What is a Cooling Distribution Unit (CDU)?
A cooling distribution unit is a specialized component in liquid cooling systems designed to manage and distribute coolant between IT equipment and the facility’s central chiller system. By isolating facility water from sensitive IT hardware, CDUs provide efficient, safe, and reliable cooling for mission-critical environments.
Key benefits include:
- Improved thermal efficiency for high-density computing environments
- Reduced power consumption compared to air cooling systems
- Enhanced scalability for growing data centers
- Protection of IT equipment from contaminants in facility water
- Lower operational costs and carbon footprint
