Vertiv Liebert DCD
Manage heat at the rack level with a rear-door heat exchanger architecture designed to support room-neutral conditions in the data hall.
Heat Removal at the Source
Targeted, Space-Efficient Rack Cooling with Liebert DCD
Thermal loads generated by high-density racks cannot always be managed efficiently through room-level cooling alone.
Liebert DCD captures heat at the rack exhaust, helping reduce hot spots and returning air to the data hall at near-room temperature. This room-neutral approach supports a more controlled thermal architecture in IT environments with high-density compute, AI and GPU workloads.
Up to 50 kW of Cooling per Rack
Designed for high-density applications from 5 to 50 kW, Liebert DCD supports different rack widths and capacity requirements through the DCD35, DCD47 and DCD50 models.
Space-Efficient Installation
Mounts directly to the rear of the rack, helping preserve floor space for additional critical IT equipment.
Low Energy Consumption
Passive models require no fans, while active configurations use high-efficiency EC fans to help reduce operating costs.
Intelligent Monitoring and Scalability
Supports 0–100% capacity modulation and optional monitoring and control features for a more flexible response to changing heat loads.
Ideal Applications
High-Density and Expandable IT Environments
Liebert DCD is well suited to applications where rack-level heat density is increasing and room-level cooling alone is no longer sufficient. It is particularly relevant for high-density compute environments, colocation facilities, capacity-expansion projects in existing data centers and installations where space efficiency is critical.
Its rear-door design makes it easier to add targeted cooling without completely redesigning the existing data hall.
Recommended Applications
Why Choose Liebert DCD?
Controlled, Room-Neutral Cooling for Critical IT
Liebert DCD manages heat at the rack level, helping reduce hot spots and maintain a more balanced thermal environment across the data hall. Instead of increasing cooling across the entire room, it enables a more targeted cooling strategy at the point of demand.
System Compatibility and Operational Flexibility
Its scalable, modular architecture allows additional rack-level cooling capacity to be deployed as IT loads grow.
Technical Highlights
Heat Removal at the Source
Captures heat at the rack exhaust, helping reduce the thermal load released into the data hall.
Passive or Active Configuration
Available as a passive rear door or an active module with EC fans for different rack-density requirements.
No Additional Rack Footprint
Integrates with the rear of the rack without consuming valuable additional white space.
Flexible Installation
Connection options support deployment in facilities with or without raised floors.
Monitoring and Control Options
An optional monitoring and display package can include door switches, temperature sensors and leak detection.
Long-Term Operation
A low-maintenance design with fewer moving components supports operational continuity.
Related Solutions
Liebert DCD delivers greater value when considered as part of an integrated high-density cooling architecture that includes racks, cooling distribution units, power distribution and monitoring. When combined with CDU-based liquid distribution systems, it can support more controlled water-temperature management and broader system integration.
