FAQ | Neurair Europe

1. Are CDUs compatible with existing cooling infrastructure?

Yes, CDUs are modular and scalable, making them easy to integrate into new or existing data center setups.

2. What is a CDU and why is it important?

A Coolant Distribution Unit (CDU) regulates and distributes liquid coolant to remove heat from high-performance IT equipment, ensuring efficient cooling in data centers.

3. What is the difference between Liquid-to-Liquid and Liquid-to-Air CDUs?

Liquid-to-Liquid CDUs transfer heat to a facility’s chilled water supply, while Liquid-to-Air CDUs expel heat into ambient air.

4. Can CDUs prevent condensation?

Yes, CDUs maintain coolant temperature above the dew point, preventing condensation inside the data center.

5. How energy-efficient are CDUs compared to air cooling?

CDUs provide higher energy efficiency and lower Power Usage Effectiveness (PUE) by using liquid cooling instead of traditional air cooling.

1. What is an RDHx and how does it work?

An RDHx replaces the back door of a server rack with a liquid-cooled heat exchanger to remove heat directly at the source.

2. Do RDHx systems require major data center modifications?

No, RDHx can be retrofitted into existing racks with minimal adjustments.

3. How much cooling capacity does an RDHx provide?

Depending on the model, RDHx units can handle up to 52.5 kW per rack.

4. Is RDHx better than traditional air cooling?

Yes, RDHx removes heat more efficiently, reducing reliance on air conditioning.

5. What type of coolant is used in RDHx?

Typically, water or a water-glycol mix is used for optimal thermal performance.

1. What is immersion cooling?

Immersion cooling submerges IT hardware in dielectric liquid, efficiently dissipating heat without the need for air cooling.

2. Is immersion cooling safe for IT hardware?

Yes, the dielectric fluid is non-conductive, ensuring safe operation while eliminating overheating risks.

3. What are the benefits of immersion cooling?

It reduces power consumption, eliminates fans, lowers noise, and improves thermal efficiency.

4. Does immersion cooling require specialized infrastructure?

Yes, immersion cooling systems need custom tanks and pumps but offer long-term energy savings.

5. Can immersion cooling be used for AI and HPC?

Absolutely! It’s ideal for high-density computing, including AI, HPC, and blockchain applications.
