Scroll Compressor
The scroll compressor is ideal in applications where noise is a factor thanks to its low noise and
vibration. The compressor may be located on either the right or left side of the unit to make it
easier to service dual installations.
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.
Controls
For the highest levels of reliability — and to minimize site downtime — critical shelters can be
equipped with two Liebert InteleCool® 2 units and an autochangeover system that balances
runtime and automatically switches from one unit to another unit if required.
Swift, Simple Installation
Economizer Option
However you configure the Liebert InteleCool 2, it comes
from the Liebert factory wired, piped, charged with R-407C
refrigerant and factory-tested as a complete system. Each
standard unit is shipped with a Nationally Recognized Testing
Laboratory (NRTL) listing. If the wall openings and electric
service are in place, the Liebert InteleCool 2 can be installed
in as little as 30 minutes.
The Liebert 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.
Installation time is minimized
with Liebert InteleCool2’s
self-contained packaging.
Industry-standard
evaporator supply and
return openings allow the
unit to be placed quickly.
No Economizer
When outside
temperatures
are warmer than
the inside air, the
Economizer is
closed and indoor
air is recirculated
to maintain
proper cooling.
Full Economizer
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.
Modulated
In Modulated
mode, the
Economizer
draws cool
outside air and
recirculates indoor
air, reducing
compressor
run time.
