SmartRack SRTHERMDUCTMD Medium Height Thermal Duct Kit for 46in Deep Rack Enclosures
The SmartRack thermal duct kit is engineered for data centers and server rooms that need efficient passive cooling without additional power consumption. This medium height thermal duct system fits standard 42U and 48U rack enclosures measuring 46 inches deep, creating a sealed chimney that directs hot air directly into your facility's return air duct or ventilation system. By venting heat upward instead of recirculating it, this rack enclosure cooling solution helps your equipment maintain optimal operating temperatures, extends hardware lifespan, and significantly reduces energy costs. The three-piece adjustable design accommodates varying ceiling heights and ductwork configurations, making it ideal for retrofit installations and new deployments alike.

Frequently Asked Questions
How does a thermal duct kit improve rack cooling efficiency?
A thermal duct kit creates a sealed pathway that captures hot air rising from equipment and directs it into your facility's return air duct or ventilation system. This prevents hot air recirculation, maintains cooler inlet temperatures, reduces the workload on your HVAC system, and lowers overall energy consumption.
What is the difference between medium height and other thermal duct options?
The medium height thermal duct (17-28 inches adjustable) accommodates most standard ceiling heights and ductwork configurations. It provides optimal balance between thermal performance and installation flexibility for typical data center and server room environments.
Can this thermal duct kit fit my existing 46 inch deep rack enclosure?
Yes. The SmartRack SRTHERMDUCTMD is specifically designed for standard-width 42U and 48U rack enclosures 46 inches deep. The adjustable three-piece design accommodates various ceiling heights and ductwork layouts, making it suitable for both new installations and retrofits.
What cooling benefits will I see with passive heat venting?
Passive rack enclosure cooling eliminates hot air recirculation, reducing inlet air temperatures by 5-15°F depending on your facility layout. This allows equipment to run cooler, extends component lifespan, improves performance, and can reduce cooling energy costs by 10-20% or more.
