1.1General Product Information

1.1.1Product/System Description

Liebert’s XDP refrigerant distribution unit is an interface between the building chilled water system and the cooling modules in the Liebert XD system. It is designed to circulate and control refrigerant to the cooling modules that are in the room with heat-producing equipment. The Liebert XDP consists of a cabinet that includes a heat exchanger, circulating pump(s), control valve, receiver, controls, valves and piping.

The Liebert XDP monitors room conditions and prevents coil condensation by maintaining the refrig- erant being pumped to the cooling modules at a temperature above the room’s dew point.

All functions, such as switching pumps (if applicable), controlling refrigerant temperature, etc., are automatic.

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.

The Liebert XDP is rated for 160kW (546,000 BTU/H) of cooling.
