       Incorporates the whole experience of Emerson Network Power in a unique range of cabinet air coolers suitably designed to ensure performance and reliability.

       Liebert HPM units are cabinet air conditioners. These can feature EC fans, with several air delivery versions: downwards (underfloor delivery), upwards and “displacement”.

Liebert HPM

       Liebert HPM units are equipped with iCOM control, featuring an integrated Web connection and two optional graphic display types. Liebert HPM combines different cooling systems for the ideal solution to every facility:

Direct Expansion: available with the air- or water-cooled Copeland Digital Scroll compressors.

Chilled Water: to be used with Liebert HPC.

Dual-Fluid: matches low running costs and total reliability. It standard operates with chilled water, thus guaranteeing “business-continuity,” thanks to the spare compressors that can intervene in a few seconds, as soon as the central unit stops.

Free Cooling: no power consumption if needless. Working 365 days a year, it uses the low winter temperature to cool the rooms, without using compressors.

Features:

iCom Control

Several graphic display options

On-line unit log

Integrated Web communication

Preventive maintenance through an advanced troubleshooting

400 stored events/unit

Up to 16 stored temperature and humidity days

EC fans

AC powered 50/60 Hz without frequency converter

Static pressure continuous adjustment

Energy consumption lower by approx. 30% vs. AC motors

No maintenance

Long life transmission

Copeland Digital Scroll

Better room control

Energy saving with partial load

Quick adjustment to load changes

Simple and reliable mechanics

AC powered 50/60 Hz without frequency converter

EMC-free

Heat Exchange Surface

High Energy Efficiency Ratio (EER). It basically depends on the heat exchange surface. Refrigerating circuits consume less energy.

High Sensible Heat ratio (SHR). Sensible heat vs. latent heat. Technological applications require a high sensible heat discharge, without lowering the room humidity too much, as it would need to be restored through a humidifier.

 

Benefits:

Design

All components have been sized for the lowest possible stress. Models have been rigorously tested before being launched on the market. The Liebert HPM range is Eurovent certified.

Efficiency 

Over-sized heat exchangers and optimized aerodynamics allow one of the lowest energy consumption in the Precision Conditioning Cooling field.

Maintenance

The handy user interface and the quick front access to mechanical adjustments shorten the routine maintenance time.

Compactness

The compact design still ensures the best performance thanks to fluid-dynamic analyses and several lab tests.
