Liebert® PEX

Liebert PEXEfficiency and Reliability In A Compact Package

The Liebert PEX is the Next Generation Precision Environmental Control System from Emerson Network Power. It is a result of extensive research and development, conducted with leading environmental control experts, consultants and major corporations. A wide range of standard units offered from 20 KW to 100 KW in Upflow & Downflow Configurations.

Key Features Contributing To the Superior Efficiency Of The Liebert PEX

  1. EC Fan
    The EC fan technology regulates airflow and reduces the fan input power. In-floor configuration further reduces energy consumption in downflow units. This significantly reduces energy consumption and provides longer component life. Managed through Liebert iCOM controls, EC fans deliver airflow for the optimal operating conditions for IT equipment.
  2. Digital Scrolll Compressor
    Liebert PEX with Digital Scroll Technology is highly reliable and is designed to achieve efficiency with flexibility and to lower TCO. The use of digital scroll technology actively manages capacity modulation from 20 percent to 100 percent. During the loaded state, cooling units consume full load power. On the other hand, during the unloaded state, the units run freely, consuming only about 10 percent of the full load.
  3. iCON Controller
    The teamwork mode in the iCOM Controller, a key feature of the Liebert PEX, ensures efficiency by allowing multiple units to work together as a single system to optimize room performance.
  4. Infrared Humidifier
    The Infrared Humidifier has been a feature on Liebert environmental control systems for over 45 years. Its rapid response and the ability to handle varying water conditions has made it an industry standard in applications that demand precise, particle-free humidity control.
  5. Dual Cool Option
    This option a provides a second coil that utilises the central building Chiller system water supply. The unit can function either as a DX (compressorized) or a Chilled water system. During times when the chiller supply is available compressorized operation is eliminated, reducing energy costs. In addition this option can provide increased redundancy and flexibility to the environmental control system.
  6. Free Cool Option
    Optional GLYCOOL free-cooling system permits compressorless operation in colder ambient conditions.
