Featu res an d Benefi ts
Reliability and Low Environmental Impact
Reliability
The L i e b e r t H P C --- S 0 0 6 --- 0 2 2 series is equipped with two hermetic scroll com-
pressors, which represent state---of---the---art technology in this sector. They
have been designed and optimized for air---cooledwater chillerswithin air condi-
tioning applications.
The high volumetric efficiency ensures excellent performances of the Liebert
H P C --- S 0 0 6 --- 0 2 2 units at full load operation and especially at partial load.
Extremely low noise operation and the absence of vibrations aid the installation
of the unit in city sites requiring strict noise limits.
The wide operati ng range, bearing lubrication, component oversizing, absence
of vibrations and few moving parts, together with the resistance to liquid slug-
ging and compressor electronic control integrated with the machine micropro-
cessor enhance the well---known characterist i cs of operat ing reliabilit y and long
life typical of this compressors type.
AllL i e b e r t H P C --- S 0 0 6 --- 0 2 2 units are run tested at the factory beforeshipment.
High outdoor temperature
The oversizing of heat exchangers and the wide operating range of the scroll compressors permit the
use of L i e b e r t H P C --- S 0 0 6 --- 0 2 2 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 toler ate/withstand amounts of liquid refrigerant that
would severely damage reciprocating compressor valves, piston rods and cylinders.
Low Sound Emission
The L i e b e r t H P C --- S 0 0 6 --- 0 2 2 series is characterized by unrivalled low sound emissions.
Compressors supported on anti---vibration mounts and positioned in a closed compartment, common
to all versions; fans specifically designed to reduce the sound emissions, a special compressor jacket
on the “B” version “models from C/FB0 011” (Digit 11 = B or D) and “G” version with 900 mm fans, and
also a special compressor’s box insulated on the “G” version with 800 mm fans “models from C/FG0 011”
allow the achievement of such performance.
All the models are equipped with stepless fan speed control, 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 measured at the same conditions with traditional fans.
