Slim and Flexible of Modularized Design
Available in three widths and three depths, air flow front / side discharge, and adjustable vent air baffle. Allows us to provide a customized fit for different data center configurations. Suitable for racks from any manufacturers, you can also easily expand or reconfigure your cooling infrastructure without disrupting the existing setup.

Ideal for High Density Application
The growing demand for expansive data storage and computing capacity confronts data centers with a critical challenge. Traditional cooling solutions struggle to cope with rasing heat densities. The RDx system, functioning as a rear-mounted radiator door on the rack, facilitates efficient heat exchange with cooling gas or water. This minimizes the risk of hot air recirculation within the rack, ensuring optimal operating conditions for data servers.
