Indigi Power and Cooling • Sydney and New South Wales

Sydney is Australia's largest data centre market. The corridor running through Macquarie Park, North Ryde, and out to Western Sydney concentrates more critical IT load than anywhere else in the country, and that load depends entirely on uninterruptible power supplies and precision cooling staying in spec around the clock. Indigi runs a dedicated Sydney hub so that NSW customers get local response for UPS servicing, battery replacement, and CRAC maintenance without waiting on an interstate crew.

Whether you operate a colocation facility, an enterprise server room, a hospital, or a financial trading floor, the failure modes are the same. A UPS that drops its load takes the site down. A battery string that fails a load test during a grid event defeats the entire purpose of the system. A CRAC unit that loses charge lets the room drift past the ASHRAE TC 9.9 recommended envelope of 18 to 27 degrees Celsius, and servers throttle or shut down. Indigi keeps power and cooling reliable with scheduled maintenance, fast callouts, and clear written reporting.

UPS maintenance and battery service in Sydney

A UPS is only as strong as its batteries. Valve-regulated lead-acid (VRLA) batteries last around 3 to 5 years, and less if the room runs hot. Indigi's Sydney UPS maintenance covers single-phase and three-phase systems from Eaton, APC, and Vertiv Liebert, and includes battery testing and replacement, capacitor and fan inspection, firmware verification, and a full load test backed by a written condition report.

Book a UPS maintenance visit or set up an ongoing UPS maintenance plan. New Sydney installations are covered by our single-phase and three-phase UPS installation services.

Data centre and CRAC cooling service in Sydney

Sydney's data centre density means precision cooling is not optional. Indigi services all three CRAC topologies: direct expansion (DX), chilled water (CHW), and condenser water (CDW). The larger colocation and enterprise facilities across Macquarie Park and Western Sydney typically run chilled water plant, while smaller comms and edge rooms use DX units. Maintenance covers refrigerant charge and leak checks, compressor and fan health, coil cleaning, humidifier service, filter changes, and control and alarm verification.

Explore DX CRAC servicing, chilled water CRAC maintenance, condenser water CRAC servicing, or the full CRAC unit maintenance program. Genuine Liebert CRAC spare parts are available for Sydney sites. Not sure which topology you have? Our team can identify it as part of a CRAC unit maintenance assessment.

Server room design and installation for Sydney

Fitting out a new server room or expanding an existing one in Sydney? Indigi designs and installs combined power and cooling systems sized to your real heat load. A small comms room fit-out typically runs $8,000 to $15,000, a mid-size server room $25,000 to $45,000, and a large room $45,000 to $60,000 or more depending on redundancy. Plan the project with our team, then talk to us about server room cooling design and installation or CRAC installation and commissioning.

Coverage across New South Wales and Australia

Industries we support across Sydney

Critical power and cooling reach well beyond the colocation halls. Across Sydney, Indigi maintains UPS and CRAC systems for financial services and trading operations where milliseconds of downtime carry real cost; for hospitals and aged care, where power continuity protects patient safety and cold-chain storage; for state and federal government facilities bound by availability and security standards; and for telecommunications, media, and cloud operators whose edge and core sites cannot go dark. Universities and research institutions across the metropolitan area also depend on us to keep laboratory and compute infrastructure protected.

We support UPS systems in specialised applications too: vaccine and pharmacy fridges that need cold-chain power protection, lift and elevator controllers governed by AS1735, and electrical switchrooms that need dedicated cooling. Whatever the load, the discipline is the same: test the batteries, verify the transfer, keep the room in spec, and document everything.

Common faults Indigi catches before they cause an outage

Most critical power failures are predictable and preventable. The faults we most often catch during scheduled Sydney maintenance include battery strings that have lost capacity and will not carry the load for their rated runtime, swollen or leaking VRLA cells caused by heat, ageing electrolytic capacitors nearing end of life, blocked or failing cooling fans inside the UPS itself, and firmware that is out of date. On the cooling side, the recurring culprits are low refrigerant charge from slow leaks, coils fouled with dust that reduce heat-exchange efficiency, clogged filters that choke airflow, humidifier faults, and alarm or control settings that have drifted out of range. Catching any one of these on a planned visit costs a fraction of an unplanned outage, which is exactly why a maintenance plan pays for itself.

Why Sydney organisations choose Indigi

Indigi Power and Cooling is Indigenous and Veteran-owned, Supply Nation registered, and listed on ICN Gateway. For the many government, defence, and enterprise buyers in Sydney with Indigenous procurement targets or Reconciliation Action Plans, engaging Indigi contributes directly to those commitments while delivering the same technical standard as any national maintenance provider. Our Sydney hub means NSW customers get local accountability and response, not a ticket in an interstate queue.

Frequently asked questions

Do you service the Macquarie Park and Western Sydney data centre corridor?

Yes. Indigi's Sydney hub covers the full data centre corridor through Macquarie Park, North Ryde, and Western Sydney, along with the CBD, Parramatta, Newcastle, Wollongong, and Canberra. We service both colocation halls and enterprise server rooms.

How often should a UPS be serviced?

Most critical UPS systems should be inspected at least once a year, with battery testing at every visit. High-density data centre and mission-critical sites often move to twice-yearly servicing. Our annual plan schedules these visits automatically so nothing is missed.

What is the difference between DX, chilled water and condenser water CRAC units?

Direct expansion (DX) units reject heat through a refrigerant circuit and are common in smaller rooms. Chilled water (CHW) units use a central chiller plant and suit larger facilities. Condenser water (CDW) units reject heat to a cooling tower loop. Indigi services all three and can help you identify which you have during a maintenance assessment.

How cool should a Sydney server room be?

ASHRAE TC 9.9 recommends keeping the cold aisle between 18 and 27 degrees Celsius with relative humidity managed to prevent condensation and static discharge. Reliable CRAC maintenance keeps the room inside that envelope even during summer heat events.

Are you able to support Indigenous procurement requirements?

Yes. Indigi is a Supply Nation registered, Indigenous and Veteran-owned business listed on ICN Gateway, so engaging us for critical power and cooling work counts toward Indigenous procurement targets and Reconciliation Action Plan commitments.
