CRAC Maintenance & Quarterly Servicing | Australia

Preventative CRAC maintenance, quarterly service plans and emergency fault response across all major precision cooling brands.

CRAC maintenance keeps computer room air conditioning and critical room cooling systems stable before faults become outages. A maintenance plan checks filters, coils, fans, refrigerant, condensate, humidifiers, alarms and controls on a recurring schedule matched to the room load and risk profile.

CRAC Services maintains DX, condenser water, chilled water, in-row and rear-door cooling systems across Australia. Our technicians support Vertiv Liebert, Schneider Uniflair, Stulz, Daikin Applied, Mitsubishi Heavy and Climaveneta equipment, including mixed fleets with legacy and current-generation units.

Each visit includes a written service report with readings, defects, photos, recommended parts and priority actions. Emergency fault response is available for sites with thermal alarms, compressor faults, water leaks, high supply air temperature or BMS alerts.

FAQs

Frequently asked questions

How often should CRAC maintenance be done?

Quarterly CRAC maintenance is the normal baseline for data centres and server rooms. High-density rooms, dusty environments and sites with older equipment may need monthly filter checks. Annual major service should include coil cleaning, electrical checks, refrigerant leak testing, control review and a written defect plan.

What is included in a CRAC maintenance visit?

A maintenance visit checks filters, coils, fans, compressors, refrigerant readings, condensate drains, humidifiers, controls, alarm history, BMS points and room temperatures. CHW and CDW units also need valve, actuator and water loop checks. The final report records readings, defects, photos and recommended priority actions.

Do you service all CRAC brands?

Yes. CRAC Services maintains Vertiv Liebert, Schneider Uniflair, Stulz, Daikin Applied, Mitsubishi Heavy, Climaveneta and legacy Emerson equipment. Mixed fleets are common, so our maintenance reports group issues by unit, brand, topology and priority.

Can you attend emergency CRAC faults?

Yes. Emergency response covers high temperature alarms, compressor faults, water leaks, blocked condensate drains, fan failures, refrigerant faults and BMS alarm escalation. For contracted maintenance clients, we already hold asset data and service history, which helps fault diagnosis move faster.
