Rear Door Heat Exchanger (RDHx) – High-Density Data Center Cooling
The rear door heat exchanger is a highly efficient data center cooling solution designed to manage heat directly at the rack level across Dubai, UAE, and the Middle East. It enables targeted cooling for high-density IT environments without increasing room-level cooling demand.
This RDHx solution, also known as an active rear door heat exchanger or cooldoor, removes heat from server exhaust air before it enters the data center space. The door heat exchanger supports improved thermal efficiency and optimized airflow management.
Suitable for modern and scalable data center designs, RDHx cooling helps reduce energy consumption while maintaining stable operating temperatures in demanding Middle East climate conditions.
