LIEBERT INTELECOOL2

Product Specification Sheet

Features/Options
Self-Contained
All components are enclosed in the painted steel or optional
corrosion-resistant aluminum cabinet. The standard color for the
painted steel is tan, with optional colors available.
Space-Saving Design
Mounted outside the shelter to save valuable space.
Range of Capacities
Units are available in 1.5, 2, 3, 4 and 5 ton 60Hz models, and 3, 4
and 5 ton 50Hz models.
Compressor Options
A high-efficiency scroll compressor is standard on all models. It is
ideal in applications where noise is a factor because of its low
noise and vibration.
Optional Compressor Location
Evaporator Supply and Return Openings
Match industry standard dimensions.
Easy to Install
Wired, piped, charged with refrigerant and factory-tested as a
LIEBERT INTELECOOL 2
system to ensure trouble-free installation and startup.
1.5,
2, 3, 4 and 5 Ton Models
Outside Air Options
A fixed fresh air damper option allows for adding fresh air/pressurization. The Economizer option allows
for cooling using outdoor air when it is cool enough to meet the room conditions.
4 or 5 Ton Unit With 3 Ton Openings
Designed to replace 3 ton wall-mounted air conditioners using existing wall openings.
Telecom Package T-Pack
This configuration incorporates popular telecom options: low pressure switch, fan cycle control and low
pressure bypass. Many other component options are also available.
Control/Monitor Options
The Liebert Dual Unit Control thermostat can control two units and provides autochangeover control.
Other autochangeover control options are also available.
