CRAC Unit Commissioning & Acceptance Testing | Australia
Manufacturer-aligned CRAC commissioning, performance testing and SAT documentation for new and refit installations.
Commissioning a CRAC unit verifies that the unit, its controls, and the wider mechanical infrastructure perform per design specification before the protected room goes live. It is a structured set of acceptance tests that captures pressure, temperature, airflow, valve actuation, and alarm response data for client handover.
CRAC Services provides manufacturer-aligned commissioning across all major brands. Our engineers are factory-trained on Vertiv Liebert, Schneider Uniflair, Stulz and Daikin Applied, and provide commissioning sign-off required to activate full warranty cover.
Site Acceptance Test (SAT) documentation is delivered in industry-standard format with all readings, control sequences captured, and pass/fail criteria — suitable for ISO audit trails, lender milestones, and client handover.

FAQs
Frequently asked questions
Why is manufacturer commissioning required?
Most CRAC manufacturers — Vertiv Liebert, Schneider Uniflair, Stulz — require their factory-trained engineers to perform initial commissioning to activate the full warranty. Self-commissioning typically reduces warranty cover. Manufacturer commissioning also ensures firmware, control logic, and refrigerant charge are configured per the validated reference build.
How long does CRAC commissioning take?
Single-unit DX commissioning is typically 4-6 hours including SAT documentation. Multi-unit CHW commissioning takes a day per cluster, including rotation testing and BMS integration. High-density / liquid cooling commissioning may extend to multiple days for full thermal mapping.
Do you provide BMS / DCIM integration?
Yes — we configure Modbus, BACnet/IP and SNMP integration with major BMS and DCIM platforms (Schneider StruxureWare, Vertiv Trellis, Honeywell EBI, Tridium Niagara). We provide point lists and tag mapping documentation as part of the SAT pack.
