Daikin Magnitude chillers,peak efficiency year after yearTo instill productivity and promote efficiency, commercialbuildings today must feel as comfortable as they look. That’swhere Magnitude counts most. Magnitude magnetic bearingwater cooled chillers are designed to create the ultimate inclimate-controlled environments for offices, K-12 schools,colleges, hospitals and healthcare facilities for the people whowork, study, teach, heal and recover within their walls. Buildingowners and property managers realize the benefits, too, interms of reliability and performance. And when it comes tosaving energy, Magnitude is up to 40% more efficient thanstandard centrifugal chillers and offers substantially improvedsavings over the life of the unit.Quiet operationThe Magnitude chiller is quiet with sound pressure ratings as low as 76 dBA,tested according to AHRI Standard 575. Sound levels will be even lower atreduced loads and non-standard design conditions.This quiet operation makes Magnitude ideal for sound sensitive environmentssuch as schools, performance halls, museums, and condominiums.

Magnetic bearing compressorsAs reliable as they are efficient Magnetic bearings eliminate mechanical sealsand wear surfaces for longer machine life. The simplicity of a direct-drive motor and shafteliminates gears, slide valves and extra parts toincrease reliability. VFD designed as an integrated component withthe compressor and optimized by digital controlsto reduce power consumption while maximizingchiller performance. Reduced in-rush current by utilizing a VFD; a gradualsoft start that lessens mechanical and thermal stressesleading to increased motor life. Onboard digital controls to continuously monitoroperating status and provide fault protections. Oil-free design eliminates oil management systemsfor improved compressor and system reliability.The oil-free design also eliminates the possibilityof efficiency-robbing oil contamination ofheat-transfer surfaces.WME CompressorWhy magnetic bearing compressors arethe right technology for todayThe frictionless magnetic bearing compressor was developedto improve performance, reliability and reduce servicerequirements as compared with conventional centrifugalcompressor designs.The magnetic bearing compressor has a single rotatingcomponent – the compressor shaft – levitated on a magneticfield. This cushion results in the shaft not being in contactwith any other part of the compressor while operating. Thecompressor shaft is kept perfectly aligned in all directionsby sensors at each magnetic bearing providing real-timefeedback to the digital bearing control system. This cuttingedge magnetic bearing technology enables outstandingenergy efficiency and reliable, long-life operation.The industry leader in environmental solutionsDaikin is committed to sustainable practices as part of our corporate culture.We believe it is the right thing to do for our customers, our community, theenvironment and ourselves. As the global HVAC leader, Daikin has a uniqueopportunity to make a difference in sustainable initiatives and continue to lead theindustry in environmental solutions.Chiller protection for long-term viabilityThe compressor’s ability to protect itself from low powerquality, and to have controlled response in power losssituations, is a feature that enhances long-term compressorviability and reduces downtime. Magnitude chillers withRideThrough can often remain on-line through minor powerdisturbances. In extreme or extended power disruptions,Magnitude compressors are designed to regenerate powerfrom the spinning motor and feed that power back to thebearings and control system. This regenerative power modeallows the compressor shaft to coast down and gently reseatonto touchdown bearings.Performance to save you millions of dollarsover the life of the chillerThe Daikin Magnitude magnetic bearing centrifugal chilleris the most energy efficient chiller in its size range with partload performance as low as 0.29 kW/ton IPLV.This amazing chiller technology has been proven effective inthousands of installations around the world. And it’s up to40% more energy efficient than standard centrifugal chillersand can save more than 4 million over the life ofthe machine.

Flexibility to design.What the owners of Daikin Magnitude chillerssay about their unitsJohnson County officebuilding in Olathe, KansasWe save 57% on energy costs comparedto a similar county office building down theroad. And with the high performancemagnetic bearing chiller as part of our system,we earned LEED Gold certification fromthe U.S. Green Building Council.Neil Angrisano, AIA, Deputy FacilityManager for Johnson County Photography by Brad FeinkopfSarasota BradentonInternational AirportSarasota, FloridaThe 500-ton variable speed magnetic bearingchillers will provide the airport with anelectrical consumption savings estimated to be30%. The new chiller technology also extendsthe chiller life, reduces annual maintenancecosts, improves controls of the chiller toweroperation, and is LEED qualified.Robert Mattingly, Vice President ofOperations and Maintenance

Northbrook Junior High Schoolin Northbrook, IllinoisWe were sold on the quiet operation of thechillers because the plant is located next tothree classrooms. The 18% reduction inenergy costs with the magnetic bearingchillers helped us earn an Energy Star School rating from the U. S. EPA after ourmechanical system modernization.Russ Jensen, Director of Buildings andGrounds for Northbrook School District 28McNamara Alumni Center atthe University of Minnesotain MinneapolisThe compact design of the chiller worked inour very tight design. Because the unit is soquiet we could avoid installing ahousekeeping pad typically used to isolatesound, thus greatly reducing the weight andphysical footprint.Jon McCombs, Operations Manager,McNamara Alumni Center

Flexibility to design.Ideal for retrofit and replacementThe compact size of the Magnitude chiller makes it ideal for retrofit and replacement installations. In addition, the space thatwould have been used for equipment can now be put to more productive use in the facility. Most models can easily fit throughdouble width doors without any disassembly. Even the most challenging access projects can be accommodated using our factorydisassembly option.Typical 290-ton unit83.9”(2131 mm)Stacked shell smaller footprint169.1”(4295 mm)47.2”(1199 mm)Service and maintenance savingsBecause the Magnitude magnetic bearing chiller hasfewer moving parts, requires no oil, nor oil-circulationequipment, it therefore requires less maintenance andservice. With oil removed from the system, maintenancetasks such as oil samples, oil changes, oil filter changes,oil disposal and leaks from shaft seals are eliminated.The results are reduced operational costs andmaintenance savings each and every year!Over the life of the equipment - approximately 20to 25 years - the total maintenance savings could besignificant. Savings an owner would realize dependon maintenance practices, age and efficiency of otherequipment, energy prices, etc.Operator training for maintenance and operation of Magnitudechillers is available from the Daikin Learning Institute.

A short-term power loss can happen during power interruptions, brown-outs or utility switching operations.With RapidRestore and RideThrough technology your Magnitude chiller can restart as fast as 43 seconds after power is restored.For chillers with Daikin’s unique RideThrough technology, the compressor shaft may never even come to a complete stop beforere-synchronizing with the VFD when power is restored. In addition, the Fast Loading option can restore 80% load cooling capacity inless than 75 seconds. So your critical cooling is restored before it’s missed.
