System Description

1.7 Liebert 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 of remote sensors to determine the temperature and humid-

ity in the air and instantly adjusts refrigerant supply temperature to compensate for changing condi-

tions.

1.7.1 Liebert 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.
