Cyberair Cw and Dx
Indoor Precision Cooling
For More Information:
The benchmark of flexibility and energy efficiency
CyberAir CW and DX perimeter-mounted indoor precision cooling solutions control the conditions in the data center with the utmost precision, reliability, and energy efficiency. With 20–1,080 kW of cooling capacity, there is an air conditioner (CRAC) or air handler (CRAH) for almost any mission-critical application.
