DX cooling systems use a refrigerant gas and condenser units to chill the air. They are most effective in small scale server rooms and cheaper to install than chilled water.
Main reasons to choose a direct expansion cooling system:
- Comparatively cheap to install
- Minimal equipment and pipe work is compact
- Heat transfer is very effective
- Liquid is eliminated from the data centre as the refrigerant boils at -40C
However, DX cooling tends to have higher running costs than chilled water systems and is harder to scale up or down.
Additionally, as the chillers remove moisture from the air in your server room, we recommend installing a humidifier at the same time as your cooling system.
One solution can never fit all. RMD service consultants assess your requirements individually and discuss cooling system options that are suitable for your IT infrastructure facility.
