A NEW GENERATION OF COLD DRYERS
BY SCHNEIDER DRUCKLUFT
ULTRA-EFFICIENT
COMPRESSED AIR PROCESSING
ALL UNDER ONE ROOF!
To make highqualitycompressed
air available at
the workplace it
needs to be properly
processed.
This expands the
life cycle of your
pneumatic tools,
saves high maintenance
costs and is
good for the health
of your staff and
the environment.
The advantages
gained through
this are discussed
in this information!

A NEW GENERATION OF
COLD DRYERS BY
SCHNEIDER DRUCKLUFT
Technical advantages
at a glance.
◆ Long life cycle for pneumatic
tools, pneumatic controls...due
to air that is dried
fully automatic.
◆ Compact casing - allowing
space-saving, suspension
assembly
◆ Cooling module made
entirely of stainless steel
l unsurpassed effective
cooling
l absolutely rust-proof
l permanently smooth
surfaces provide an
even flow profile
◆ No pre-filter required
◆ The vertical air conduction
without deflections containing
a profile that forms dropwise
condensation guarantees
handy self-cleaning.
◆ The low speed eliminator
is situated at the lowest point
exploiting gravity.
The result: Almost 100% effectiveness!
◆ The automatic condensation
discharge (DK 800 PT and
over) operates with the help of
an independent monitoring
function. This prevents loss of
compressed air
◆ ESA Energy Saver
Automat:
flexible dew point control and
shut-down for partial load
◆ Electronic monitoring via
light-emitting diodes.
Potential-free error messages
◆ Electric connection 230
V/50 Hz
The new cold dryer comprises
the following effective components:
pre-cooler, cooler and
mist eliminator.
A compact convincing
package.

Why is the newly-developed heat
exchanger and separating system
so efficient?
◆ Automatic shut-off in the
off-load and partial load sector
Energy costs drop by up to
80%!
◆ During intermittent duty
the pressure dew point is kept
within class 4 and 5 as per ISO
8573.1
New: Utmost efficiency in energy
consumption - provided by a new
heat exchanger made of stainless
steel plates.
◆ Stainless steel prevents
the occurrence of corrosion
and oxidation.
◆ Large heat exchanger
surfaces occupying the smallest
possible space provide an
even flow profile and ultimate
cooling performance (extremely
high cold storage capacity)
◆ Optimal transport of
liquid and solid matter is achieved
by vertical air conduction.
This principle has definite
advantages: it is self-cleaning,
does not build up dirt and guarantees
permanently smooth
surfaces
◆ The plate profile forms
large, easily eliminated drops
of condensation.
Why does the innovative energy
saver unit ESA work so efficiently?
◆ When running in partial
load operation the ESA saves
precious energy due to the
automatic shut-down of the
refrigeration compressor
◆ ESA acquires all parameters
relevant for operation and
controls the dryer electronically.
◆ Genuine cold storage - in
the form of liquid refrigerant -
keeps the number of switching
actuations down.
Additional pros of the new cold
dryer generation...
◆ The well arranged, easy
to operate control board
◆ The futuristic casing
design: compact, spacesaving,
robust
Choosing innovative technology
helps you save!
The core of the new
generation dryers
provided by
Schneider-Druckluft
is a newly developed
heat exchanger
made of stainless
steel plates

Technical Data of New Generation Cold Dryers
Plates that separate
the air flow and safeguard
the cycle
Refrigerant
1 ] Moist, warm,
impure compressed
air flows in to be cooled
by cold air.
2 ] The compressed
air is separated inside
the new type of
low speed separator
from the condensate
with almost 100%
effectiveness.
3 ] Afterwards the
condensate is drained
from the system.
