FAQs
What is colocation data centre cooling?
Cooling designed for multi-tenant colocation and cloud facilities. Precision, high-density and liquid cooling systems keep customer racks within agreed temperature and humidity limits around the clock.
How do colocation providers cool high-density AI and GPU racks?
With close-coupled cooling such as in-row and rear-door units, or liquid cooling such as direct-to-chip and immersion, which remove heat at the rack rather than the room.
What is liquid cooling in a data centre?
Liquid cooling uses water or dielectric fluid to remove heat directly from servers. It handles far higher rack densities than air cooling and can reduce energy use.
What is the difference between direct-to-chip and immersion cooling?
Direct-to-chip cooling pipes liquid to cold plates on processors. Immersion cooling submerges entire servers in dielectric fluid. Both suit high-density AI and HPC workloads.
How can data centre cooling lower PUE?
Free cooling, adiabatic cooling and efficient liquid cooling reduce compressor run time, cutting the energy used for cooling and lowering a facility's power usage effectiveness (PUE).
Can data centre cooling scale as a colocation facility grows?
Yes. Modular cooling systems can be added in stages as customer demand and rack densities grow, avoiding oversized upfront investment and stranded capacity.
Is local support available for data centre cooling in Australia and New Zealand?
Yes. Local STULZ Oceania teams provide maintenance, spare parts and 24/7 support, backed by a global network of over 150 partners.
