System Description

1.8Liebert XDP—Pumping Unit

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.

1.8.1Liebert XDP Minimum Load

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.
