Rear Door Heat Exchangers: cooling that scales with rack density

As rack densities rise, maintaining cooling efficiency becomes increasingly challenging. While fan wall architectures can improve airflow performance, the energy needed to move larger air volumes can increase quickly in high-density environments.

Cooling matched to IT demand

Rear Door Heat Exchangers scale cooling directly with rack heat output, helping align energy consumption more closely to the real demand created by IT equipment. By placing cooling at the rack level, this approach supports a more targeted thermal strategy for dense deployments.

A more localized cooling approach

Localizing cooling at each rack can also reduce the operational impact of individual maintenance events or failures. For teams planning direct-to-chip and other high-density data center environments, Rear Door Heat Exchangers offer a practical way to pair cooling capacity with the load it is designed to support.
