MH Fluid Cooler — Engineering Data: Freeze PreventionFLUID COOLER COILFLUID COOLING RECIRCULATING WATERWhen the ambient temperature falls below 32 F, heatloss from the coil be substantial even without recirculatingwater flowing over the coil. The process fluid, without anapplied heat load, may be prone to freezing. There are variousmethods to protect against coil freezing.When the ambient air temperature falls below 32 F, therecirculating water within the fluid cooler can freeze. MarleyTechnical Report #H-003 “Cooling Towers and FreezingWeather” describes how to prevent freezing during operation.Ask your Marley sales representative for a copy or downloada copy at spxcooling.com.Ethylene and propylene glycol solutions are the bestmeans to protect against coil freezing and are recommendedfor most installations. The appropriate concentration ofethylene or propylene glycol should be determined based onthe required protection from low ambient temperatures.If the use of an industrial antifreeze solution is notcompatible with the system, another accepted method ofpreventing coil freezing is to maintain a sufficient flow rateand heat load on the process fluid. The fluid exiting the coilmust be maintained at or above 45 F at the full process flowrate. If the process load does not yield such a heat load, itmay be necessary to apply a supplementary heat load to theprocess fluid.Draining galvanized steel coils is not considered to be anacceptable means of protection against freezing. Introducingair to the inside of the heat exchanger coil will promotecorrosion. In an emergency, this alternative can be usedin the event that the process fluid drops below 45 F, theambient temperature is below freezing and the coils are notprotected with industrial antifreeze. Copper coils and series300 stainless steel coils may be drained as necessary withoutsignificantly increasing corrosion risk.Cycling of the recirculating water pumps to controlprocess flow temperatures must be approached with caution.Frequent cycling of the recirculating water pump may leadto an excessive scale buildup resulting in a decrease inefficiency.During shutdown, water collects in the basin and mayfreeze solid. You can prevent freezing by adding heat to thewater left in the basin—or, you can drain the tower and allexposed pipework at shutdown.ELECTRIC BASIN HEATERSAn automatic basin water heater system, consisting of thefollowing components: Stainless steel electric immersion heater(s).Threaded couplings are provided in the side ofthe collection basin. NEMA 4 enclosure containing:Magnetic contactor to energize heater.Transformer to convert power supply to 24 voltsfor control circuit.Solid state circuit board for temperature andlow-water cutoff.The enclosure may be mounted on the side of thefluid cooler. Control probe in the collection basin to monitorwater temperature and level.The basin heater option is only for freeze protection of therecirculation water in collection basin. The basin heater optiondoes not protect the coil during freezing weather.Heater components are normally shipped separately forinstallation by others.INDOOR STORAGE TANKCAUTIONFreezing ambient conditions could cause significantdamage to the heat exchanger coil of the MH FluidCooler. To avoid possible damage, it is imperative toprovide for adequate freeze protection.With this type of system, water flows from an indoor tankand back to the tower where it is cooled and recirculated. Thewater flows by gravity from the fluid cooler to the tank locatedin a heated space. At shutdown, all exposed water drains intothe tank where it is safe from freezing.The amount of water needed to successfully operate thesystem depends on the fluid cooler size on volume of watercontained in the piping system to and from the tower. Youmust select a tank large enough to contain those combinedvolumes—plus a level sufficient to maintain a flooded suctionon your pump. Control makeup water according to the levelwhere the tank stabilizes during operation.7
MH Fluid Cooler — Engineering Data: Water QualitySYSTEM CLEANLINESSWATER TREATMENTThe MH Fluid Cooler can be a very effective air washer.Atmospheric dust able to pass through the relatively smalllouver openings will enter the recirculating water system.Increased concentrations can intensify systems maintenanceby clogging screens and strainers—and smaller particulatescan coat system heat transfer surfaces. In areas of low flowvelocity—such as the collection basin—sedimentary depositscan provide a breeding ground for bacteria.To control the buildup of dissolved solids resulting fromwater evaporation, as well as airborne impurities and biologicalcontaminants including Legionella, an effective consistentwater treatment program is required. Simple blowdown maybe adequate to control corrosion and scale, but biologicalcontamination can only be controlled with biocides.In areas prone to dust and sedimentation, you shouldconsider installing some means for keeping the collectionbasin clean. Typical devices include side stream filters and avariety of filtration media.BLOWDOWNBlowdown or Bleedoff is the continuous removal of asmall portion of the water from the open recirculating system.Blowdown is used to prevent the dissolved solids fromconcentrating to the point where they will form scale. Theamount of blowdown required depends on the cooling range—the difference between the hot and cold water temperaturesof the closed circuit— and the composition of the makeupwater. The MH Fluid Cooler is equipped with a blowdownline with metering valve connected directly to the overflow.Specific blowdown adjustment instructions and additionalblowdown information can be found in the MH Fluid CoolerUser Manual.CAUTIONThe fluid cooler must be located at suchdistance and direction to avoid the possibilityof contaminated discharge air being drawninto building fresh air intake ducts. Thepurchaser should obtain the services of aLicensed Professional Engineer or RegisteredArchitect to certify that the location of the fluidcooler is in compliance with applicable airpollution, fire and clean air codes.An acceptable water treatment program must becompatible with the variety of materials incorporated in a fluidcooler—ideally the pH of the recirculating water should fallbetween 6.5 and 9.0. Batch feeding of the chemicals directlyinto the fluid cooler is not a good practice since localizeddamage to the fluid cooler is possible. Specific startupinstructions and additional water quality recommendationscan be found in the MH Fluid Cooler User Manual whichaccompanies the fluid cooler and also is available from yourlocal Marley sales representative.8

During the planning and layout stages of your project, you will have focused your attention on a fluid coolerselection that fits your space allotment, and whose power usage is acceptable.Limitations on physical size and total operating horsepower avoid the introduction of unforeseen operational and site-related influences. Specifying the number of cells, and the maximum fan hp/cell will work to your advantage.The benefit of crossflow fluid coolers is that they are inherently easy to operate,access, and maintain. Unlike counterflow fluid coolers, crossflow fluid coolers have a spacious plenum between banks of fill for easy access to all of thetower’s internal components, and the water distribution system is adjacent tothe fan deck. C ertification means that the fluid cooler has been tested under operating conditions and found to perform as rated by the manufacturer under those circumstances. It assures the buyer that the tower is not intentionally or inadvertentlyundersized by the manufacturer. The MH Fluid Cooler has been tested and performance certified with water, ethylene glycol solutions up to 50% concentrationand propylene glycol solutions up to 50% concentration.The minimum efficiency per ASHRAE Standard 90.1-2010 for axial-fan closedcircuit cooling towers applied to comfort cooling is 14.0 gpm/hp at 102 F /90 F / 75 F, where hp is the sum of the fan motor nameplate power and theintegral spray pump motor nameplate power. If a greater efficiency is desired, ahigher ASHRAE Standard 90.1 gpm/hp can be specified. Each model’s ratingat ASHRAE Standard 90.1 conditions can be viewed in our online selectionsoftware at spxcooling.com/update.
MH Fluid Cooler — Specifications: BaseSpecifications3.0Performance Warranty:3.1CTI and Eurovent Certification notwithstanding, the fluid cooler manufacturershall guarantee that the fluid coolersupplied will meet the specified performance conditions when the fluid cooleris installed according to plans. If, becauseof a suspected thermal performance deficiency, the owner chooses to conduct anon-site thermal performance test underthe supervision of a qualified, disinterested third party in accordance with CTI,Eurovent or ASME standards during thefirst year of operation; and if the fluidcooler fails to perform within the limits oftest tolerance; then the fluid cooler manufacturer will pay for the cost of the testand will make such corrections as areappropriate and agreeable to the ownerto compensate for the performance deficiency.4.0Coil:4.1Coil(s) shall consist of fully welded boxheaders with serpentine tube circuits andshall be hot-dip galvanized after fabrication. The coil(s) shall be designed for freedrainages of fluid at shutdown. Minimumdesign operating pressure shall be 150psi. Coil(s) shall be warranted against anyfailure caused by defects in materials andworkmanship for a period of eighteen(18) months from the date of shipment.5.0Design Loading:5.1The structure and anchorage shall bedesigned to withstand a wind loadof 50 psf while operating, based onInternational Building Code ASCE7-10,as well as a .3g seismic load. The fluidcooler shall be designed to withstandshipping and hoisting loads of 2g horizontal or 3g vertical. The fan deck and hotwater basin covers on doubleflow modelsshall be designed for 50 psf live load ora 200 lb concentrated load. Guardrails,where specified, shall be capable of withstanding a 200 lb concentrated live loadin any direction, and shall be designed inaccordance with OSHA guidelines.10Specification Value However, certification alone is not sufficient to assure you that the fluid coolerwill perform satisfactorily in your situation. Certification is established under relatively controlled conditions, and fluid coolers seldom operate under such idealcircumstances. They are affected by nearby structures, machinery, enclosures,effluent from other sources, etc. Responsible and knowledgeable bidders willtake such site-specific effects into consideration in selecting the fluid cooler—but the specifier must insist by the written specification that the designer/manufacturer guarantee this “real world” performance. Any reluctance on the part ofthe bidder should cause you some concern. T he MH Fluid Cooler coil is suitable for cooling water, oils, andother fluids compatible with carbonsteel in a closed, pressurized system. Eachcoil is constructed of all-prime surface, continuous steel tubing, formed into a serpentine shape andwelded into an assembly. The complete assembly is thenhot-dip galvanized after fabrication. Tubes are sloped to provide free drainagewhen vented. The indicated design values are the minimum allowables under accepteddesign standards. They give you assurance that the fluid cooler can be shipped,handled, hoisted—and ultimately operated in a normal fluid cooler environment.Most MH Fluid Cooler models will withstand significantly higher wind and seismic loads. If your geographic location dictates higher wind load or seismic loadvalues, please make the appropriate changes, after discussion with your Marleysales representative.
MH Fluid Cooler — Specifications: BaseSpecifications11Specification Value6.0Construction:6.1Except where otherwise specified, allcomponents of the fluid cooler shall befabricated of heavy-gauge steel, protected against corrosion by G-235 galvanizing. After passivation of the galvanizedsteel (8 weeks at pH 7-8, and calciumhardness and alkalinity at 100-300 ppmeach), the fluid cooler shall be capable ofwithstanding water having a pH of 6.5 to9.0; a chloride content up to 500 ppm asNaCl (300 ppm as Cl-); a sulfate content(as SO4) up to 250 ppm; a calcium content (as CaCO3) up to 500 ppm; silica(as SiO2) up to 150 ppm. The circulatingwater shall contain no oil, grease, fattyacids, or organic solvents. In the history of fluid coolers, no other coating for carbon steel has exhibitedthe success and longevity of galvanization in exposure to the normal fluid coolerwater quality defined at left. No paints or electrostatically-applied coatings, however exotic they may be, can approach galvanization's history of success.If extended longevity of the fluid cooler is required—or unusually harsh operatingconditions are expected—consider specifying stainless steel as either the baseconstruction material, or the material utilized for specific components of yourchoice. See Stainless Steel Options on page 14.6.2The specifications, as written, are intendedto indicate those materials that will becapable of withstanding the above waterquality in continuing service, as well as theloads described in paragraph 6.1. They areto be regarded as minimum requirements.Where component materials unique toindividual fluid cooler designs are notspecified, the manufacturers shall takethe above water quality and load carryingcapabilities into account in the selection oftheir materials of manufacture.7.0Mechanical Equipment:7.1MHF7101, MHF7103, MHF7105,MHF7107 and MHF7109 - Fan(s) shallbe driven through a one-piece multigroove, solid back V-type belt.
