WHY DRYING?
DEFINITIONS
Referring to water (in the form of humidity), plastic
polymers have the capacity:
H 2O
H 2O
H 2O
- to collect it only on their surface :
 non-hygroscopic materials
H 2O
H 2O
H 2O
H 2O
PVC, PE, PP, PS, POM homopolymer
H2O
- to absorb it within their molecular structure:
 hygroscopic materials
PET, PEN, PBT, PETG, PC, PA, PMMA,
POM copolymer, SAN, ABS, PUR, PEM,
PEEK, PPS, PPO, PI, EVOH, etc.

AIR PROPERTIES
DEW POINT
It is the temperature at which water vapor starts condense
(as liquid) on a surface at that temperature.
It represents the temperature at which the specified air
would reach the saturation limit.
Practically determines the water content contained in the air
(see previous table)
Lower is the dew point, lower is the water content in the air
WHY DRYING?
HUMIDITY EFFECTS
RESIN NOT DRIED DURING THE PROCESS 
WATER AT HIGH TEMPERATURE AND PRESSURE 
OVERHEATED STEAM AT HIGH PRESSURE WITHIN
MACROMOLECULES 
BREAKING OF THE MOLECULAR CHAINS 
considerable reduction of the mechanical and electrical
features, superficial finish, aesthetical aspect, etc.
Productivity decrease  production costs
increase due to higher scraps
WHY DRYING?
HUMIDITY EFFECTS
Humidity presence in the granules is possible
cause of visible defects in the final product
BUBBLES, VOIDS,
INCOMPLETE PIECES
BURNINGS
FLASHES
HAZINESS
DIMENSIONIONAL DEFECTS,
UNCONSISTANT SHRINKAGE
STREAKS, SPOTS

WHY DRYING?
POLYMERS DEHUMIDIFICATION
The procedure of moving water
molecules from inside the
granules to the outside surface,
where they are stripped away by
flowing means
The engine of the process is the
difference of partial vapor
pressure between the contained
moisture inside the pellets and the
surrounding air.

NOTES:
[1] Dried material to be handled very carefully
[2] Toxic flying components when drying; required flying component condensator
[3] Longer residence time may cause oxidation and/or degradation
[4] Maximum drying temperature is 67°C, higher temperature degrades the material. After cooler 'MT' required
[5] Soft PUR may bridge in the hopper
[6] High air-flow required
[7] Very high flow required
[8] The material generally does not degrade
[9] Maximum drying temperature is 45°C. Special post cooler required

“WD & WDS” DRYERS
MAIN FEATURES
• Frame with modern design and self-centering side
panels with spring lock
• Latest-generation electronic card with LCD display
• Automatic operation with daily/weekly timer
• “Energy” function: 3 prefixed sets of working dew point
(approx -50°C, -40°C, -30°C)
• Automatic “RCE” function to reduce process air
temperature when material throughput decreases or
machine stops. This function can operate in combination
with anti-stress valves (ATR system, optional)
• Static relays for the electrical heaters operation
“WD & WDS” DRYERS
MAIN FEATURES
• Wheel fitted with molecular sieve spread on a honeycomb
matrix where air passes through, driven by chain for
constant and controlled rotation
• Side channel blower with high pressure and constant
airflow in the hopper with wide surface air cartridge filter
• Very compact dimensions but with large internal spaces
for optimal maintenance
• Heat recovery exchangers with triple cross for maximum
energy saving (TRIFLUX system)
• Control card with hopper loader operation check
integrated with the RCE function
“WD & WDS” DRYERS
MAIN FEATURES
• MT version with operation from +70°C up to 140°C without
need of cooling water by using the air/air heat recovery
exchanger TRIFLUX by New Omap exclusive design
• HT version up to 190°C with water/air heat exchanger fitted
with temperature-controlled solenoid valve for water
interception to reduce unnecessary water-flow
• All dryer components are electrically operated: no need
of compressed air
• No need to replace molecular sieves after the usual
timing of twin-towers systems. Reduced
maintenance

Benefits of New Omap WDS Dryer
1.
New Omap dryer uses half of the Energy against the Motan and due to the improved design allows a reduction in drying
time.
2.
The material is also being dried to the recommended moisture content levels which is a facility we currently do not have for
engineering materials. The Industrial guard should be running with a minimum 75 kgs dryer.
3.
The dryer can be used on small throughput jobs which will not degrade the material as a result of the RCE function.
4.
The RCE function, once activated can reduce the power consumption down to 0.9 kW/hr.
5.
The dryer does not require compressed air.
6.
An electronic timer is built into the dryer enabling the drying operation to commence on a Monday morning rather than being
started manually.

NEW DEVELOPMENTS
Compact Honeycomb Dryer:
New Omap is developing a new series of
compact honeycomb dryers, WDA series,
that will be used for small capacities, where
the dryer will be fixed directly on the hopper
structure.
The units will be fitted on hoppers range of
30-100 litres and it has been designed to
perform process airflow ranging from 10 to 30
m3/h
The project is foreseen to be completed by
end of year 2014

COMPRESSED AIR
DRYERS
“AD-ADK” SERIES
NEW OMAP srl - Legnaro (PD) – December 2013, by Massimo Rubbis
“AD and ADK” DRYERS
TECHNOLOGY
The development of the first
compressed air dryers started at the
beginning of 90’s.
The idea to use compressed air for
drying, comes from the fact that
compressed air is present in each
plastic processing factory and it is also
already partially dried. Compressed air
when expanded at atmospheric
pressure results having a lower dew
point than when compressed. This
effect can be used to dry polymers.

EXPANSION
Compressed air is like a damp
sponge. When compressed, it
does condense moisture which is
then lost in the compression
phase.
By releasing (expanding) it, it
increases the ability to absorb
further moisture and compared to
the initial phase the amount of
moisture is greatly reduced.

ENERGY CONSUMPTION?
Energy cost to produce 1 m3/h of
compressed air.
This parameter depends on the
type of compressor used, with
inverter or not, with energy recovery
system, pipeline leaks and other
conditions. It is a great variability
which is not easy to evaluate.
In literature: values r​ anging 0.08 and
0.22 kWh/m3.
The lowest value for the latest
generation of compressed air
generating systems (sophisticated
solutions)
“AD and ADK” DRYERS
COMPARISON EXAMPLE OF ENERGY CONSUMPTION
Example:
Twin tower desiccant dryer DE20MT-55 (operating at an average of
-40°C dew point, airflow 80 m3/h): 1.72 kWh @ 80°C. Considering a
capacity of 7.5 kg/h PA  0.229 kW/kg
Compressed air dryer ADK50 (-50°C dew point, installed 1 kW):
assuming an average real value of 0.15 kWh/m3, max airflow 16
Nm3/h: 1.0 + 0.15/16 = 1.00938. Considering 7.5 kg/h PA  0.135
kW/kg.
It should be noted, however, the randomness assumption of the
cost of compressed air! It is emphasized, however, that the solution
is energetically advantageous for systems with hopper up to 50-100
liters.
“AD and ADK” DRYERS
COMPRESSED AIR DRYERS “AD/ADK” SERIES
Basic version AD:
• models with drying hoppers of 5, 15, 30, 50 dm3
• drying performances with dew point values from -20°C (value
depending on the performances of the compressed air system)
Version ADK by adding the “Extra Drying Kit”
• Same hopper sizes
• drying performances down to -50°C dew point
All versions are designed for installations directly on machine
throats and for small-medium throughputs.
“AD and ADK” DRYERS
COMPRESSED AIR DRYERS “AD/ADK” SERIES
The electronic control allows an
easy programming thanks to
the internal data-base of the
main materials, with the
possibility of free setting of the
data by the operator
“AD and ADK” DRYERS
COMPRESSED AIR DRYERS “AD/ADK” SERIES
The electronic control allows to
adjust the compressed air flow as
function of the hourly capacity and
type of material that, in
combination with the anti-stress
system reducing the thermal load,
automatically reduces the
consumption and therefore the
risks of thermo-oxidative
degradation.
