Skanska and INERTECH Achieve Lowest PUE to Date
NEW YORK --(Business Wire)--
Mission Critical Center of Excellence, along with technology and
manufacturing partner INERTECH,
LLC, announced today its patent-pending eOPTI-TRAXTMsystem
achieved a record-setting 1.012 mechanical Power Utilization
Effectiveness (PUE) reading in repeated testing.
The tests were conducted by a leading research team from the University
of Maryland's Department of Mechanical Engineering.
This unprecedented low reading leads the data center industry, where the
average mechanical PUE for a facility is 1.4 to 1.6 and greater.
"We test systems from manufacturers across the globe," said Dr. Ming
Zhang, a researcher from University of Maryland who led a team of
third-party researchers in performing the tests. "The efficiency,
robustness and automation of the eOPTI-TRAX system are truly unique.
These PUE readings are at least four times more efficient than simply
moving air under ideal conditions, and much more efficient than
traditional systems designed to the same level of reliability."
Additionally, test results reveal the energy efficiency was nearly the
same from full capacity down to 30 percent load, solving a problem that
has long plagued the data center industry: how to achieve a low PUE and
maintain efficiency under lightly loaded IT conditions as well as
extreme dense loads.
"Today's breakthrough not only has major data center and IT
implications, but also promises to save the business community millions
of dollars in missio critical energy costs alone," said Jakob
Carnemark, Senior Vice President of Skanska's Mission Critical Center of
Excellence. "We are now able to build agile IT infrastructure deployed
as needed, and guarantee the PUE under fluctuating load conditions."
"This test dramatically ends the air debate," said Earl Keisling, CEO of
INERTECH. "The spread in efficiency multiplies significantly in warmer
climates. Moreover, we can handle densities up to 50 kW per rack and
also eliminate server fans,saving more than double the system's energy
use to achieve net-zero added energy."
Keisling further elaborated: "Now that we are in full production and
shipping to clients, we continue to be amazed at what this technology
has accomplished and its better-than-predicted performance. The robust
system's components require no scheduled maintenance and are fully
automated. What's more, the system uses 80 percent less water than
traditional systems and can even be configured to use no water, saving
millions of gallons of water."
The test aisle was configured with dynamic loads including ramping rack
loads up to 32 kW per rack. The system was able to fully handle up to a
93 degree delta T and maintain a controlled environment with a 77 degree
aisle temperature while introducing no outside air. The PUE includes all
loads to fully cool the system. The system was able to maintain less
than two percent total mechanical overhead all the way down to 30
"Businesses are starting to move away from traditional procurement
models in order to drive innovation in the supply chain," Carnemark
said."As this trend continues to emerge, the job of the Chief
Information Officer has evolved to assume a much more active role in the
procurement of infrastructure. Now more than ever, the CIO is focused on
developing strategic partnerships similar to their approach in
applications allowing opportunities for breakthrough innovation."
