CRAC for Data Centres & IT Infrastructure | Australia
Data centres are the canonical CRAC use case. Cooling architecture decisions — perimeter vs in-row, hot-aisle containment, set-point envelope — directly drive PUE and capital cost.
CRAC Services designs, services, and decommissions precision cooling for Australian data centres of all scales — from edge facilities to hyperscale builds. Our work covers all topologies (DX, CDW, CHW), all major brands (Vertiv Liebert, Schneider Uniflair, Stulz), and all density profiles from traditional 5kW/rack through to 100kW liquid-cooled AI pods.

Considerations
Key considerations for Data Centres & IT Infrastructure
01
Set-point envelope
Operating in the warmer end of ASHRAE TC 9.9 recommended (24-27°C supply) reduces cooling energy substantially without reliability impact for most modern IT.
02
High-density bridging
When rack densities exceed ~10kW, perimeter cooling becomes inefficient. In-row cooling, RDHx, or liquid cooling becomes economic.
03
Concurrently maintainable
Tier III+ data centres need cooling capacity that can withstand the loss of any single CRAC unit without thermal alarm.
