Indigi Power and Cooling • Melbourne and Victoria

Melbourne carries one of Australia's largest concentrations of enterprise IT, government infrastructure, and colocation capacity, and every kilowatt of that load depends on uninterruptible power supplies and precision cooling staying reliable. Indigi runs a dedicated Melbourne hub so Victorian customers get local response for UPS servicing, battery replacement, and CRAC maintenance rather than waiting on a crew mobilised from another state.

Melbourne's climate brings its own challenge: sharp temperature swings and the summer heatwave events the city is known for. A run of 40-degree days puts real strain on condensers and compressors, and it is exactly when a neglected CRAC unit is most likely to fail. At the same time a UPS that drops its load, or a battery string that fails a load test during a grid event, defeats the entire purpose of the system. Indigi keeps power and cooling in spec with scheduled maintenance, fast callouts, and clear written reporting.

UPS maintenance and battery service in Melbourne

A UPS is only as reliable as its batteries. Valve-regulated lead-acid (VRLA) batteries last around 3 to 5 years, and less when a room runs hot during summer. Indigi's Melbourne 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 Melbourne installations are covered by our single-phase and three-phase UPS installation services.

CRAC and precision cooling service in Melbourne

Melbourne's heatwave events make reliable data centre cooling critical. Indigi services all three CRAC topologies: direct expansion (DX), chilled water (CHW), and condenser water (CDW). Larger enterprise and colocation facilities 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, so the room holds temperature even when the outside air is at its worst.

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 Melbourne 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 Melbourne

Planning a new server room or upgrading an existing one in Melbourne? 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 and topology. Plan the project with our team, then talk to us about server room cooling design and installation or CRAC installation and commissioning.

Coverage across Victoria and Australia

Industries we support across Melbourne

Critical power and cooling reach far beyond the data floor. Across Melbourne, Indigi maintains UPS and CRAC systems for hospitals and aged care, where continuity protects patient safety and cold-chain storage; for state and local government facilities bound by availability standards; for financial services and professional firms that cannot tolerate transaction downtime; and for manufacturing, logistics, and food processing operators whose control systems and refrigeration must stay under continuous protection. Universities and research institutions across the metropolitan area also rely on us to keep laboratory and compute infrastructure running.

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 Melbourne 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. These matter most in the days before a heatwave, when a system already running at its margin has no headroom left. Catching them on a planned visit costs a fraction of an unplanned outage, which is why a maintenance plan pays for itself.

Why Melbourne organisations choose Indigi

Indigi Power and Cooling is Indigenous and Veteran-owned, Supply Nation registered, and listed on ICN Gateway. For Melbourne's many government, defence, and enterprise buyers 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 Melbourne hub means Victorian customers get local accountability and response, not a ticket in an interstate queue.

Frequently asked questions

Do you service UPS and CRAC systems across regional Victoria?

Yes. Indigi's Melbourne hub covers the metropolitan area including the CBD, Docklands, Port Melbourne, Dandenong, and Tullamarine, and travels to Geelong, Ballarat, and other regional Victorian centres for scheduled work and projects.

How do Melbourne heatwaves affect data centre cooling?

Extended runs of 40-degree days push condensers and compressors to their design limits, which is exactly when a CRAC unit low on refrigerant or with fouled coils is most likely to fail. Regular maintenance before summer, including coil cleaning and refrigerant checks, is the best protection against a heat-driven cooling failure.

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. Mission-critical and data centre sites often move to twice-yearly servicing. Our annual plan schedules these visits automatically so nothing is missed.

How cool should a Melbourne 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 Melbourne's 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.
