Freecooling Chillers

Liebert® HPC-L and Liebert® HPC-M Freecooling ChillersChillers with 700-1600 kW Cooling Capacity

The Liebert HPC freecooling chiller is the ultimate chilled water-based solution delivering high efficiency and reliability. Its freecooling and compressor functioning options make it ideal for data center applications with cooling needs ranging from 350 kW to above 20 MW. Three different sound emission versions offer the possibility to choose standard or unrivalled low noise levels.

The built-in freecooling section together with the "Supersaver" system, guarantee the complete integration with indoor air conditioning units and allow significant energy savings, while increasing the system’s lifetime and reliability.

The unit’s maximum efficiency is reached through the leveraging of its free cooling capability and the embedded iCOM® control function, which ensures the efficient management of system load sharing, further maximizing performance.




Integrated freecooling system to enhance energy savings and increase reliability.

Fast Start Ramp

Fast Start Ramp is the innovative technology which ensures immediate restoration of chiller operation following a power restart. This reliable technology allows the activation sequence to begin 20 seconds after power restoration, ensuring water temperatures remain stable.

iCOM® Control

The iCOM software has been developed by Emerson Network Power to specifically ensure the intelligent control of the units within the dynamic data center environment.

Screw Compressors

Excellent performance is ensured both at full and partial load as a result of the continuous capacity control system integrated within the control logic.

EC Fans

High efficiency EC motors guarantee a 25% saving in energy consumption compared to traditional AC motors. EC fans are further optimized for operation, eliminating electromagnetic-related noise and minimizing overall sound emission.


This unique functioning mode may be set up in combination with the Liebert® PCW in order to additionally enhance energy savings.  This function allows the floor mount units to communicate via LAN with the freecooling chiller, automatically increasing water temperature when the thermal load decreases. This in turn enhances the system’s seasonal efficiency and freecooling operating time.
