DX CRAC Servicing

Indigi Power & Cooling provides servicing for DX (Direct Expansion) CRAC systems, maintaining precision cooling infrastructure used in data centres, telecommunications environments, mechanical switch rooms and electrical switch rooms.

DX CRAC units use refrigerant-based cooling to remove heat from server rooms and critical infrastructure environments.

Regular maintenance ensures compressors, refrigerant circuits and airflow systems operate efficiently.

FAQs

What is a DX CRAC unit?
A DX CRAC system uses refrigerant to directly cool air within server rooms and telecommunications facilities.

How often should DX CRAC systems be serviced?
Most systems require preventative maintenance every 6–12 months depending on operating conditions but this is comes down to the bushiness criticality risk
