consists of the models named XT and XL
The modular concept invented by Polacel and carried through in our product lines combines
efficiency in manufacturing with a broad spectrum of models and solutions for almost any cooling
demand. We pride ourselves in assisting our clients in the process of finding the best tower for the
job. Part of this is presenting the right information on the right time combined with the expertise of
our sales engineers. This catalogue is not intended to replace this procedure, but is composed as
part of the independently CTI thermal rating certification program.

The company now focuses on specialty mechanical engineering
– especially process engineering and equipment. GEA Group tech-
nologies are applied in the food, chemical and petrochemical in-
dustries, the energy sector, air treatment and shipbuilding as well
as the pharmaceutical and cosmetic industries. The GEA Group is
one of the world`s market and technology leaders in 90 per cent
of its businesses.
GEA is a solid foundation for the GEA Polacel activities and it pro-
vides us with greater scope. Good contacts with affiliated organiza-
tions that are leaders in our field provide an ongoing stimulus to
our own development. This is what makes GEA Polacel a leader in
the introduction of technological improvements.
GEA Polacel[Background]
GEA Polacel is a company of the GEA Group AG. The GEA
Group, headquartered in Bochum, Germany, is a globally suc-
cessful technology group with more than 250 companies in
50 countries.

Evaporation and direct heat exchange cause the temperature to
fall rapidly. Compared to counterflow cooling towers, induced-
draught crossflow cooling towers are much quieter and smaller.
The performance figures are next to perfect.
The effect of crossflow[System‘s functions]
Using the crossflow principle, warm water flowing down
through a cooling unit is cooled by air drawn upwards by a
fan.
The Polacel crossflow cooling tower is quiet and econo mical, and
has a high cooling capacity. The modular system can be easily ad-
justed to suit cooling requirements and the space available. The
cooling towers have optimal performance and run problem-free.
The considerable savings in water usage (95%+), and the excepti-
onally low noise level make the economical crossflow cooling to-
wers the best choice for both man and the environment.
GEA Polacel crossflow cooling towers
[Know how]
Polacel designs, manufactures and maintains cooling towers
for process and climate cooling. Our energy-efficient and en-
vironmentally cooling water generators stand out because of
the complete quality policy we employ.
Cooling Tower type 3 XMS 2.720
Telephone-/Communication center in
the Netherlands
Placing Cooling Tower with crane on steel construction
This temperature is measured by wrapping a glass thermometer
in a cotton cover that has been soaked in water, and placing it in a
stream of air. The water will evaporate and extract heat (sweating
during physical exercise performs the same function and makes a
‘cooling tower’ out of our skin). The wet bulb temperature is there-
fore lower than the ambient temperature.
Cooling towers try to achieve this minimum temperature the most
economic and efficient way possible. The GEA Polacel crossflow
cooling tower range achieves this and successfully balances coo-
ling performance with low power consumption (low cost) and low
noise.
Measuring cooling performance: the wet bulb
[Maximum efficiency]
The wet bulb temperature is in fact the lowest temperature
that can be achieved by air cooling in any given situation.
GEA Polacel assesses the specific requirements together with the
client, and uses this assessment to develop a suitable design. The
expandable modular system is flexible enough to solve all kinds of
capacity demands as ‘standard’. However, for the customer with
special needs, the Polacel engineers will build a tailor-made solution.
Made-to-measure comes as standard
[Modular system]
When choosing a cooling tower, the four most important fac-
tors are: the cooling water temperatures (inlet and outlet),
the wet bulb temperature, the noise emissions, and the water
requirements.

Other prominent distinguishing features of the crossflow
design are:
The design of the fan section and the larger fan ensure
lower energy consumption and result in an important
reduction in noise.
A crossflow cooling tower with a large axial fan uses
around 70% less energy than a counterflow cooling tower
with a centrifugal fan.
Using a geared motor to drive the fan, the cooling
capacity can easily be adjusted as required.
The pressure-less water distribution system is energy-
efficient, and the water pan is easy to clean.
The cooling units are mounted in such a way as to make
cooling per unit possible. The advantages of this
technique are savings of energy, the ability to adjust the
capacity, and the easy access for maintenance. Capacity
can also be adjusted by regulating the water flow. (The
water distribution system and the cooling units can be
adjusted to suit the amount of water used.)
The air inlet louvres create ideal air inflow and minimize
water loss caused by splashing.
The design takes into account the possible need for
variation in capacity, operation during maintenance, and
other features the client may require.
Clients can choose from four standard models in the
crossflow range, each model with different air speeds.
In order to reduce noise levels, GEA Polacel has created a number
of important features. Larger fans (lower speed, less noise, greater
efficiency), pressure-less water distribution, cooling units that run
down into the water tank, and other noise-reducing measures all
combat the various problem areas.
GEA Polacel makes detailed calculations to show exactly what, and
how much, noise the cooling tower will make. GEA Polacel can
also make advance calculations for all the requirements that are
placed on cooling towers by noise regulations and environmental
permits.
Noise and other environmental considerations
[Low Noise]
Cooling towers are usually mounted outdoors, often on a roof
and in the middle of a residential area. That is why any noise
caused by the fan, falling water, the electric motor and the
gearing could pose a potential problem.
Structural qualities
The advanced design engineering has also resulted in
a number of special structural advantages:
Only a minimum number of support points are
necessary as a result of the self-supporting
foundations and the high internal rigidity.
Where possible, the cooling tower is fully portable
and installed ready-to-go.
The GEA Polacel frost-proof polyester water pan
can withstand sub-zero temperatures. Essential
for free-cooling applications.
Due to their low profile, crossflow cooling towers
present fewer aesthetic problems.
The expandable modular system has virtually no
limitations in terms of shape and size.
All structural design principles are analysed and
tested in advance using dynamic calculations and
computer studies.

The GEA Polacel service department specializes in cooling tower
maintenance. Irrespective of make or type, the maintenance spe-
cialists know the ins and outs of the whole technical area, and
are up to date with all the latest developments. GEA Polacel has
over thirty years of experience in cooling tower maintenance. We
work in accordance with the requirements specified by ISO, VCA,
VDMA, CTI and Eurovent. The technicians can carry out the pro-
per maintenance at any location and within practically any time-
frame.
Advice and service[All around support service]
GEA Polacel builds cooling towers that meet exact specifica-
tions. Our sales engineers give advice, analyse your needs, and
personally make sure, up to and including the installation,
that your order is carried out completely according to your
instructions.
This performance is achieved by a careful choice of materials -
stainless steel com bined with glass fibre reinforced polyester and
plastics - the exceptionally sound design and the considerable ex-
perience of our engineers. ‘Cheap and cheerful’ solutions such as
fans with a V-belt drive, or painted panels, are avoided. The result
is a cooling tower that is low maintenance, economi cal and able to
deliver a consistently high quality, problem-free performance.
Durable and reliable[Maximum quality]
GEA Polacel designs and manufactures cooling towers that
have a long life and require a minimum of maintenance.
