For decades, SPX Cooling Technologies has beena leading producer of counterflow cooling towersfor large industrial installations. The Marley MDtakes advantage of this experience by bringing itdown to size.The Marley MD is a factory assembled tower,which makes it a definite go-to solution for lightindustry and HVAC applications.Marley QualityOn A Whole New ScaleWe’re well known for our outstanding crossflowsystems. So why select a counterflow tower?Because the Marley MD tower providescomparable capacity with a smaller footprint,expanding the landscape of possible uses.

Marley MD Cooling Tower:The Right Answer in So Many WaysUnmatched reliabilityLow energy consumptionHeavy-duty construction,high-performance design and ourfive-year mechanical warranty ensuresconsistent, CTI-certified fully ratedcooling over a wide range of flow andtemperature requirements.Induced draft counterflow equipmentminimizes the energy consumptionby providing lower fan energy thancentrifugal fan counterflow units.Smaller footprintInduced draft counterflow designrequires less plan area thancrossflow towers. And becausethe tower’s size results in less steelused, its reduced weight requiresless support structure.Ease of maintenanceSPX has worked hard to addressthe maintenance difficulties longassociated with counterflow towers.Our MD tower provides larger accessdoors, easily removable block filland other features that simplifymaintenance. For European towers,an optional fill removal access door isnow available that complies with HSEACoP L8 requirements.Low-noiseThe Marley MD comes standardwith our CTI-certified low-noise fan,suitable for most noise-sensitivesituations.Superior WaterManagementTo address the “splash-out”problem typically found incompetitive counterflowdesigns, SPX introduces anindustry first: a triple-passinlet louver and drift eliminatorthat conserves water andimproves winter operation.

Why CounterflowMay Be Your Best ChoiceRestricted site conditionsAll This.and Green, TooDesigned to beenvironmentallyresponsible, the MDconserves water bykeeping splash-out toa minimum. And beingremarkably energyefficient, it doesn’twaste asingle kilowatt.Counterflow towers have different footprints from crossflow towers andoffer layout alternatives. Where space is limited or otherwise restricted,the counterflow’s smaller footprint can be a perfect fit. In addition to takingup less site space, counterflow towers may have a lower installed weight.Plus, piping costs can be reduced since a single inlet is usually standard.Operation and maintenance considerationsCounterflows’ tight louvers prevent sunlight from hitting the collection basinand therefore reduce algae growth. Counterflow towers offer easy accessfrom all tower sides. The wet surface is totally enclosed for winter operationand protection from environmental elements, and the towers provide acorrosion-resistant spray system.Value-Added OptionsWelded stainless steelcollection basinSolid-state water levelcontrol packageFor extra protection, allcollection basin parts exposedto circulating water (includingstructural members thatproject into the basin) andall attaching hardware andbasin options are heavy-gaugeseries 300 stainless steel.This package monitorsbasin water levels withsolenoid-valve water makeup.Configurations include makeupalong with high- and low-waterlevel alarm and cutoff, andelectric basin heater cutoff.Electric basin heaterThis electric immersion heateris used to help prevent freezingduring cold weather.Vibration switchThis option protects againstmechanical failure should thetower experience high vibrationlevels by automatically shuttingdown the motor. Manual resetensures inspection to correctinitial vibration cause.Variable speed driveOur variable speed driveprovides the ultimate intemperature and soundcontrol, energy managementand mechanical equipmentlongevity.Control systemsThese range in sophisticationfrom standard fan startersto Programmable LogicControllers that workin conjunction with yourbuilding or process system.Sound attenuationBaffles can be installedacross the length of the airoutlet opening. All bafflesare contained within aself-supporting steel box.Splash attenuation isalso available.
