corrugated plates.
Easy cleaning of the cooling water side using either mechanical
or chemical means.
Easy to increase capacity by just adding extra cassettes
in the existing frame.
Fully counter-current flow, which makes it possible to sub-cool
the non-condensable gases better than in a comparable shell-and-tube
installation. This reduces the load on the vacuum pump.
