Why Liquid Cooling?

Increased performance, energy efficiency and cost savings. Direct-to-chip liquid cooling unlocks the full potential of your data center while simplifying installation and maintenance.

Energy sustained

Danfoss’ direct-to-chip liquid cooling improves data center Power Usage Effectiveness (PUE) by efficiently and cost-effectively removing heat emitted by a server processor.

Performance unleashed

The thermal efficiency and reduced space requirements of liquid cooling enables increased chip density, while keeping your high-performing processors cool and running smoothly, even during peak loads. That means consistent computing power and increased performance when you need it most.

Source Line Solutions

Making connections you can count on

From main supply lines to single point connections, Danfoss provides the hardware to make your software work. Our range of fluid conveyance solutions enable you to engineer the safest and most efficient thermal management system for your cutting-edge data center.
