High Capacity Models
Larger, integrated, scalable precison cooling
units maintain the benefits of a redundant and
packaged cooling design. Flexible fan locations
allow for some variable floor depths.
Air Side Economizer
Plenum mixer boxes allow efficient use of
outside air for cooling (when enthalpy of
outside air is less than indoor return air).
Liebert iCOM Controls
Advanced controls ensure superb efficiency
through teamwork, seperate fan and capacity
control, unit rotation and more.
EC Fans
Improved airflow performance and
efficiency. Energy savings of 20-30% over
traditional designs.
Intelligent Cold Aisle
Containment
Improved air management, energy efficiency
and capacity. In this design we deploy partial
containment with doors but no roof while
leveraging Liebert iCOM control.

Maximize the return
temperature at the cooling
units to improve capacity
and efficiency
Match cooling capacity and
airflow with IT loads
Utilize cooling designs that
reduce component power
Enhance data center

Applied Power Approach
Tier 2, Transformer-based Power with Busway Distribution
The power approach utilized in this scenario supports a Tier 2, 1.1 MW data center. Both the UPS and electrical distribution
configurations are optimized for efficiency, availability and capacity.
UPS Design:
Electrical Distribution Design:
Designed to be Tier 2 rated, utilizes one (1) utility transformer,
and one (1) main utility switchgear module. The UPS system
consists of four (4) 500kVA Liebert NXL UPS modules paralleled
into a bypass distribution cabinet in a distributed redundant
(1+N or distributed static switch) configuration. Backup power
generation is provided by two (2) 2.5MW generators paralleled
in (N+1) configuration.
The distribution design consists of six (6) 225kVA Liebert PPCs
which receive power from a UPS distribution panel board. Each
Liebert PPC powers three (3) 225A Liebert MB modular busway
systems to provide reliable, flexible power distribution. Final
power connections to the servers are performed in the rack
using Liebert MPX intelligent rack PDUs.

while still ensuring mission-critical availability. Using the
innovative equipment and industry-best practices that this
approach offers, you can avoid the costly expenses associated
with system failures and down times.
Did you know?
Average data centers experience 5.12 power outages
every two years
Outage duration averages 106 minutes
System recovery is estimated at 3 times the duration of the
outage (318 on average)
This means that on average, each unplanned outage
costs $507,000*.
