Data center cooling: enabling the next generation of digital infrastructure
Cooling already accounts for a significant share of a data center’s total energy consumption. As power densities rise, inefficiencies directly limit computing capacity and profitability, driving demand for highly efficient, reliable, and scalable cooling solutions.
With increasing processor power and rack densities, liquid cooling is becoming essential. Danfoss supports this shift with an end-to-end portfolio designed to ensure precise temperature control, system safety, and operational flexibility.
Liquid cooling: from the CDU to the chip
Danfoss provides a comprehensive portfolio of modular components and solutions that enable the design and optimization of liquid cooling systems — from the Coolant Distribution Unit (CDU) to the chip level. The portfolio ensures precise temperature control and efficient thermal management and includes pre-engineered valve trains designed to connect CDUs to server racks—simplifying installation, improving system integration, and supporting reliable, high-performance operation across the entire cooling loop.
Key products highlight for CDUs and racks include:
- XB67 brazed plate heat exchanger is optimized for high-efficiency liquid-to-liquid applications. The CDU-focused portfolio delivers approach temperatures of 2°C to 4°C, enabling CDU development up to 1.3 MW. This results in a highly efficient CDU solution with a low LMTD approach temperature
- Alsmart® is a programmable HVAC controller platform engineered with a strong focus on cyber-security. Combining intuitive programming, best-in-class hardware, and advanced remote monitoring capabilities, it enables intelligent, connected, and cyber-secure control of CDUs
Server racks
