Emerson Xtreme Density Manuel D’Utilisation

The Liebert XDP isolates the building’s chilled water circuit from the pumped refrigerant circuit. The 

Liebert XDP circulates refrigerant to Liebert XDCF, Liebert XDH, Liebert XDO or Liebert XDV mod-

ules while preventing condensation by maintaining the refrigerant’s temperature above the dew 

point. The Liebert XDP employs two sets (for redundancy) of remote sensors to determine the temper-

ature and humidity in the air and instantly adjusts refrigerant supply temperature to compensate for 

changing conditions.

The Liebert XDP’s minimum recommended operating load is 20% of system nominal capacity. For 

example, a Liebert XDP160 60Hz system’s minimum load would be 32 kW. Loading below this value 

can unfavorably affect system operation. Consult factory for any loading below this recommendation.
