Commissioned Properly. Handed Over Ready.

Commissioning is where a cooling installation proves itself

Background

At a site in New South Wales, our technician recently commissioned two 12kW rack-mounted CRAC units supporting an IT equipment environment. During testing, multiple alarms were identified on one unit.

Diagnosis and Resolution

Diagnostic work traced the remaining high-pressure alarm to an open control signal between the rack-mounted cooling unit and its external unit. Once the connection was restored, the alarm cleared and the unit operated normally. The second unit completed testing without issue.

Project Highlights

• Two 12kW rack-mounted CRAC units commissioned
• Network connection established for unit control
• Refrigerant and control-system checks completed
• Customer-requested temperature set to 21°C
• Both units completed mains-failure testing

Handed Over Ready

Identifying and correcting issues before handover is what ensures cooling equipment is operating as intended, and ready to support the environment around it.

Key Takeaways

✔ Two 12kW rack-mounted CRAC units fully commissioned
✔ Alarm traced to an open control signal and resolved on site
✔ Refrigerant, control-system and mains-failure testing completed
✔ Customer-requested set point of 21°C confirmed
✔ Both units tested and handed over ready to support the environment
