Active Aisle Containment
Suitable for hot or cold aisle designs, this solution integrates our heat exchanger technology into the containment structure to minimize the mixing of hot and cold air.

Aisle containment, powered by active cooling fans
Whether you’re retrofitting or designing a new build, this solution delivers rack-level cooling without the complexity of full-room HVAC upgrades.
Our AHX units – the same active rear door heat exchangers used in our rear doors – are seamlessly integrated into an overhead cooling plenum above the aisle containment. These units dynamically adjust based on real-time heat loads, extracting heat directly at the source and discharging room-neutral air. This preserves aisle separation and eliminates thermal hotspots without impacting airflow balance.
By combining a widely adopted aisle containment design with upgraded active cooling technology, this solution is purpose-built for the evolving demands of AI and high-density workloads—while maintaining the speed, simplicity, and compatibility benefits that containment systems are known for.
