Data Center Cooling Solutions

Liebert CRV
In-Row Cooling

Targeted cooling delivered close to the heat source for maximum efficiency.

Focus Cooling on the Rack,
Not the Room

An intelligent, scalable in-row cooling architecture designed to remove heat directly at the source in high-density rack environments.

Liebert® CRV integrates directly into the server rack row, positioning cooling close to the equipment generating the heat. It draws hot air from the aisle and directs conditioned air back toward the servers, improving cooling efficiency and supporting operational continuity. This approach is particularly effective in high-density data center environments.

Targeted Hotspot Control

Rack-level cooling helps eliminate localized temperature increases and hotspots that traditional room-based systems may not adequately address.

Optimized Efficiency

Variable-speed EC fans and digitally modulated compressors adjust cooling output to actual demand, helping minimize unnecessary energy consumption.

Maximum Flexibility

Available in 300 mm and 600 mm widths, with DX and chilled-water configurations, Liebert CRV adapts to a wide range of rack layouts and cooling requirements.

Intelligent Management

Integrated Vertiv™ iCOM™ control continuously monitors rack loads through up to 10 temperature sensors and adjusts system performance in real time.

Ideal Applications

High Heat Loads in Limited Spaces

Liebert CRV is well suited to rooms without raised floors and high-density zones added to existing data center environments.

Recommended Applications

Small and medium-sized data centers
High-density rack rows
Rooms without raised floors
Network and telecommunications rooms
Vertiv SmartAisle containment applications
