(2,1)IntroductionWorld’s Most Efficient Lowest Emissions ChillerI n g e r s o l l Ra n d E c o W i s e Po rt f o l i o — Trane has always taken a leadership position inenvironmental stewardship without compromising efficiency, reliability or safety. CenTraVac chillers are among the Trane products within the EcoWise portfolio and can operate with either R123 or next-generation refrigerants R-514A or R-1233zd, both featuring ultra-low GWPs of lessthan two. For more information, visit: trane.com/ecowiseE n v i r o n m e n t a l Pr o d u c t D e c l a r a t i o n — The entire CenTraVac chiller portfolio has earnedproduct-specific Type III Environmental Product Declaration (EPD) verification, the firstcommercial chiller in the world to provide this documentation. This EPD substantiates ourenvironmental claims regarding chiller performance and documents conformance with thestringent third-party certification requirements of the International Standards Organization (ISO)and verified by Underwriters Laboratories in accordance with ISO 14025.S t a n d a r d o f E x c e l l e n c e — Trane found that the straightest path to achieve the highest efficiencywith the best reliability is through simplicity of design. The CenTraVac chiller has only oneprimary moving part—a single rotating shaft supported by two bearings. This direct driveconcept minimizes the chance of failure by reducing the number of critical parts—no gear boxes,couplings, extra shafts, or shaft seals.E c o n o m i c a l l y a n d E n v i r o n m e n t a l l y So u n d — The CenTraVac chiller has a proven track recordas the world’s most efficient, lowest emissions chiller. It is selectable at an unmatched efficiencylevel of 0.45 kW/ton at standard AHRI conditions. The full load efficiency levels of CenTraVacchillers are simply the best available, averaging at least 13.5 percent better than the next bestcentrifugal chiller available today.L o w e s t Re f r i g e r a n t E m i s s i o n s — The key to the highest energy efficiency and lowest leak rate isuse of the low pressure refrigerants. CenTraVac chillers are designed to be leak-tight, deliveringthe industry's lowest documented refrigerant leak rate—less than 0.5 percent annually versus theindustry-accepted rate of 2.0 percent. We are so confident in our ability to keep the refrigerantinside our CenTraVac chillers, we back each one with a Leak-Tight Warranty—the first offered byany HVAC manufacturer.E a rt h W i s e S y s t e m D e s i g n — This high-performance system design approach reduces firstcost, lowers operating costs, and is substantially quieter than traditional applied systems. Centralto the design are low flow, low temperature, and high efficiency for both airside and watersidesystems, along with optimized control algorithms for sustainable performance. TracerAdaptiView controls provide the system intelligence required to manage the performance anddocument the benefits. Smaller equipment and ductwork means supplying less airflow at coldertemperatures and enables quieter operation. This also reduces relative humidity in the building,improving indoor air quality. Compared to conventional designs, an EarthWise chilled watersystem reduces the total cost of ownership by lowering installation and operating costs.

(7,1)General InformationLocal SupportThe performance and reliability of CenTraVac chillers is backed by a team of knowledgeableengineers, HVAC systems specialists and technical professionals. Your local Trane team will seeyou through the entire chiller bid process, from building analysis to equipment specification andthrough installation and commissioning.Custom Built UnitEach CenTraVac chiller is custom built to meet your specific project requirements, optimizing theconfiguration based on design parameters such as full- and part-load performance and watersidepressure drops.ISO 9001:2008 CertifiedThe quality management system used by the Trane CenTraVac chiller manufacturing facility is theISO 9001:2008 Standard. This standard documents office, manufacturing, and testing proceduresfor maximum consistency in meeting or exceeding customer expectations. ISO 9001:2008requires extensive documentation on how quality assurance activities are managed, performed,and continuously monitored. Included in the system are verification checkpoints from the timethe order is entered until final shipment. In addition, product development is subjected to formalplanning, review, and validation.Certified AHRI PerformanceCenTraVac chillers are rated within the scope of the Air-Conditioning, Heating & RefrigerationInstitute (AHRI) Certification Program and display the AHRI Certified mark as a visualconfirmation of conformance to the certification sections of AHRI Standard 550/590 (I-P) andANSI/AHRI Standard 551/591 (SI). The purge is rated in accordance with AHRI Standard 580.The applications in this catalog specifically excluded from the AHRI certification program are: Free coolingLow temperature applications (below 36 F [2.2 C]), including ice storage60 Hz chillers larger than 3000 tons (10551 kW) and/or greater than 15000 volts50 Hz chillers larger than 3000 tons (10551 kW) and/or greater than 15000 voltsHeat recovery and heat pump ratingsAuxiliary condenserGlycol and brinesDistrict CoolingTrane Adaptive Control algorithms and the multi-stage design allow all CenTraVac chillers todeliver low leaving chilled water temperatures (e.g., 34 F [1.1 C]) without the use of glycol orother freeze inhibitors. This reduces the cost of delivering cooling capacity over long distances.Pre-engineered CenTraVac thermal storage systems extend the chiller’s exceptional reliability tothe rest of the district cooling plant.Turbine Inlet CoolingTrane chillers are frequently used in conjunction with combustion turbines to increase the powercapacity, efficiency, and life of the turbine. Turbine inlet cooling can eliminate the need for inletwater spray to reduce NOx emissions. With turbine inlet cooling, plants can delay or even avoidthe need for additional turbines because more capacity can be obtained from existing turbines.CTV-PRC007M-EN7

(8,1)General InformationCenTraVac Chiller PortfolioElevated Chilled-Water Temperature ApplicationsThe Series L CenTraVac chiller (model CVHL) is a direct result of the Trane commitment toprovide the right technology for the right application at the right time.Because industrial processes and data center applications have unique cooling requirements, theSeries L chiller features optimized compressor and drive technology to deliver 60 F–70 F (15.6 C–21.1 C) chilled water with up to 35 percent better efficiency at full-load and off-design conditions.Premium Efficiency Chiller for Small SpacesThe Series S CenTraVac chiller (model CVHS) is an ideal solution for any low-tonnageapplication, especially retrofits and replacements. This compact chiller was designed to fitthrough standard double doors and features a bolt-together design for disassembly when accessto the mechanical room is even tighter. While smaller in size, the CVHS model continues todeliver the high efficiency, proven reliability, and ultra-quiet operation that Trane centrifugalchillers have provided for more than 75 years.8CTV-PRC007M-EN

(9,1)General InformationThe Ingersoll Rand Climate CommitmentNext-Generation RefrigerantsTrane has always taken a balanced approach to selecting refrigerants, considering factors such assafety, sustainability, efficiency, reliability and overall lifecycle impact. Expanding the CenTraVacportfolio to operate with either R-123 or with one of two low pressure next-generationrefrigerants (R-514A or R-1233zd) enables Trane to continue this commitment as the industryevolves through its next refrigerant transition, from HCFCs and HFCs to next-generation, lowGWP refrigerants.Effective immediately, CenTraVac chillers are available with either R-123 or R-1233zd (CVHH &CDHH), a next-generation refrigerant with a GWP of one. Classified as an “A1” refrigerant perASHRAE Standard 34, R-1233zd is one of the few nonflammable olefin options available today.In 2017, the CenTraVac portfolio will also include the option of R-514A, another next-generationrefrigerant with a GWP of less than two.Low pressure refrigerants have been a key element of the CenTraVac chiller design dating back tothe very first Trane centrifugal in 1938. These new models continue the tradition offering a lowpressure, leak-tight chiller that delivers best-in-class efficiencies.CTV-PRC007M-EN9

(10,1)General InformationBenefits of Low PressureTrane CenTraVac chillers feature a time-tested and proven low-pressure design utilizingenvironmentally friendly refrigerants, R-123, R-1233zd, and R-514A. They provide the safety oflow pressure with continued product enhancements in leak-tight design. Consider the benefits ofa low pressure CenTraVac chiller versus medium pressure machines:Table 1.Operating pressure comparison at AHRI conditionsEvaporatorCondenserMonitoring of leak rateTypical PressuresEvaporator: 38 F (3.3 C)Condenser: 100 F (37.8 C)(a)10Low PressureMedium Pressure Always at negative pressure Operates at positive pressure Air leaks inward Refrigerant leaks outward at moderate rate Refrigerant lost: (# air leak in) x purge efficiency(a) No refrigerant loss into equipment roomRefrigerant loss is difficult to know,performance is degraded Refrigerant loss is into equipment room Always at high positive pressure In the event of a leak, refrigerant would leakoutward at a very high rate Only ways to monitor leak rate on mediumpressure chiller are: Usually at neutral to negative pressure duringinactivity (air might leak inward) At slightly positive pressure during operation In the event of a leak, refrigerant could leakoutward, but at a very low rate Unit purge is able to continuously monitor inleakage with the run meter, whether the chiller ison or off. Refrigerant monitor as required by ASHRAE. Purge can be connected to a building automationsystem for notification of increased purgeoperation (in-leak). Similarly, the BACnet module allows the refrigerant monitor to beconnected to the building automation system.R-123Evaporator: -9.2 psig (-63.4 kPaG)Condenser: 6.1 psig (42.1 kPaG)R-514AEvaporator: -9.5 psig (-65.4 kPaG)Condenser: 5.3 psig (36.3 kPaG)R-1233zdEvaporator: -6.6 psig (-45.8 kPaG)Condenser: 14.4 psig (99.3 kPaG)–periodic leak checks–purchase refrigerant monitor Refrigerant monitor as required by ASHRAE. Typically, the only time a leak is detected on amedium pressure chiller is during springstartup. This means that a chiller whichdevelops a leak in the summer may leakcontinuously until the following spring.R-134aEvaporator: 33.1 psig (228.5 kPaG)Condenser: 124.2 psig (856.0 kPaG)R-513AEvaporator: 37.6 psig (259.0 kPaG)Condenser: 130.7 psig (901.2 kPaG)R-1234zeEvaporator: 20.8 psig (143.1 kPaG)Condenser: 89.9 psig (619.8 kPaG)Trane purge efficiency does not exceed 0.02 units of refrigerant per unit of air.CTV-PRC007M-EN

F l a s h E c o n o m i ze r — CenTraVac chillers leverage a multi-stage design with two or threeimpellers, making it possible to flash refrigerant gas at intermediate pressure(s) between theevaporator and condenser. This feature increases chiller efficiency up to 4.5 percent for two-stagechillers and up to 7 percent for three-stage chillers.D . R e f r i g e r a n t C o o l e d M o t o r — All Trane CenTraVac chiller motors are cooled by liquidrefrigerant surrounding the motor winding and rotor. Using liquid refrigerant in uniform lowtemperatures prolongs motor life, as to open designs. As an additional benefit, motor heat isrejected out to the cooling tower, helping to keep the equipment room at a desirabletemperature.E . L o w Pr e s s u r e D e s i g n — Low pressure refrigerants have been a key element of the Tranecentrifugal chiller design since 1938. Backed by the Trane 0.0% Leak Tight Warranty, CenTraVac’stight vessel low-pressure operation minimizes the chance for outward refrigerant leaks.F. P u r g e Sy s t e m — The high efficiency purge system is designed with automatic regenerationcapability. When the filter senses that it is full, the regeneration cycle begins, and reclaimedrefrigerant is automatically returned to the chiller, keeping the purge’s productivity at its peakwithout the need to exchange carbon canisters. The CenTraVac chiller purge system hascapability to run even when the chiller is turned off.G . D i r e c t D r i v e L o w – S p e e d C o m p r e s s o r — The exclusive CenTraVac compressor has only onemoving part supported by just two bearings, providing reliability through simplicity of design.The low-speed, direct-drive design not only gives the CenTraVac compressor the most reliableand efficient operation, but also the lowest sound and vibration levels in the industry. Thisfeature also eliminates the need for costly jacketing and energy-wasting liquid-refrigerant soundattenuation.CTV-PRC007M-EN11

(12,1)General Information0.0% Leak-Tight WarrantyTerms and ConditionsThe Company warrants for the lesser of 60 months from initial start-up or 66 months from date ofshipment that the CenTraVac chiller will be leak-tight against refrigerant loss or the Companywill furnish replacement refrigerant (the limited “Leak-Tight Warranty”). The limited Leak-TightWarranty covers CenTraVac chillers (models CDHF, CDHH, CVHE, CVHF, CVHH, CVHL, and CVHS)installed in the United States and Canada that ship from the factory in La Crosse, Wisconsin,September 1, 2004 or later.

No liability whatever shall attach to the Company until appropriateactions (acceptable to Company) have been taken to eliminate the source of the leak.If the chiller is placed under a comprehensive Trane service and maintenance agreement (Trane“Select Agreement” or better) prior to the expiration of the standard Leak-Tight Warranty, theprotection against refrigerant loss shall continue under the Trane Select Agreement for as long asan active Trane Select Agreement remains in effect without interruption.If a 10-Year Parts, Labor and Refrigerant Warranty was purchased for the chiller and the chiller isplaced under the Trane Select Agreement (or better) prior to the expiration of the 10-Year Parts,Labor and Refrigerant Warranty, the protection against refrigerant loss shall continue under theTrane Select Agreement for as long as an active Trane Select Agreement remains in effectwithout interruption.Any further warranty must be in writing, signed by an authorized representative of the Company.NOTWITHSTANDING ANYTHING TO THE CONTRARY, IN NO EVENT SHALL THE COMPANY BELIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES EVEN IF A PARTY HAS BEENADVISED OF SUCH POSSIBLE DAMAGES OR IF SAME WERE REASONABLY FORESEEABLE ANDREGARDLESS OF WHETHER THE CAUSE OF ACTION IS FRAMED IN CONTRACT, NEGLIGENCE,ANY OTHER TORT, WARRANTY, STRICT LIABILITY, OR PRODUCT LIABILITY.Integrated Rapid RestartN o t e : Restart times are based on chillers with a electromechanical speed starter. Restart timeswith a Trane Adaptive Frequency drive will vary. Contact your local Trane accountmanager for more information.A loss of cooling capacity can be costly, which is why CenTraVac chillers are designed tointegrate seamlessly with uninterruptible power supplies (UPS) and have the shortest restarttimes in the industry.In the event of a power interruption, the chiller defaults to its rapid restart mode, optimizingelectrical and mechanical variables, including guide vane position. This not only helps the chillerget back online faster, but it also provides the least amount of load on your building’s electricalinfrastructure, which can make a big difference if your building has a backup generator.Even under extreme conditions, CenTraVac chiller restart times have been verified at as few as43 seconds, as shown in the following figure. Thanks to fast restart times like these, you cansubstantially minimize the risks of financially devastating damage to assets caused byoverheating due to power outages. Of course, the truest test of a chiller’s restart capabilities is theamount of time it takes to resume full-load cooling, and this is where the CenTraVac chiller reallyshines. An 80 percent cooling load can be achieved in less than three minutes after powerrestoration—your assurance that the cooling capacity your equipment requires is just a fewminutes away.12CTV-PRC007M-EN
