Featu res and Ben efits
Reliability and Low Environmental Impact
Reliability
The Liebert HPC - S 017- 032 series is equipped with four hermetic scroll
compressors, which represent state- of - the - art technology in this sector.
They have been designed and optimized for air- cooled water chillers within
air conditioning applications.
The high volumetric efficiency ensures excellent performances of the Liebert
HPC- S 017- 032 units at full load operation and especially at partial load,
thanks to the interlaced- circuit design of the condenser coil.
Extremely low noise operation and the absence of vibrations aid the installa-
tion of the unit in city sites requiring strict noise limits.
The wide operating range, bearing lubrication, component oversizing, ab-
sence of vibrations and few moving parts, together with the resistance to liquid
slugging and compressor electronic control integrated with the machine mi-
croprocessor enhance the well- known characteristics of operating reliability
and long life typical of this compressors type.
Furthermore, Liebert HPC - S 017- 032 tandem - compressor design with
two independent refrigeration circuits allows maximum internal redundancy and thus system reliability.
All Liebert HPC - S 017 - 032 units are run tested at the factory before shipment.
High outdoor temperature
The oversizing of heat exchangers and the wide operating range of the scroll compressors permit the
use of Liebert HPC - S 017- 032 units in high temperature environments as well, up to 46° C at 100%
full load.
Resistance to liquid slugging
The robust design of the scroll compressors can tolerate/withstand amounts of liquid refrigerant that
would severely damage reciprocating compressor valves, piston rods and cylinders.
Low Sound Emission
The Liebert HPC- S 017 - 032 series is characterized by unrivalled low sound emissions, in particular
the models of the ”G” version equipped with the “Quiet” kit (Digit 7=2 and 11=4).
Compressors supported on anti- vibration mounts and positioned in a closed compartment, common
to all versions; fans specifically designed to reduce the sound emissions and a special compressor cas-
ing on unit configuration.
All the models are equipped with stepless fan speed control, (optional without freecooling), thanks to a
special algorithm on the iCOM board, the fan speed could be kept to the minimum.
It is possible to reach even lower sound emissions with EC fans (electronically commutated fans), which
especially during reduced speed operation, allow noise levels around 50% lower than the values meas-
ured at the same conditions with traditional fans.

Unequalled Efficiency and Energy Saving
The use of hermetic Scroll compressors of the latest generation; plate heat exchanger evaporators selec-
ted for R410A application; aerodynamic profiled blade fans with high efficiency nozzles; large surface
condenser coils ensure the achievement of unequalled efficiency figures.
Freecooling Module
The “Freecooling” execution allows Liebert HPC- S 017- 032 to take advantage of low outdoor air tem-
peratures in the water cooling process in order to save energy, by avoiding compressors running.
A three - way valve arrangement permits the coolant to be diverted via the additional heat exchangers
before being fed into the cooling evaporator.
This means that even if the outside ambient temperature is not low enough to provide the complete cool-

ing load, a significant contribution to the running costs of the system can be made whenever the ambient
temperatures falls below the coolant inlet temperature.
Reduced space requirements in comparison with a conventional chiller plus a dry- cooler, are obtained
through the “Freecooling” execution’s compact design and the reduction of the compressors working
hours offers exceptional saving both in the long and short term.
The different strategies adopted by the proprietary microprocessor control in managing the various com-
ponents, fans - compressors - regulation valves, and operating modes, mechanical and/or free cool-
ing, together with the compressors’ partialisation ensure typical energy savings greater than 30%.

Seasonal Efficiency
The ”Freecooling” execution finds its best application in combination with the “Supersaver Evolution”
system which regulates the coolant temperatures according to the variation of the thermal load, increas-
ing the numbers of hours during which free cooling is possible.
The percentage of energy saving can thus be greater than 35%.

Integration with Indoor Air Conditioners
Supersaver Evolution System
A special working mode can be set up in combination with Vertiv HPAC indoorunits to obtain the
”Supersaver Evolution” system, that enhances the energy saving capabilities and thus op-timizes the
SEER (Seasonal Energy Efficiency Ratio) of the system.
Through @connectivity the information on the cooling needs of the air conditioners is available to the
Liebert HPC - S 017 - 032 units, that will manage their resources (compressors and free cooling) in the
most efficient way in order to save addition-
al energy.
This solution does not require any
modification, mechanical or
electrical thus avoiding ad-
ditional components
and regulation al-
gorithms which
could undermine the
reliability of the sys-
tem.
@ Connectivity
When the room units
are equipped with
thesametypeof
con-trol system
Vertiv (iCOM and
CDL), it is
possible to maximize
the energy savings and im-
prove the total operation man-
agement.
The solution is @connectivity,
which is a highly sophisticated way to let the system components (the Air- Conditioners as well as the
Liebert HPC - S 017 - 032 units, Chiller and Freecooling executions) talk to each other.
The @connectivity plug- in allows the setting of different working modes for different situations, such
as:
Dhigher water temperature in low load operation (energy saving);
Dlower water temperature for dehumidification (better performance);
Dspecial ”night” Setpoint (energy saving & noise reduction);
Dlower water temperature if one or more Air Conditioners fail (keep capacity in emergency situations);
D...andmuchmore!
To ad d t he @connectivity to your system, it is simply necessary:
To build up Hironet connection between the room units and the Liebert HPC - S 017 - 032 units. The
network can be only 1 (if the distance and the number of units allow this) or it can be split in several net-
works.
On @connectivity it is possible to define the rules that you want your system to respect.
It will be then up to the web capabilities to allow the view and control of your system from any PC of your
Local area network (provided that the @connectivity PC is connected on the LAN) or even if you have
a connection to Internet and your system is open to external access, you will have the possibility to view
and control your system via Internet
Flexibility: Hydronic Module
In order to match different kinds of installations and applications, Liebert HPC- S 017 - 032 units are
available with a hydronic module, which can be adapted/adjusted depending on the specific requests.
Based on this philosophy, the units can be equipped with everything that is needed for the correct install-
ation and, in this way, reduce the complexity of the commissioning: 1 or 2 circulating pumps, water filter

kit, safety valve, expansion vessel, flow switch. With all these
elements included inside the unit, it is just a matter of con-
necting the chiller to the system. In particular, a buffer tank
(whose capacity is 1000 litres for all the models) is available
in two different configurations: hydraulically and mechanic-
ally connected to the unit (whose length is now increased)
or shipped loose for those installations which require more
flexibility.
But, if some or all of these components are already present
in the hydraulic line, Liebert HPC - S 017- 032 can be
equipped only with what is not already connected in the sys-
tem. This level of flexibility allows true customization of the
unit.
Compactness: Small Footprint
The Liebert HPC - S 017 - 032 series achieves the high effi-
ciency performance and low sound emission previously de-
scribed with a compactness which is one the highest in its
category.
This result is possible thanks to the high quality components
selected and a design which takes into consideration the dif-
ferent aspects and needs of a chiller installation.
In this way the installation area can be optimized, leaving more space for other building elements. Com-
bining this aspect with the possibility of including all of the hydronic components inside the unit, Liebert
HPC- S 017 - 032 series is really a leader in terms of easy and compact installation
