Emerson Network Power, in line with its total
commitment to intensive research and development and in order to
meet the ever growing needs of organisations for conditioning in
technology and data centres, has expanded its precision cooling
range with the introduction of Liebert HPC Chillers. The first to
appear is the Liebert HPC-L, an innovative family of air-condensed
water chillers featuring over 60 models, 4 noise emission versions,
two ecological coolant types, and power ratings from 700 to 1600 kW.
Characterized by high performance and compact dimensions, Liebert
HPC-L meets all energy saving and environmental protection demands.
At its core, the system is equipped with two semi-tight screw
compressors that ensure high reliability and excellent performance
not only at full load, but also when running at partial load. The
key strength of Liebert HPC-L is the lack of vibration, combined
with very low noise, which makes it ideal for urban areas subject to
strict acoustic pollution regulations.
Liebert HPC-L is available with incorporated freecooling module
that, utilizing cold external temperatures in the winter season to
cool water, provides for significant energy saving by avoiding the
operation of compressors.

This version is particularly suitable for the conditioning of
datacenters, where there is a constant search for solutions to
reduce total costs of operation (TCO). The new chiller family can
also optimize its energy saving capacity through Supersaver, which
reduces system energy consumption by combining the chiller’s logic
and set point with the logic and set point of Emerson Network Power
internal conditioning units. Energy saving is significant in terms
of environmental protection, as it results in the reduction of CO2
emissions from the equipment.
The chiller units of the new range are provided with a control that
allows temperature and pressure thresholds, as well as unit
functions, to be programmed through a patented Hirobus system.
The control can also communicate with other chiller units via LAN,
so as to optimize operation and show all operating parameters,
alarms and temperature history through a graphical display. Finally,
the units can be connected to higher-level control and supervision
systems, in order to issue SMS to signal system alarms (SMM),
monitor and maintain the system remotely (Hirovisor IP software) and
integrate the units into the most popular global management systems
like MOBDUS, LONWORK, SNMP.
