CDW CRAC Servicing

Indigi Power & Cooling provides servicing for CDW (Condenser Water) CRAC systems, supporting cooling infrastructure used in data centres, telecommunications facilities, mechanical switch rooms and electrical switch rooms.

These systems rely on condenser water loops connected to cooling towers to remove heat from precision cooling equipment. Regular servicing ensures stable cooling performance and reliable heat rejection for mission-critical environments.

Our engineers provide CRAC servicing across Brisbane, Sydney and Melbourne, helping organisations maintain reliable cooling infrastructure.

CDW CRAC Maintenance Services include

• condenser water loop inspections
• cooling coil cleaning
• condenser water valve and actuator checks
• airflow optimisation and balancing
• fan and motor inspections
• humidity and temperature calibration
• cooling system diagnostics and testing

• inspect air filters and airflow
• check condensate pumps
• verify system alarms and general operation

Quarterly (Professional Inspection)
• belt tension and fan motor inspection
• motor mount and vibration checks
• humidifier operation verification
• condenser water flow and pressure checks

Annually (Comprehensive Service)
• electrical connection inspection and infrared scan
• condenser coil cleaning
