A REAL CHOICE FOR
TELECOM SHELTER PROTECTION
Cost Effective, Flexible Air Conditioning
For Unmanned Telecommunications
Shelters And Other Remote Structures
AIR CONDITIONING DESIGNED FOR TODAY’S
TELECOMMUNICATIONS SHELTER NEEDS
Even though they look the same on the outside, telecommunications shelters have very different requirements. Redundant city
shelters can be produced inexpensively. Suburban and country shelters usually require greater reliability. And those sited well
away from civilization need both high levels of reliability and remote communications capacity.
2
So why is it that shelter air conditioners are all the same?
They’re not, thanks to Liebert. The first name in protection for sensitive systems for more than 30 years,
Liebert has created the InteleCool® 2 shelter air conditioning system.
It’s not just a shelter air conditioner...it’s a custom-configured model that fits your exact needs and budget. Want
a bare-bones system at minimum cost? Consider the InteleCool 2, basic model. Want a top-of-the-line unit for that
vital remote shelter? Try the InteleCool 2, advanced system. Need a field replacement/upgrade of a 3 ton air conditioner
to 4 or 5 ton? Take the InteleCool 2 replacement/upgrade unit. Same name...very different shelter air conditioner.
In the next few pages, we’ll show you how to custom-configure an InteleCool 2 for every application.
Liebert Means Legendary Reliability
Liebert invented high-reliability, precision-controlled
air conditioning for computers and computer rooms
A Perfect Match For
Many Critical Applications
In addition to a wide range of telecommunications
more than 30 years ago. Today, the telecommunications
shelter applications, the InteleCool 2 can be

The InteleCool® 2 is designed with the flexibility to match the multiple protection
needs of today’s telecommunications industry. You pick the level of protection your
application requires and Liebert will configure an InteleCool 2 for you...
Basic Cooling
For shelters that are less critical and located close to service capability,
minimum seasonal air conditioning is usually sufficient. Depending on the
application, single or redundant units may be used. A simple remote
monitoring capability may also be added.
Critical Shelters
Shelters with highly sensitive equipment and limited site access must keep
operating no matter what. These sites may require dual units, high-reliability
components such as a scroll compressor, energy saving capabilities such
as an economizer, heating, remote monitoring and switchover control.
The InteleCool 2 T-Pack is designed for these types of common
telecommunications shelters. This package includes the basic InteleCool 2
system with all of the most popular options including high and low pressure
switches, fan cycle control and low pressure bypass.
Special Locations
You don’t always have a choice as to where to place a telecom shelter.
It may be located in an urban environment where noise, appearance and
other factors are important. Or it may be miles from nowhere on the side
of a mountain—making absolute reliability an important requirement.

Step 3: Compressor
The InteleCool 2 offers a choice of compressors to match your specific reliability needs. A rugged
hermetic compressor is standard on the 1.5, 2 and 3 ton units. For applications requiring the
highest reliability and lower energy use, a scroll compressor is also available as an option on the
Almond
1.5, 2 and 3 ton sizes and is standard equipment on the 4 and 5 ton capacity models. With fewer
moving parts and continuous compression, the scroll compressor is 14% more efficient than
hermetic units. It operates at an EER level of 11.3 — one of the highest in the industry. The scroll
compressor is also ideal in applications where noise is a factor thanks to its low noise and vibration.

Compressors can also be located on either the right or left side of the unit to make it easier to service dual installations.

Step 5: Economizer Option
The InteleCool 2 can be equipped with an economizer
system that uses modulating dampers to draw in
filtered, outside ambient air for cooling when the exterior
temperature drops below a pre-set level. These outside air
temperature settings are field adjustable. The economizer
saves energy and reduces component wear.

Step 4: Fresh Air Damper

If required by your application, this
feature allows the introduction of
outside air into the shelter by means
of a field-adjustable damper.
Step 6: Controls
The high quality thermostat senses
ambient temperature and compares it
to your predetermined requirements.
For the highest levels of reliability —

When outside
temperatures are
warmer than the inside
air, the Economizer is
closed and indoor air
is recirculated to
maintain proper cooling.
The Economizer takes
advantage of low
outdoor ambients,
drawing on this cool
air to maintain indoor
temperatures. The
result is cooling at
lower energy costs,
also saving wear on
components.
In Modulated mode,

and to minimize site downtime —
critical shelters can be equipped with
two InteleCool 2 units and an
autochangeover system that balances
runtime and automatically switches
from one unit to another in case of a
system failure. Dual operation can be
accomplished with either the Dual
Unit Control thermostat or the Tele2®
control and monitoring system.

and alarm dispatch capability from our Columbus, Ohio,
