STULZ CyberRack Active Rear Door

STULZ has updated its CyberRack Active Rear Door. Building on the features of the previous model, the new CyberRack Active Rear Door is a space-saving, rear-mounted heat exchanger with electronically commutated (EC) fans that capture heat directly at the exact point of generation.

The new model can be deployed in both air- and liquid-cooled data centre environments. Integrated sensors continuously monitor both return and supply air temperatures within a server rack to provide optimal cooling performance. As a result, cooling output automatically adapts to server heat load, delivering consistent operation regardless of any workload fluctuations, STULZ says.

With a compact footprint, the model can be deployed without rack repositioning, making it suitable for retrofit projects and environments where floorspace is limited. Custom adaptor frames allow seamless integration with a wide range of rack sizes, supporting standalone operation, supplemental precision air conditioning or hybrid deployments alongside direct-to-chip liquid cooling.

Designed for easy maintenance, the product has a two-step door opening of more than 90°, providing access to fans and coils, while hot swappable axial fans with plug connectors help to simplify servicing and minimise downtime. Alongside low noise emissions, the system’s differential pressure control adjusts fan speed to match the server’s airflow requirements.

Featuring a 4.3-inch touchscreen with unified menu logic, the integrated STULZ E² intelligent control system enables advanced functions such as redundancy management, cross-unit parallel operation, standby mode with emergency operation, and smooth integration with building management systems.
