ILongevityl

Cooling towers save

Cooling towers for process and climate cooling are energy­

efficient and environmentally-friendly generators of cooling

water.

Polacel cooling towers achieve a up to 95% and above saving in

water, a thermal load on surface waters that stays well within

the legal limits and substantially lower climate cooling costs.

Our cooling towers have a particularly long lifetime and are

very low-maintenance. Polacel is the best choice for man and his

environment.

The complete pathway

Polacel is involved in the cooling towers we supply from the

first introductory discussion, through the manufacturing stage

to maintenance and service after installation.

We know and understand the complete pathway, we have all the

data and specifications and we can accommodate all wishes and

requirements in our own field. This makes Polacel a permanent

source of support and partner for our customers throughout all the

years that our cooling towers are in service.

)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.

The scopeofthe services includes scheduled maintenance,

capacity measurement, overhauls and the upgrading of

cooling towers. The Polacel service organization takes

care of clients' cooling tower installations in order

to make the operation problem-free and perform

superbly.

[Communicationl

The Polacel approach

Polacel believes in direct contacts and short lines

of communication. The organization is transparent

and our customers always have a permanent focal

point.

Up to and including completion this is the sales

engineer, a specialist who also remains involved in the

cooling tower afterwards. Once your cooling tower is in

operation, there is a permanent internal contact person

for all practical matters, such as maintenance.

[Conditionsl

Purchase, hire, hire purchaseand lease

Customization is also our standard approach to sales

policy. Clients are free to choose the form of purchase,

hire or lease that suits them best.

[Optionsl

New, used, trade in andbuy-back

Polacel makes durable, quality cooling towers. When

growth makes the capacity of a cooling tower too small,

for example, you can trade it in. The used tower is then

sold, after a thorough overhaul (as good as new, but at

a second-hand price).

GEA Polacel

GEA Polacel is a company of the GEA Group AG. The GEA

Group. headquartered ill Bochum. Germany. is a globally suc­

cessful technology group with more than 250 companies in

50 countries.

The company now focuses on specialty mechanical engineering

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]

Polacel CMC cooling towers

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)
