The rapid growth of AI and high-performance computing is accelerating the shift toward liquid cooling in data centers. As rack densities increase and thermal loads intensify, traditional air cooling is reaching its limits.
To support this transformation, Danfoss is strengthening its focus on enabling the development of high-performance liquid cooling systems, particularly around Coolant Distribution Units (CDUs), a critical element in modern cooling architectures.
“AI-driven data centers are pushing cooling technologies to new limits. What we see from our customers is a clear need for higher performance, better integration and faster scalability. With our modular solutions, broad portfolio and application expertise, we support the development of next-generation liquid cooling systems, helping our partners design and deploy high-performing CDUs with confidence.”

As both a technology provider and application expert, Danfoss supports OEMs and system integrators with modular solutions, integrated technologies and system-level expertise, helping customers design more efficient, reliable and scalable cooling architectures.
At the center of liquid cooling systems, CDUs play a key role in managing performance, efficiency and footprint. Optimizing these systems requires more than individual components. It requires technologies that work seamlessly together.
Danfoss addresses this with a broad portfolio across the CDU ecosystem, combining components into modular solutions supported by simulation tools and testing capabilities.
This approach enables customers to:
• Improve thermal performance
• Reduce system complexity
• Optimize footprint
• Accelerate development and deployment
In addition, Danfoss’ global manufacturing footprint and robust supply chain across Europe, North America and Asia enable customers to scale rapidly and deploy solutions reliably worldwide—a critical factor in the fast-growing data center market.
