Redundancy To Secure Your Business

Availability

100% redundancy CW circuits

Dual CW circuits with double

power supply maximize

availability.

Flexibility

Simplified design layout:

power cables

condensate drain

supply/drain for humidifier

Secondary CW circuit can provideadditional cooling in the event of

increased heat loads

Low Total Cost of Ownership:

Reduced footprint compared to

two separate units

Lower investments in air-

conditioners

Lower cost for the installation

Liebert HPM R-type units are

dual circuit chilled water unitsfor business critical applications.

Equipped with two independent

chilled water circuits they are able

to take cooling fluid from two

independent sources.

The models are available in the

cooling capacity range 24 - 120

kW for each circuit; each equipped

with 3 or 2 Port valves. These units

provide additional security for your

critical environment. With primaryand secondary chilled water circuits

the units provide mandatory back

up in terms of cooling capacit y.

Liebert HPM Dual CW Circuit

Hydraulic System Schematic

Liebert HPM Dual CW Circuit

units are specifically designed

for buildings with primary and

secondary chilled water circuits.

A typical application is forpolyfunctional buildings where

a larger cooling source operates

during the day, serving offices,

technology and datacentres; while

at night when cooling is only

required for the technology and

datacentres we can use a smaller

chilled water source, maximizing

obvious energy savings.

iCOM - Keep it under control

Control

The sophisticated control logic of the

units offers several options to sat-

isfy the chilled water system require-

ments and valve management.

Parallel mode

The chilled water valve manage-

ment and positions are the same

for both CW circuits.

Safe mode

First circuit and valve managed

utilizing 70% of proportional tem-perature band, and then

second valve starts to open (Re-

quires same inlet fluid tempera-

ture on both circuits).

Alternate mode

With an external input to the iCOM

controller it is possible to manage

which of the two chilled water cir-

cuits / valves is duty and which is

standby.

In parallel and safe modes both CW

circuits can run together maximizingthe cooling capacity.
