High Heat Density Solutions For Rack,

Spot And Zone Cooling

Mission-critical heat removal systems can

now be configured to target cooling directly

at hot spots. Unique equipment designs

also enable users to handle high heat loads

without consuming additional floorspace.

Data Center Cooling Solution

Starts With The Best

A Liebert DS Mission-Critical Cooling

System provides basic cooling, humidity

control and air filtration.

The Liebert XD

™

System Provides

Supplemental Sensible Cooling

For High Heat Density Racks

Or Zones.

Product Features Include:

Energy efficient.

Can cool more than 30kW per rack.

Pumped refrigerant solutions are ideal

for use around electronic equipment.

Minimal floorspace requirements.

Flexibility to accommodate various

equipment layouts.

Scalable – add or move cooling

modules as your needs change

without the need for an HVAC

technician.

Supplemental Sensible Cooling

Pumped refrigerant

technology is ideal

for use around

electronic equipment.

It operates at low

pressure in the piping

circuit and would

become a gas

at room conditions.

Use of pumped

refrigerant also

makes the system

very energy efficient

and it saves space

with smaller piping

requirements and

the ability to utilize

more compact heat

exchangers.

Liebert XD

™

Series Rack, Zone And Spot Cooling:

Flexible Configurations For Many Applications

Space-Saving

Solution That

Cools From

The Top

The

Liebert XDV

Cooling Module

mounts vertically

above or on the IT rack

enclosure, drawing

hot air from inside the

cabinet or from the

hot aisle. It then cools

the air and discharges

it down to the cold

aisle. This space-saving

solution requires zero

floor space. Available

with Smart Module

integrated control

board, for increased

module control and

monitoring.

A Chiller Designed

For Direct System

Configurations

The Liebert XDC

Chiller is a specially

designed indoor

unit that connects

directly to the

Liebert XD Cooling

Modules and

provides chilled

pumped refrigerant

circulation and

control. It ensures

that the refrigerant

is constantly above

the actual dew

point in the room,

eliminating concern

about condensation.

Available with several

heat rejection options.

The Overhead

Cooling Solution

The ceiling-mounted

Liebert XDO Overhead

Cooling Module

mounts directly above

the cold aisle. It draws

in hot air from the

hot aisle and then

discharges cool air

into the cold aisle

where the equipment

air inlets are located.

This energy-efficient

unit takes up no floor

space. Available with

Smart Module

integrated control

board, for increased

module control and

monitoring.

Pumped Refrigerant Approach

Pumping Unit

Designed

For Indirect

Configuration

Applications

When a building chilled

water system is

available, the Liebert

XDP with iCOM

Pumping Unit serves

as an isolating interface

between the building

chilled water system

and the pumped

refrigerant circuit. It

circulates refrigerant to

the XD Cooling Modules

at a temperature always

above the actual dew

point to prevent

condensation. Liebert

XDP features Liebert

iCOM controls,

enhancing system

reliability and flexibility.
