CRAC Unit Servicing & Maintenance
Precision cooling kept precise, with a permanent servicing record that protects uptime and the asset history.
Computer room air conditioning (CRAC) units hold the tight temperature and humidity envelope that IT and critical equipment depend on. A drift or failure can mean thermal shutdown in minutes. Veritas MEP delivers planned CRAC servicing that keeps precision cooling within tolerance, and records every visit so the maintenance history is permanent and verifiable.
CRAC servicing covers refrigeration circuit and compressor performance, condenser and evaporator condition, fans and filters, humidification and dehumidification, controls and setpoints, leak detection, condensate management, and airflow. Performance is checked against the design envelope, not just for on/off operation, because precision cooling fails by drifting out of tolerance before it fails outright.
Each service creates a structured record against the asset: checks performed, readings taken, parts replaced, faults raised, and the compliance result, with a service certificate and an entry in the asset maintenance register. Refrigerant handling is conducted by appropriately licensed technicians and logged. The record stays with the asset on the Veritas Ledger through any contractor change.
Veritas MEP services CRAC and precision-cooling units across data centres, server rooms, control rooms, and critical facilities Australia-wide, with planned-preventive schedules and reactive support.
Deliverables
What's Included
Methodology
Our Process
Asset Onboarding
CRAC units are registered against the building with make, model, capacity, refrigerant type, and the room cooling-envelope targets, establishing the baseline record.
Planned Service Visit
Technicians service the refrigeration circuit, condenser, evaporator, fans, filters, humidity control, and controls, and verify performance against the design cooling envelope.
Refrigerant and Leak Management
Leak detection is performed and any refrigerant work is carried out by licensed technicians and logged, consistent with Australian refrigerant-handling requirements.
Certificate and Register Update
A service certificate is issued and the asset maintenance register is updated with checks, readings, parts, faults, and the compliance result.
Anchoring and Continuity
The record and certificate are anchored to the Veritas Ledger, keeping the full servicing history with the asset across contractor changes.

FAQ
Frequently Asked Questions
How often should CRAC units be serviced?
Precision-cooling units in critical environments are typically serviced quarterly, with filters and basic checks sometimes more frequent, because they run continuously and a drift in performance directly threatens IT equipment. The exact frequency depends on the unit, the heat load, the environment, and the criticality of the space. Continuous duty and tight tolerances mean CRAC units generally need more frequent attention than comfort air conditioning.
Why check performance against the design envelope rather than just operation?
Precision cooling rarely fails by simply stopping. It fails by drifting: temperature or humidity slowly moving out of the tolerance the equipment needs, or capacity quietly reducing as a circuit underperforms. Checking only on/off operation misses this. By measuring performance against the design envelope at each visit and recording it, drift becomes visible early, before it causes a thermal event, and the trend is preserved on the asset record.
Do you handle refrigerant legally and safely?
Yes. Refrigerant handling is carried out by appropriately licensed technicians in line with Australian refrigerant-handling and ozone-protection requirements, and refrigerant work is logged. This keeps the facility compliant and the records defensible. The refrigerant logs form part of the asset maintenance record anchored to the Veritas Ledger.
How does this protect data centre uptime?
Cooling is one of the most common causes of unplanned data centre downtime. Planned CRAC servicing keeps units within tolerance, catches degradation early, and ensures redundancy actually works when called upon. The permanent, trended record also supports better decisions about replacement and capacity. Because the history stays with the asset on the Veritas Ledger, uptime planning is based on the full maintenance picture, not whatever the current contractor happens to hold.
