Liebert DS Direct Expansion Cooling System

The Vertiv DSE™ cooling platform is engineered for operators who need to drive down energy consumption, stabilize thermal performance, and protect IT loads without introducing operational complexity. This fully integrated, compressor-based economization system eliminates the maintenance burden of water-based solutions while delivering market-leading PUE performance for edge, enterprise, and hyperscale environments.

Key Value Drivers

• Compressor-based economization without water, pumps, or towers

• Up to 50% energy savings vs. traditional CRAC/CRAH architectures

• Predictable annualized performance in all climates

• Factory-assembled, plug-and-deploy configuration

• Rapid deployment timeline for greenfield and retrofit projects

• Full integration with Vertiv™ Liebert® iCOM controls

Product Overview

Vertiv DSE™ (Direct Expansion System with Economization) combines advanced DX cooling with integrated free-cooling technology. The system leverages a pumped refrigerant economizer, allowing heat rejection without mechanical cooling during favorable outdoor conditions. This design provides cooling stability comparable to chilled water—without any of the associated water, piping, or maintenance exposure.
