How
do
desiccant
dryers
work?
Desiccant
dryers
consist
of
two
towers
filled
with
desiccant.
Wet
compressed
air
passes
directly
through
the
substance,
which
adsorbs
the
moisture.
The
desiccant
has
a
finite
adsorption
capacity
before
it
must
be
dried
out.
Hence
the
twin
tower
design.
While
one
tower
is
drying
air,
the
other
is
being
regenerated.
Atlas offers two types of desiccant dryers, the BD+ rangeof blower (zero) purge dryers and the CD(+) series of heatless desiccant dryers. The difference lies in their regeneration process.
1.
Drying
Wet
compressed
air
flows
upward
through
the
adsorbent
desiccant
from
bottom
to
top
(1).
2.
Regeneration
Heatless
desiccant
dryers
–
CD+:
Dry
air
from
the
drying
tower
outlet
is
expanded
to
atmospheric
pressure
and
sent
through
the
saturated
desiccant,
forcing
the
adsorbed
moisture
out
(2
and
4).
After
desorption,
the
blow-off
valve
is
closed
and
the
vessel
is
re-pressurized.
Blower
(zero)
purge
desiccant
dryers
–
BD+:
The
blower
(5)
takes
ambient
air
and
blows
it
across
the
external
heater
(6).
The
heated
air
is
then
sent
through
the
saturated
desiccant
(2),
forcing
the
adsorbed
moisture
out.
3.
Cooling
(BD+)
BD+
with
purge:
After
the
heating
phase,
the
desiccant
is
cooled
by
expanding
dry
compressed
air
from
the
outlet
of
the
adsorbing
vessel
over
the
hot
reactivated
tower.
BD+
with
zero
purge:
After
the
heating
phase,
the
blower
takes
in
ambient
air
and
sends
it
through
the
reactivated
tower
from
bottom
to
top.
4.
Switching
After
regeneration,
drying
switches
from
the
saturated
tower
to
the
regenerated
tower
(3).

Premium
performance&
cost-efficiency
1 Quality desiccant
•
High
adsorption
silica
gel
desiccant
needs
less
reactivation
energy
than
other
drying
agents.
•
Dual-layer
desiccant
bed
with
a
water-resistant
bottom
layer
protects
the
high-performance
top
layer.
•
Pressure
dew
point
of
-40°C/-40°F
as
standard
(-70°C/-100°F
optional).
•
Up
to
30%
extra
desiccant
to
deliver
consistent
performance
even
in
harsh
conditions
such
as
high
temperatures
and
temporary
overloads.
2
Stainless
steel
valves
High-performance
stainless
steel
butterfly
valves
with
actuators
ensure
a
long
lifetime.
3
Low
wattage
density
heater
•
Stainless
steel
design
extends
lifetime.
•
Heater
is
installed
in
an
insulated
pipe
for
an
energy-efficient
set-up.
•
Insulated
vessels
are
available
as
an
option
to
further
reduce
heat
losses
and
increase
overall
efficiency(standard
on
the
-70
°C/-100
°F
model).
4
Galvanized
piping
with
flanged
connections
•
Flanged
piping
simplifies
maintenance
and
minimizes
the
risk
of
leaks.
•
Pipe
sizing
is
optimized
to
ensure
a
low
pressure
drop
for
maximum
energy
savings.
5
Filters
•
A
pre-filter
prevents
oil
contamination
to
increase
desiccant
lifetime.
•
An
after-filter
protects
the
airnet
from
desiccant
dust
and
network
contamination.
•
Can
be
mounted
directly
on
the
inlet
and
outlet
of
the
dryer
for
low
pressure
drop.
•
Easy
to
assemble
and
maintain.
No
extra
piping
and
filter
connections
are
required.
6
Advanced
controland
monitoring
system
•
Fitted
inside
an
IP54
cubicle
for
easy
cabling
and
safety.
•
Monitors
all
parameters
to
ensure
maximum
reliability.
7
Dew
Point
Dependent
Switching
•
Real
pressure
dew
point
monitoring
(hygrometer).
•
Pressure
dew
point
(and
alarm).
•
The
dryer
will
only
switch
to
the
next
tower
when
the
desiccant
is
saturated,
as
measured
by
the
dew
point
sensor.
During
this
cycle
time
extension,
the
dryer
consumes
no
purge
air,
resulting
in
a
significant
reduction
in
energy
use.
8
Robust
and
compact
design
•
Standard
frame,
including
forklift
slots
and
lifting
eyes
for
easy
handling.
•
Wide
vessels
ensure
a
low
air
speed
and
a
longer
contact
time.
•
Flanges
connecting
the
vessels
are
integrated
into
the
top
and
bottom
shells,
lowering
the
total
unit
height.
