    Why do Building Owners Purchase more Trane Chillers than any other Chiller? When choosing a centrifugal chiller, building owners look for a low total cost of equipment and high efficiency with minimal maintenance requirements. They also demand technology that will deliver exceptional performance over the life of the chiller, while ensuring the least environmental impact. That is why Trane EarthWise™ CenTraVac™ chillers are purchased more than any other chiller.

    Highest Efficiency • At least 13.5% more efficient than

    any other chiller • Energy-efficient compressor design

    with low-pressure refrigerant • Energy-saving options include oil-

    free cooling, thermal storage, heat recovery and variable-speed drives

    • The highest ful l- load eff iciency minimizes the electrical infrastructure required and reduces the impact of demand-based charges and real-time pricing during peak periods.

    • The highest part-load efficiency drive lower overall electrical consumption charges (kWh).

    • The best IPLV eas i l y exceeds ASHRAE 90.1 part-load efficiency requirements.

    Lowest Emissions • The only commercial chiller to earn

    an Environmental Product Declaration according to ISO 14025

    • Recipient of three awards from the U.S. Environmental Protection Agency

    • Capable of earning more LEED® credits than any other chiller

    Most Reliable • Only one moving part supported

    by just two bearings to minimize maintenance

    • Semi-hermetically sealed motor to lock out dirt

    • Refrigerant-cooled motor to protect against high temperatures

    • Extensive factory testing available to ver ify operat ion at specif ied conditions

    • Ten-year parts, labour and refrigerant- loss warranty available

    TranenewsletterDecember • 2013 1

  • Proven Technology • Direct drive for better reliability with

    no gears, transmissions or shaft seals • Multistage compressor for stable

    operation under all conditions • Low-pressure refrigerant for un-

    surpassed efficiency, reliability and documented near-zero emissions

    • Industry-leading control algorithms for reliable operation

    Technological superiority The Trane Series S™ CenTraVac chiller is innovation at its best. With numerous Trane patents in place and pending, new technologies enable its industry- leading efficiency, reliability and ultra- quiet operation, even at heavily loaded conditions. Quite simply, it is the most technologically advanced oil-free chiller in the world.

    Adaptispeed™ Technology The Trane Series S CenTraVac chiller features AdaptiSpeed™ technology: the integration of an all-new, specific-speed, direct-drive compressor with Trane exclusive Adaptive Frequency Drive AFD3. Together, they deliver best-in- class efficiency.

    Adaptive Frequency Drive AFD3 Designed to last the life of the chiller, the AFD3 consumes less energy at all operating points without the risk of incurring excessive demand charges during near-full-load operation. A true

    24-pulse design provides the harmonic solution to meet the requirements of IEEE 519, reducing harmonic distortion to less than 5% total demand distortion (IEEE). Unique in the industry, the AFD3 is a fully integrated variable-speed drive working with the motor and the Tracer AdaptiView™ unit controller to continuously optimize chiller efficiency through compressor speed and guide vane position.

    Proven Reliability Proven over a decade of field testing, the Trane Series S CenTraVac chiller includes multiple design features to prolong component life and reduce maintenance needs—including an advanced bearing system that will outperform any other oil- free system in the industry today. Hybrid Ceramic Bearing System offers a reliable oil-free solution without requiring backup bearings and complex electronics to address extreme operating conditions. The high-strength hybr id ceramic bearings have been proven through extensive field operation for more than ten years.

    ultra-quiet Operation Comfor t i s about more than just temperature; building occupants also expect a quiet environment. The Trane Series S CenTraVac chiller produces industry-leading sound levels-typically less than 75 dBA-making it perfect for sound-sensitive applications.

    Environmental stewardship Like all CenTraVac chillers, the Trane Series S chiller’s leak-tight low-pressure refrigerant design combined with its industry-leading energy efficiency make it the most environmentally sustainable chiller in the world, helping customers earn more LEED® credits. Direct-drive CenTraVac™ chillers are designed to use a low-pressure refrigerant. This means the chillers operate in a vacuum, which virtually eliminates leaks and enables near-zero emissions throughout their operational life. That is a win in terms of the direct environmental impact of the refrigerant, minimizing the Ozone Depletion Potential (ODP) and Global Warming Potential (GWP).

    Making Buildings Better for Life In fact, Trane is so confident in its ability to keep the refrigerant inside our CenTraVac chillers that we back each one with a leak-tight warranty for all CenTraVac chillers installed in the U.S. and Canada and extended for the life of the chiller when covered by a comprehensive Trane service agreement. Today’s Series S CenTraVac chiller contains more innovative solutions to boost performance and efficiency while maintaining higher levels of reliability and environmental sustainability than any other chiller on the market.
