As data centres evolve to support AI and high-performance computing, cooling technology has become more crucial than ever.

Modern computing workloads generate significant heat, making efficient cooling systems essential for reliable operation and optimal performance.


The Growing Cooling Challenge

Today's computing demands push traditional cooling solutions to their limits. AI workloads, in particular, can generate substantial heat that must be managed effectively to prevent system throttling and maintain consistent performance. Without adequate cooling, these intensive operations risk hardware damage and system failures.


Advanced Cooling Technologies

Modern data centres employ various cooling technologies to manage heat output effectively. Direct Expansion (DX) CRAC systems offer precise temperature control, while In-Row cooling provides targeted cooling where it's needed most.

These technologies, when properly implemented, ensure optimal operating conditions for critical infrastructure.

Redundancy also plays a vital role in cooling system design. N+1 configurations ensure continuous operation even during maintenance or unexpected issues, providing the reliability that modern businesses demand.


The Lunar Digital Approach

At Lunar Digital, we've implemented cutting-edge cooling solutions across our facilities. Our Manchester data centres feature N+1 DX CRAC systems complemented by In-Row cooling, delivering precise temperature management with an annualised PUE of 1.3.

Each of our facilities is optimised for its environment and requirements. For example, our Norway facility utilises advanced adiabatic cooling technology, taking advantage of the local climate to deliver exceptional efficiency.


Reliable Infrastructure

Cooling is just one part of our comprehensive approach to infrastructure reliability. Our facilities feature N+1 generator redundancy with extended fuel capacity, ensuring continuous operation for critical workloads.

This robust infrastructure supports our cooling systems, creating a reliable environment for demanding applications.


Looking Forward

As computing requirements continue to grow, particularly in AI and high-performance computing, effective cooling becomes increasingly vital. Businesses need partners who understand these challenges and can provide solutions that scale with their needs.
