Vertiv 177187G1L Cooling Duct | Thermal Heat Reject Duct

Keep heat moving out of the way with a Vertiv cooling duct designed for edge thermal management. In compact infrastructure environments, airflow direction matters. A properly matched heat-reject duct helps guide exhausted thermal energy away from sensitive equipment and supports more predictable cooling performance. This duct is intended for installations using the top ECM configuration, where managing rejected heat is part of maintaining stable operation. For teams running edge systems in closets, micro data centers, or other space-constrained rooms, purpose-built airflow accessories can make the difference between a tidy thermal path and recirculated hot air. At approximately 1.40 lb, it is a lightweight accessory that adds targeted thermal control without introducing unnecessary bulk. It is a practical fit for deployments where cooling efficiency, equipment spacing, and serviceability all matter. When the cost of thermal inefficiency is downtime or reduced hardware life, a dedicated heat-reject duct is a small component with outsized value.
