Vertiv CPQ-893983-02 Passive Rear Doors | In-Row Cooling

Shape rack airflow with passive rear doors built for Vertiv DCD35A801 environments. This 22-door set is intended for in-row cooling deployments where thermal control depends on enclosure design and system-level airflow planning rather than fan-assisted rear extraction. Passive rear doors are a strong fit when you want a simpler thermal path and prefer to keep cooling behavior tied to the surrounding infrastructure. They help support rear-side ventilation while avoiding the added complexity of powered components, which can be useful in deployments that prioritize predictable airflow architecture and straightforward maintenance planning. With a quantity of 22, this configuration is well suited to multi-rack rollout across a row or zone. It can help maintain consistency in environments where the cooling strategy is already balanced and the goal is to preserve airflow discipline at the rack boundary. Choose this option when your infrastructure design calls for rear-door ventilation support without active fan hardware, and when you want a clean fit for enterprise row-based cooling plans.
