)Improvementl
Talking to sales engineers
Polacel is a manufacturer of cooling towers. A coo
ling tower is a technical product that has to meet
precise specifications.
This is why our sales organization relies on our sales
engineers, who are qualified professionals with specific
know-how. They give advice, analyze your wishes and
take personal responsibility for delivery so that your
order is completely in line with your instructions.
)Modular system)
Manufacturing andinstallation
Polacel manufactures modules to size on the basis
of the data we have compiled. We produce smaller
units that are delivered ready to install as well as
large cooling towers, which we assemble on site.
Customer-specific requirements can easily be accommo
dated thanks to the modular system. Client wishes
also form the basis of the installation phase. We can
supply the installation ready to operate within a short
delivery period.
[Servicel
Polacel's service organization
Polacel's own service organization specializes in the
maintenance of all cooling towers and it knows all
the ins and outs of the whole technical area.

ISyltt'm's functions]
The effect of counterflow
CMC cooling towe.. work on the principle of counterflow.
This means lhat lhe waler flows down while lhe air is pulled
upwards by a fan.
As the water nows further through the system, the air it enconn
leTS is fresher, in other wonls cooler and less saturated with moi
sture. Counternow cooling towers can approach the wet hulb tem
perature better compared to cro5sflow cooling towers.
{Knowhow]

Cooling performance measured:the wet bulb
The wet bulb temperature is in fact the lowest temperature
that can be achieved by air cooling in any particular set of
circumstances.
This temperature can be measured by wrapping a glass therm(r
mcter in a piece of cotton that has been drenched in water and
placing it In a streanl of air. The w~ter will evaporate ~nd lose
heat (swealiug while takiug exercise has the same funcHon and
makes a 'cooling tower' out of our skin). The wet bulb temperature
is therefore lower than the ambient temperature.
Cooling towcrs try to approach this achievable minimum tern·
perature usillg as little ellcrgy and as efficieutly as possible. Thc
GEA rolacel CMC range succeeds ill doing this alld combines
maximum efficiency with low power consumption, anu therefore
minimal costs.
IModular systeml
Modules to size
The cooling water temperatures (inlet and outlet), the wet
bulb temperature, noise and the water load are the four most
important factors in the selection of a cooling tower.
GEA Palacel makes an inventory of the requirements together
with thr. client and IISCS this inventory as the basis of the design
for a suitable solution. The modlll~r CMC system can be extended.
and there .Ire standard solutions available for different capacity
needs. GEA Palacel engineers make customized changes to meet
special requirements.
ISllentnessl
Noise reduction
As a rule cooling towers are outdoors, and usually on a roof
or at the edge of the site, The noise produced by the cooling
tower caused by, among other things, the fan, falling water,
the electrical motor or geared motor. can therefore present a
problem.
GEA Polacel has put a number of development~into practice that
rr.duce the noise nuisance. larger fans (lower speed. less noise
and higher efficiency). floating silcncers to reduce the noise of
splashing and other noise reducing measures combolt the different
sources of noise.
GEA Palacel provides a detailed picture of the nature and level of
the noise produced by means of detailed calculations. GEA Polacel
can also make calculations for all cooling towers beforehand in
relation to the requirements laid down ill euvirollmental permits.

2H Structured Media PP vs. PVC
At present about 25% of 2H structured media is made from polyvinyl chloride (PVC)and 75% from polyp.ropylene (PP). We claim to have gained considerable experienceof both products over the past 15 years.
2H :find PP media has the following advantages:
~ It is more consistent in properties than PVC• Stronger than PVC• Has better operational properties such as wetting• Is less expensive to produce and sell• lIealthier for the work force• Has a lower cost of ultimate disposal
Some of these findings are apparently contrary to published polymer property dataand so require clarification and expansion. As is often the case, it is "not what you dobut how you do it" which provides the explanation.
Consistent properties
All PVC media is made from reground scrap. It is calendared to a flat sheet, usuallyby a specialist manufacturer. Then the media producer theono or vacuum forms thesheet to a corrugated or profiled surface which is then trimmed to size. The sheets arecoated with- solvent based -adhesives, stacked into a jig and left to dry. Sometimes,aqueous based adhesives are used but these produce weaker bonds and they alsocontain some solvent.
PP media is made from virgin polymer compounded with inert additives and passedthrough a standard plastic sheet extruder. The molten extruded sheet is fed directlyinto a revolving forming tool, cut to length and welded into blocks in one continuousprocess. The automatic welding device controls temperature, pressure, time andcooling cycle to close tolerances.
pp blocks produced by this method have fewer steps in their production and,importantly, the polymer is subjected to leastlwo less melting cycles than glued PVC.Every time a polymer undergoes amelting cycle, some degradation occurs.
With PP the handwork element of gluing is removed. Overall, the human factor ismuch reduced.

PP is stronger than PVC
To welding plant
Not according to published data: this indicates that the ultimate tensile strength oftypical PVC is about 160% that of typical PP. Yet 2H PP blocks can be producedwhkh sustain the weight offully loaded articulated trucks. Similarly, it is possible tobuild heavily loaded high rate tilters t.o 8m depth or more from PP media.
Following extensive independent evaluations by the TUV in Germany, 2H are able towan"antee their PP dynamic loading solutions for 30year+ lifetimes. So far this hasnot been done for glued PVc.
2H PP media achieve their exceptional mechanical performance for the foUowingreasons:
• The density difference between PVC and Polypropylene polymers is about40%. This allows thicker foils to be made from PP fOJ" equivalent weight toPVC offsetting the strength difference.
• The 21-1 process allows strengthening of the media block where the loads areheaviest
• The compounded fillers significantly improve the long-term strengthproperties of the PP block

PP and some PVC media contain UV additives to improve weatherability. Ev.aluationis ongoing. S:o far, long terJn tests (10 year~) indicate similar results for PVC and PPmedia i.e. good resistance. It is predicted, however, thaUhe greater [oil thickness ofPP media could give it the edge over tlie long teon. In Western Europe projected lifefor both PVC and PP media is in exces~ of 30 years.
PP media bas better operational p"operfies such as wetting
Studies by CAMRE at Potion Down, originally into the growth of LegionelJa inpipework, show that the growth ofbiomass on PP is more rapid than on PVC. ThisI.eads to faster filter start-ups from PP. Meeting outlet consents withjn two weeks isnot ullusual.
The compounding of PP with fillers has the effect of roughening the surface andreducing the surface energy ofPP media. In practice, this allows enhanced wettingand biomass retention. Independent studies show the perfOlmance of cooling towerfill fi'om 2H media is virtually identical to PVC. Thi.s would not be the case forunmodified PP.
PP has generally better chemical resistance than PVC and its contit1U"ous operatingtemperature is at least 8ddegC compared to PVC's 55degC. This is of considerableimportance for cooling tower operation.
In the field, 2H PP media ios significantly more robust than PVC. This allows fasterinitial installation, safer-walk~on conditions and easy removability of blocks forroutine biomass inspections.
pp media is less expensive than PVC to produce-and to seU
Generally speaking PVC polytner is less expensive tha.!'l PP polymer but PP med.ia isoften less expensive than PVC media becaus~:
• The weight per specific volume of PP is less than PVC (0.91: J.42) - Thls isonly p&rtly negated by the greatel' thickness of2HPP media foils
• Precise control of sheet thickness by the 2H manufacturing process• Fewer manufacturing steps• Automated process (lower labour costs)
• No glue• No solvent recovery plant -investment and operation costs

PP is healthier for the workforce than PVC
Matters of health are always contentious as most materials can be hazardous ifmishandled. 2H strongly recommend that all users of plasti~s materials strictly followmanufacturer's safety requirements.
PVC is halogenated and is built into blocks by using solvent based adhesives. Suchproducts call- be toxic even in small amounts and especially, when ingested or inhaledover prolonged periods.
Balogem and solvents are absent from PP media and from its construction processes.So Tisks associated with them are also absent. ft is also worth noting that, in theinstance of those hazards mentioned luwe, when PP media is used, the possibility of anafflicted person bringing legal action against a user who persists in purchasing PVCmedia when a safer alternative is available is also eliminated.
PP has a lower cost of ultimate disposal than PVC
PVC is a halogenated product. Already in certain parts of Europe disposal by landfillexcept under very special circumstances and at great cost is proillbited for this class ofchemical. Similarly, incineration is very expensive.
It can be expected that the trend towards greater harmonisation of regulationsthroughout Europe will create a situation where the inevitable disposal of PVC mediamay prove more expensive than the initial installation.
At present P-P can be disposed by landfill without additional cost penalties. Beingnon-halogenated it can also be incinerated at less cost than PVC.

Thermal Engineering
The maximum evaporation, which determines the design for the make up and drain, can be 25% higher.
Drain loss : Depends on the water quality
Sound power cooling tower
The total sound power (PWL) of the cooling tower is determined by the logarithmic summation of the partial sources: fan outlet and air inlet. The noise at the air inlet is caused by the falling of the water in the water pan. This noise can be attenuated using floating noise attenuators, a special Polacel development. The values are calculated according to DIN 45635 Sub 46, class 3. The sound pressure at a certain distance can be calculated using the table “conversion from sound power to sound pressure for counter flow cooling towers”. PWL – fan outlet : 105.0 dB(A)
PWL – air inlet without attenuators : 107.5 dB(A)
PWL – cooling tower total (excl. att) : 108.3 dB(A)
