Why Liquid Cooling?
For increased performance, energy efficiency, and cost savings, there is simply no substitute for direct-to-chip liquid cooling. No other system unlocks the full potential of your data center while simplifying installation and maintenance like Danfoss fluid conveyance solutions.
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 enable increased chip density, unlocking your data center's full potential. Danfoss' hoses and connectors route coolant from the source to the chip, keeping your high-performing processors running smoothly, even during peak loads. This means consistent computing power and increased performance when you need it most.
Up to 40% energy use reduction with water cooling
