CRAC Commissioning & SAT Packs
ARC-licensed CRAC commissioning, precision cooling commissioning, Site Acceptance Test packs and warranty activation support for new and refit installations.
Commissioning a CRAC unit verifies that the unit, controls, refrigerant circuit, airflow path and connected mechanical plant perform to the design brief before the protected room goes live. The process records pressure, temperature, airflow, valve actuation, alarm response and BMS point data for client handover.
CRAC Services provides manufacturer-aligned CRAC commissioning and precision cooling commissioning across Australia for Vertiv Liebert, Schneider Uniflair, Stulz, Daikin Applied and other precision cooling systems. ARC-licensed technicians complete refrigerant checks, start-up testing, setpoint tuning and fault simulation so the unit can enter service with clear evidence.
Site Acceptance Test documentation is delivered with readings, control sequences, alarm results, BMS point checks and pass/fail criteria. These SAT packs support warranty activation, ISO audit files, lender milestones, practical completion and facilities handover.
Commissioning also creates the baseline for future CRAC servicing. The SAT pack records the normal readings, alarm settings, sensor calibration and controls configuration that later maintenance teams use to detect drift before it affects the room.

FAQs
Frequently asked questions
Why is manufacturer commissioning required?
Most CRAC manufacturers require approved commissioning before the full warranty starts. Vertiv Liebert, Schneider Uniflair and Stulz units need start-up checks, control setup, refrigerant readings, airflow readings and alarm tests recorded by trained technicians. Self-commissioning can reduce warranty cover or leave no evidence for later claims.
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.
What is included in CRAC SAT documentation?
A CRAC SAT pack includes the unit model and serial numbers, refrigerant readings, supply and return air temperatures, airflow checks, control sequence results, alarm tests, BMS points, photos, pass/fail notes and outstanding defects. The pack gives facilities teams a clear baseline for future maintenance and warranty claims.
