which can deliver significant energy and operating
cost savings during the equipment’s lifespan.
Mounted on top of racks running down the center
of the room, the Liebert XDV modules connect to
a Liebert XDC chiller, which circulates the refrigerant
through an air-cooled condenser on the facility’s roof
for heat removal.
Liebert XD flexible piping connects all components.
US Internet installed Liebert factory pre-fabricated
dis
tribution piping in anticipation of its projected
growth and dynamic operating environment. When
needed, additional Liebert XD cooling modules
can easily be added via quick-connect fittings on
the piping.
Carter says the flexibility of the Liebert XD system is
a key benefit. “In a colocation center, hot spots can
de
velop almost overnight. The plug and play nature
of the Liebert XD System allows us to adapt cooling
capacity on demand.”

A dynamic power infrastructure was equally critical
to the success of the project. “Power and cooling are
to a data center what an engine and tires are to an
a
u
t
omobile. You can’t run without both of them,”
Carter says.
The expanded power infrastructure brings distribution
closer to the rack to ensure sufficient connectivity for
ne
w servers while simplifying cable management. Fully

an
t ‘A’ and ‘B’ circuits connect to independent
utility power feeds and backup generators. Dual-
corded equipment connects to both circuits, allowing
continuous operation of equipment if one circuit fails.
In the event that either circuit loses utility power, an
Emerson Network Power ASCO ATS automatic transfer
switch manages the transfer of the critical load to the
emergency generator.
Power conditioning and distribution for each service
of incoming utility power (or two generators in case
o
f an outage or brown-out) begins with Liebert TVSS
surge protection units at the service entrances to
protect against transient split-second overvoltages

the TVSS, a Liebert Series 610 300 kVA UPS provides
12 minutes of clean, reliable backup power to each

“I’m completely comfortable staking my company
on Liebert equipment, engineers and trained
service personnel.”
