The world leader in oil-free chiller efficiency
The Smardt Chiller Group was established to maximize the
customer benefits of the Turbocor oil-free centrifugal compressor technology in chiller performance. Driving whole life costs of
ownership way down, your Smardt chiller saves you money, year
after long year, while reducing your carbon footprint and making
a major contribution to the future of the planet. Working with the Turbocor technology longer than any other HVAC manufacturer in the world, the Smardt Chiller Group has developed a lead in performance and reliability which translates into major benefits for owners – and the environment.
Global reach, single focus
Smardt (founded in Montreal, Canada in 2005 to focus on oil-free centrifugal chillers)
and PowerPax (founded in Melbourne, Australia in 2000 as a
specialist heat-exchanger group) , joined forces during 2005 to form the Smardt Chiller Group.
After several years of rapid growth, a new Smardt factory was
opened in Plattsburgh, New York in 2010, and a sales and
service operation opened in Singapore. In 2011, Smardt was
joined by the well-known OPK Klimatechnik business in Stuttgart,
Germany – an outstanding European pioneer in oil-free centrifugal
technology. And early in 2012, Smardt’s China manufacturing
operations will open in Guangzhou, Guangdong.
The heart of every Smardt chiller is its Turbocor oil-free centrifugal
compressors, which integrate rugged magnetic bearings systems
with variable-speed drive, high-efficiency centrifugal compression
and on-board digital electronics to achieve a revolutionary leap,
a quantum leap, in part-load energy efficiency.
A quantum leap in energy efficiency
All Smardt chillers, whether water‑cooled or air‑cooled, are
designed to optimize the performance of oil-free centrifugal
compressors from Danfoss Turbocor Compressors Inc. These use
oil-free magnetic bearings and variable-speed drives to deliver
better IPLV efficiencies than conventional oil-lubricated centrifugal,
reciprocating, scroll and screw compressors. They are also highspeed
– up to 48,000 rpm, very compact, very quiet, rugged
and reliable. Power factor is a high .92.
Proprietary magnetic bearings replace conventional oil-lubricated
bearings, eliminating high friction losses, mechanical wear and
high-maintenance oil management systems to deliver energy
savings of 35 percent and more over conventional chillers
while ensuring long-term reliability. Over 90,000 magnetic
bearing machines are operating in the field, mainly in high-end
vacuum pumps and CNC spindles – any innovation risk with this
component technology has been long overcome.
Turbocor’s one main moving part (rotor shaft and impellers)
is levitated during rotation by a digitally controlled magnetic
bearing system. Position sensors at each magnetic bearing
provide real-time feedback to the bearing control system, 120
times each revolution, ensuring constantly centered rotation.
Decades of development
The Smardt engineering team, many with long experience actually
developing the original Turbocor compressor technology, came together
to bring a definitive high-performance range of water-cooled
and air-cooled oil-free centrifugal chillers to the market, and to
make sure each Smardt chiller saves its owners money – money
in operating costs, money in maintenance costs, money because
of high reliability and redundancy which practically removes
mechanical risk altogether.
Algorithms used in all Smardt chiller controllers further enhance the
intelligence built-in to the compressor – achieving further efficiencies
across each compressor’s operating map, and further, optimizing
each compressor’s intrinsic part-load efficiencies in delivering
integrated chiller efficiencies that are currently unmatched.
