Proven Performance & Design FlexibilityThe new PMTQ Cooling Tower offers more capacity and greater systemdesign flexibility than ever before. EVAPCO's research and developmentteam has invested hundreds of hours in laboratory testing to develop thenext generation in Forced Draft Cooling Tower Technology. These effortshave produced a totally new fan section design which is now combinedwith the proven EVAPAK® Fill technology to offer improved performance.

The PMTQ features more plan area options and fan horsepower optionsfor the system design engineer. With more capacity, more plan areaoptions and greater flexibility in motor selection, the design engineer cannow match the performance to the specific application requirements.More equipment choices and more design flexibility mean greater valuefor the End-User.

Patented EVAPAK® FillThe Evapak® film type fill design used in the PMTQ Cooling Tower line isspecially designed to induce highly turbulent mixing of the air and waterfor heat transfer. Special drainage tips allow high water loadings withoutexcessive pressure drop. The fill is constructed of inert polyvinyl chloride,(PVC). It will not rot or decay and is formulated to withstand watertemperatures of 55°C. The fill also has excellent fire resistant qualitiesproviding a flame spread rating of 5 per ASTM-E84-81a. (The flamespread rating scale ranges from 0 for non-combustible to 100 for highlycombustible). Because of the unique way in which the cross-fluted sheetsare welded together, the structural integrity of the fill is greatlyenhanced, making the fill usable as a working platform.

A high temperature fill is available for water temperatures exceeding55°C. Consult your EVAPCO representative for further details.

Energy Efficient for Lowest Operating Cost

Lower Horsepower Options

The new fan drive system of the PMTQ utilizes larger diameter vane-axial fans in a two stage arrangement to providemore efficient air flow and reduced power consumption. When compared to the traditional centrifugal fan cooling towermodels, the vane-axial fan design can offer up to a 50% reduction in energy consumption. And, with the new PMCQmodel selections even more low horsepower options are available to obtain greater energy savings.

Individual Fan Drive SystemCapacity Control Flexibility & Operating Redundancy

The new PMTQ fan drive system provides individualmotor to fan configuration as standard equipment onall models. The dedicated fan to motor arrangementensures less “wear & tear” on the drive system versustandem fan motor drive arrangements resulting in lessmaintenance. The individual motor to fan designoffers greater capacity control flexibility to match thesystem load requirements. In addition, all Evapcotowers are equipped with an internal baffle in thepan bottom vertically up. This unique design allowsthe user to cycle fan motors independently withoutharmful effects of air by-pass inside the unit. Theindividual motor to fan design ensures maximumoperating redundancy in the tower fan system whencritical operation is necessary.

EVAPCOAT Corrosion Protection System

The Z-725 Mill Hot-Dip Galvanized Steel Construction is theheaviest level of galvanizing available for manufacturingevaporative cooling towers and has more zinc protection thancompetitive designs using Z-275 and Z-600 steel.

There are various grades of mill galvanized steel each withdiffering amounts of zinc protection. EVAPCO has been a leaderin the industry in developing heavier galvanizing, and was thefirst to standardize on Z-725 mill hot-dip galvanized steel. Z-725designation means there is a minimum of 725 g/m2 total zincpresent on the steel. During fabrication, all panel edges arecoated with a 95% pure zinc-rich compound for extendedcorrosion resistance.

85% Fewer Fasteners - Lower Installed Cost

The PMTQ features a new field seam design which ensures easierassembly and fewer field seam leaks. The field seam incorporatesnew self-guiding channels to guide the fill section into positionand set in place on the bottom fan section of the tower. Inaddition, the new design eliminates up to 85% of the fastenerstypically used to join the sections in the field significantly reducingthe contractor labor costs for installation.

Unique Seam Design - Eliminate Field Leaks

The new PMTQ features Evapco's unique panel construction designwhich includes a special butyl tape sealer with an integral sealinggasket. Each joint is then backed with a secondary caulkingcompound and encased in a double-brake flange for addedstrength and structural integrity. This unique sealing system hasbeen proven effective in both laboratory tests and years of fieldapplication.

Superior Water Saver Drift Eliminators

The PMTQ incorporate a patented* highly efficient PVC drifteliminator. The eliminator removes entrained water droplets from theair stream to limit the drift rate to less than 0.001% of therecirculating water rate. The efficient of the eliminators is certified byEurovent and tested in accordance with OM-14-2009. Please consultwww.eurovent-certification.com for additional informations.

With a low drift rate, PMTQ towers save valuable water and watertreatment chemicals. The eliminators feature a honeycomb designwhich offers greater structural integrity and are recessed in the top ofthe casing for longer life. They are constructed of inert polyvinylchloride (PVC) which eliminates corrosion in this critical area of thetower. The eliminators are assembled in sections for easy handlingand removal for fill and water distribution system inspection.

Two Speed MotorsTwo speed fan motors can provide an excellent meansof capacity control. In periods of lightened loads orreduced wet bulb temperatures, the fans can operateat low speed, which will provide about 60% of fullspeed capacity, yet consume only about 15% of thepower compared with high speed. In addition to theenergy savings, the sound levels of the units will begreatly reduced at low speed.

Inverter Duty Fan MotorsInverter Duty Fan Motors are available for coolingapplications which utilize variable frequency drivesystems for capacity control. Inverter Duty Fan Motorsoffer totally enclosed premium efficiency constructionwhich is designed for variable frequency driveapplications.Note: Other special motor configurations are availableto meet specific proper requirements. Contact yourlocal EVAPCO sales representative for applicationassistance and motor availability.

Remote Sump ConfigurationFor units operating in areas where temperatures maybe very low, or where low temperatures may occurduring periods when the unit is not operating, a sumplocated inside the building is the preferred means ofensuring that the basin water will not freeze. For theseapplications, the cooling tower will be suppliedwithout the spray pump, suction strainers but with anoversize bottom outlet.

Electric Water Level ControlCooling towers may be ordered with an electric waterlevel control in lieu of the standard mechanical floatand make-up assembly. This package provides accuratecontrol of water levels and does not require fieldadjustment.

Basin Heater PackageElectric immersion heaters are available factoryinstalled in the basin. They are sized to maintain a+5°C pan water temperature with the fans off and anambient air temperature of -18°C.They are furnished with a combination thermostat/lowwater protection device to cycle the heater on whenrequired and to prevent the heater elements fromenergizing unless they are completely submerged.All components are in weather proof enclosures foroutdoor use. The heater power contactors and electricwiring are not included as standard.

I B C C E R T I F I C AT I O N

What is IBC?

International Building Code

The International Building Code (IBC) is a comprehensive set ofregulations addressing both the structural design and theinstallation requirements for building systems – including HVACand industrial refrigeration equipment. Compared to previous building codes that considered only thebuilding structure and component anchorage, the requirementscontained within the IBC address anchorage, structural integrity,and the operational capability of a component following eithera seismic or wind load event. Simply stated, the IBC codeprovisions require that evaporative cooling equipment, and allother components permanently installed on a structure, mustbe designed to meet the same seismic or wind load forces asthe building to which they are attached.

How Does IBC 2009 Apply to Cooling Tower?Based on site design factors, calculations are made to determinethe equivalent seismic “g force” and wind load (kilo-Newton persquare meter, kN/m2) on the unit. The cooling tower must bedesigned to withstand the greater of either the seismic or windload.All locations with design criteria resulting in a seismic designforce of up to 1.0g or a wind load of 2,87 kN/m2 or below willbe provided with the standard PMTQ structural design. Anupgraded structural design is available for installations withdesign criteria resulting in “g forces” greater than 1.0g. Thehighest “g force” location in North America is 5.12g. Thehighest wind load shown on the maps is 273 km/h, which isapproximately equal to 6,94 kN/m2 velocity pressure.Therefore, the upgraded structural design package option forthe New PMTQ is designed for 5.12 g and 6,94 kN/m2 making itapplicable to most building locations all over the World.

Design ImplementationEVAPCO applies the seismic design and wind load informationprovided for the project to determine the equipment designnecessary to meet IBC requirements. This process ensures thatthe mechanical equipment and its components are compliantper the provisions of the IBC as given in the plans andspecifications for the project.

Independent Certification

Although the IBC references and is based on the structuralbuilding code ASCE 7, many chapters and paragraphs of ASCE 7are superceded by the IBC, independent certification andmethods of analysis are such paragraphs. Per the most recentedition of the code, the EVAPCO compliance process included an

exhaustive analysis by an independent approval agency. Asrequired by the International Building Code, EVAPCO supplies acertificate of compliance as part of its submittal documents. Thecertificate of compliance demonstrates that the equipment hasbeen independently tested and analyzed in accordance with theIBC seismic and wind load requirements. Evapco has workedclosely with the independent approval agency, The VMC Group,to complete the independent equipment testing and analysis.

For further questions regarding IBC compliance, please contactyour local EVAPCO Representative.

In its continuing commitment to be the leaders in evaporative cooling equipmentdesign and services, EVAPCO PMTQ Cooling Towers are now Independently Certified

to withstand Seismic and Wind Loads in accordance with IBC 2009.

C EUROVENT – CTI cooperation

EUROVENT AssociationInitially founded in 1958EUROVENT Associationrepresents the Europeanrefrigeration, air conditioning,air handling, heating and ventilation industry and tradeassociations from European and non-European countries.Over 1000 companies in 13 European countries,employing 150000 employees who jointly generate morethan € 25 to 30 billion of annual output are member ofthis organization.

EUROVENT missionEUROVENT represents, promotes and defends the industryto relevant national and international bodies andcooperates with other European umbrella associations.Over the years EUROVENT has become a well-known andrespected stakeholder in all industry related matters and, inparticular, in climate change and energy efficiency. EUROVENT develops product certification programs for theentire industry through the EUROVENT CertificationCompany.

EUROVENT CertificationThe main objective of theEUROVENT CertificationCompany (ECC) is tocertify cooling equipment(and/or components)

independently from EUROVENT Association. With acommon set of well-defined procedures and criteria forthe rating of products, comparison of productperformance ensures a healthy and solid competitionon a market open to all manufacturers. When amanufacturer participates in a certification program, hehas to present its list of models or model rangestogether with their performance data. The files areevaluated by the ECC Certification and a predefinednumber of units are selected for testing by independentlaboratories. If the results comply with the relevantstandards, the submitted models or ranges will be listedin the EUROVENT Certification Online Directory. Modelsare subject to regular random testing to verifycompliance with catalogue data.

BenefitsThe Certification Mark guarantees specifying engineers,installers and end users that the products marketed by aparticipant have been submitted to independent testingand that they have been accurately rated. Through specification of certified products, theengineer's tasks become easier, since there is no need tocarry out detailed comparison and performance testing.

In 2007 Evapco launched the initiative to create the “European Chapter” of CTI.At the start of this initiative, Eurovent and CTI established a “Memorandum of Understanding”.Since then the “Operational Manual for Certification of Cooling Towers” and the “EuroventRating Standard for Cooling Towers” were written. Both documents are strongly tied to theCTI documents STD 201 and ATC 105. A common “CTI-EUROVENT” Certification program hasbecome the European Standard for independent thermal performance rating of cooling towers.

All Evapco CTI Certified cooling towers will be CTI-ECC certified as from February 2012.

Principle of Operation

Warm water from the heat source is pumped to the waterdistribution system at the top of the tower. The water isdistributed over the wet deck fill by means of EvapJet™nozzles. Simultaneously, air is blown into the basinsection of the tower and travels upward through the wetdeck fill opposite the water flow. A small portion of thewater is evaporated which removes the heat from theremaining water. The warm moist air leaves the top ofthe cooling tower to the atmosphere. The cooled waterdrains to the basin of the tower and is returned to theheat source.

Steel Support

The recommended support for EVAPCO cooling towers isstructural “I” beams located under the outer flanges andrunning the entire length of the unit. Mounting holes,19 mm in diameter are located in the bottom channels ofthe pan section to provide for bolting to the structuralsteel. (Refer to certified drawings from the factory forbolt hole locations.)

Beams should be level to within 3 mm in 1,8 m beforesetting the unit in place. Do not level the unit byshimming between it and the “I” beams as this will notprovide proper longitudinal support.

ENGINEER ING DATA & DIMENS IONS

PipingCooling tower piping should be designed and installed inaccordance with generally accepted engineering practices.All piping should be anchored by properly designedhangars and supports with allowance made for possibleexpansion and contraction. No external loads should beplaced upon cooling tower connections, nor should any ofthe piping supports be anchored to the unit framework.

Capacity ControlThe design wetbulb for which the tower is sized occursonly a small percentage of the time. Unless colder watertemperatures are beneficial to the process being cooled,some form of capacity control will be needed. A commoncontrol practice is to cycle the fans off when leavingwater is below the minimum allowable temperature.However, this does not provide close control of theleaving water temperature and may cycle the motor onand off more than the recommended limit of six (6) startsper hour. Another method is to use a Variable FrequencyDrive (VFD) to control the fan speed. When a VFD isutilized, EVAPCO recommends the use of inverter dutymotors, which are available as standard.Another variable speed option is the use of a 2-speed fanmotor. This arrangement gives three (3) stages of capacitycontrol – 10% with the fans off, 60% (fans at 1/2 speed)and 100% (fans at full speed).Variable speed motors also save operating costs. At half-speed, the motor draws approximately 15% of full loadpower. Since maximum wet bulb and maximum loadseldomly coincide on air conditioning systems, the coolingtower will actually operate at a reduced speed most ofthe time. Contact the factory for a more detailed analysis.Caution: The water circulation pump must be interlockedwith the fan motor starter(s) to ensure water flow overthe tower fill during fan operation.

Maintaining the Recirculated Water SystemThe cooling in a tower is accomplished by the evaporationof a portion of the recirculated spray water. As this waterevaporates, it leaves behind its mineral content andimpurities. Therefore, it is important to bleed-off anamount of water equal to that which is evaporated toprevent the build up of impurities. If this is not done, themineral content and/or the corrosive nature of the waterwill continue to increase. This will ultimately result inheavy scaling or a corrosive condition.

Bleed-offA bleed line should be installed in the piping, external tothe unit. The bleed line must be properly sized for theapplication, and provided with a metering connection andglobe valve. The recommended bleed off for a coolingtower is equivalent to the evaporation ratio of 1,58 l/hper kW of cooling. If the make-up water supplying theunit is relatively free of impurities, it may be possible toreduce the amount of bleed, but the unit must beinspected frequently to make sure scale is not forming.Make-up water pressure must be maintained between 140and 340 kPa for proper operation of the standard floatvalve.

Water TreatmentIn some cases the make-up water will be so high inmineral content that a normal bleed-off will not preventscaling. In this case, water treatment will be required anda reputable water treatment company familiar with thelocal water conditions should be consulted. Any chemicalwater treatment used must be compatible with thematerials of construction of the unit. The pH of the watershould be maintained between 6.5 and 8.3. In order toprevent “white rust”, the galvanized steel in the unit mayrequire routine passivation of the steel when operating inhigher pH levels. Batch chemical feeding is notrecommended because it does not afford the properdegree of control. If acid cleaning is required extremecaution must be exercised and only inhibited acidscompatible with galvanized steel construction should beused.

Control of Biological ContaminationWater quality should be checked regularly for biologicalcontamination. If biological contamination is detected, amore aggressive water treatment and mechanical cleaningprogram should be undertaken. The water treatmentprogram should be performed by a qualified watertreatment company. It is important that all internalsurfaces be kept clean of accumulated dirt and sludge. Inaddition, the drift eliminators should be maintained ingood operating condition.

NOTE: The location of the cooling tower must beconsidered during the equipment layout stages of aproject. It is important to prevent the discharge of air(potential of biological contamination) from beingintroduced into the fresh air intakes of the building
