Liebert PDX
15 – 165 kW

A DX precision cooling solution featuring Digital Scroll technology for efficient and reliable operation in small and medium-sized data centers.

Liebert PDX High-Efficiency
DX Cooling System

An intelligent and scalable cooling architecture designed to support stable data center operation around the clock.

Liebert® PDX is an advanced direct-expansion (DX) precision cooling system designed for small and medium-sized data centers. Copeland Digital Scroll™ technology adjusts cooling capacity according to changing IT loads.

Efficiency options such as Liebert EC Fan 2.0 and Liebert EconoPhase™ help reduce energy consumption, improve cooling performance and support lower PUE values.

EconoPhase™ Free Cooling Integration

Uses favorable outdoor conditions to extend free cooling operation, helping reduce PUE and operating costs.

Energy-Efficient Design

EC fans, modulating compressors, Digital Scroll technology and EconoPhase™ free cooling support efficient operation.

Flexible Cooling Configurations

Air-, water- and free cooling configurations support diverse data center environments and installation needs.

Intelligent and Scalable Control

Vertiv™ iCOM™ control adjusts cooling capacity to changing loads, supporting efficient operation in dynamic environments such as cloud data centers.

Ideal Applications
