PNEUDRI - How It Works
Adsorption dryers work on the principle of moisture always
migrating to the driest medium possible. Therefore, water
vapour is removed from compressed air by passing it over
an adsorbent desiccant material.

As the air contacts the adsorbent material, water vapour off-line, being regenerated or is re-pressurised, ready to come
transfers from the wet air to the dry desiccant, however, on-line. All adsorption dryers remove water in this manner.
adsorbent materials have a fixed adsorption capacity and once
this capacity is reached, they must be regenerated or replaced. The energy consumed by an adsorption dryer can be directly
attributed to the method used to regenerate the adsorbent
Therefore, to provide a continuous supply of clean, dry material. Parker domnick hunter PNEUDRI dryers utilise either

on-line, drying the incoming compressed air, the other is either

PNEUDRI Operation - Drying Cycle

Dry Air
The process air enters the dryer through the inlet and is
directed into the on-line drying chamber via the inlet valves
and lower manifold.
(PNEUDRI models can be made up of either single or multiple Desiccant
drying columns, depending upon the range) Bead

The air is evenly distributed through the drying columns and

passes over the desiccant material, reducing the water vapour
content. Wet
Air
The dried process air then combines in the upper manifold
and exits the dryer via the outlet check valves.

Column Changeover
Before the on-line (drying) and off -line
(regenerating) columns change over, the dryer
exhaust valve, is closed, allowing the purge air to
re-pressurise the off -line columns. This ensures a
consistent system pressure and dewpoint when the
drying chambers change over.

PNEUDRI Operation - Regeneration Cycle

Dry Purge
(Heatless PSA or Pressure Swing Adsorption) Air

At the start of the regeneration cycle, the exhaust valve of the dryer is closed
and the off-line chamber is at full line pressure. The air in the off-line chamber
has a dewpoint equal to the air leaving the dryer. Desiccant
Bead
The exhaust valve is then opened and the dry air within the chamber expands
rapidly as it leaves the dryer via the exhaust silencer, forcing water to be
removed from the desiccant material.
Once the off-line chamber has de-pressurised, a continuous bleed of dried Wet Purge
process air is directed into the off-line upper manifold. This air is known Air to
Atmosphere
as purge air.
With the exhaust valve open, the purge air expands from line pressure
to atmospheric pressure and flows downwards through the columns,
over the off-line desiccant material. Standard Drying / Regeneration Cycle

 PNEUDRI - The world's most advanced
modular drying system
With the proven benefit of advanced aluminium forming
technology, Parker domnick hunter has developed a twin tower
desiccant dryer that is typically 60% of the size and weight of
conventional designs.

These advanced desiccant dryers include ranges of heatless and eliminates the need for complex valves or interconnecting
heat-regenerative PNEUDRI dryers which provide one of the piping.

PNEUDRI - four key features
guarantee air quality
OIL-X EVOLUTION filtration
Adsorption dryers are designed for the removal of water vapour and not liquid water, water
aerosols, oil, particulates or micro-organisms. Only by using Parker domnick hunter OIL-X
EVOLUTION pre and after filtration can the removal of these contaminants be assured and air
quality in accordance with all editions of ISO8573-1 be guaranteed.

Modular aluminium design

Aluminium extrusions are used throughout for drying
chambers and distribution manifolds. This design allows
the desiccant material to be retained within the drying
chambers.'Snowstorm' filling, prevents movement of the
desiccant material during operation and also eliminates
desiccant attrition and breakdown which could lead to a
loss of pressure dewpoint.

Adsorbent desiccant material

Specially selected desiccant materials provide:
• Optimum adsorption and regeneration capacity - to ensure consistent dewpoint
• Low dusting - to prevent blockage of downstream filtration
• High crush strength - to prevent breakdown of the desiccant during operation
• High resistance to aggressive and oil-free condensate - for compatibility
with all types of air compressor, their lubricants and condensate

Snowstorm filled bed

'Snowstorm' filling method
Unique to Parker domnick hunter modular dryers is the
snowstorm filling technique used to charge the drying
chambers with adsorbent desiccant material.
The benefits are:

• Achieves maximum packing density for the

desiccant material, fully utilising all of the available
space envelope

• Prevents air channelling through the desiccant

as experienced with twin tower designs. Due
to channelling, twin tower designs require more

Loose filled bed
• Prevents desiccant attrition which can lead
to dusting, blocked filters and loss of dewpoint

• Allows 100% of the available desiccant material to

be used for drying, therefore reducing the amount
of desiccant required and maintenance costs

• 100% of the desiccant is regenerated ensuring

 Selecting the right dryer for
your compressed air system
To achieve the degree of air quality specified by ISO8573-1:2010,
a careful approach to system design, commissioning and
operation must be adopted.
Parker domnick hunter recommends that compressed air is treated:
• Prior to entry into the distribution system
• At critical usage points and applications
This ensures that contamination already in the distribution system is removed.

Purification equipment should be installed where the air is at the lowest possible
temperature (i.e. downstream of after-coolers and air receivers). Point-of-use
purification equipment should be installed as close as possible to the application.

What size PNEUDRI do I require?
Dryer Selection
To correctly select a dryer model, the flow rate of the dryer must be adjusted for the minimum operating pressure and
maximum operational temperature of the system. If the dewpoint required is different to the standard dewpoint of the
dryer then the flow rate must also be adjusted for the required outlet dewpoint.

Selection Example
Selecting a dryer for a compressor producing at full load 1500 m³/hr at 8.3 bar g with 38°C air inlet temperature and a pressure
dewpoint of -40°C.

 Improving manufacturing efficiency
Every manufacturing organisation strives to improve its
operational efficiency, especially in terms of energy consumption
and environmental impact.

Heatless adsorption dryers use clean, dry process air for regeneration,
but in real terms, this means that not all of the compressed air generated
is available for manufacturing processes.
Generating compressed air uses electrical energy, type of dryer may be higher when compared to
so although heatless adsorption dryers have many other types of adsorption dryers with different
benefits, the energy costs associated with this regeneration methods.

INTRODUCING

 Saving energy with the dewpoint dependent

of low demand. Daily and seasonal fluctuations in ambient energy (purge air) is consumed than is actually necessary.
temperature and humidity also change the moisture loading
placed upon the dryer.

Dewpoint Dependent Switching (DDS) Energy Management System

With the DDS Energy Management system installed, the drying cycle remains unchanged, however as the drying chambers are
about to change, the DDS system overrides normal operation to fully utilise the drying capacity of the on-line desiccant material.

DDS operation
At column changeover, the exhaust valve is closed to allow the
purge air to re-pressurise the off-line column, thus ensuring no
loss of system pressure.
At this time, both drying chambers are at full line pressure, so
that no purge air is being used and the dryer is in a state of zero
energy consumption.
Under normal operation, the drying chambers would proceed
to change over automatically, however the DDS energy
management system incorporates a hygrometer which is used
to monitor the pressure dewpoint of the air leaving the dryer. If
the air is drier than the pre-set dewpoint, the desiccant material
is only partially saturated and has drying capacity remaining
within it, therefore change over is delayed.
The hygrometer constantly monitors the outlet dewpoint until
the pre-set level has been achieved, at which point, change over
will occur.
The drying and regenerating cycle will then continue normally
until the end of the next column changeover when the DDS
energy management system may again extend the drying period
as dictated by the outlet air quality.
