Introducing the new rack cooling solution for new and existing HP 10K and 10K G2 Racks to improve datacenter airflow and eliminate datacenter hot spots. The 10000 G2 Rack Air Duct Kit channels the hot exhaust air from the rear of the rack directly into the top plenum (air return) to eliminate hot spots and air mixing in the datacenter as well as increase cooling efficiency by returning hotter air to the CRAH units. - Ideal for racks using 5-14 kW. Air duct with adjustable height for different air return heights. No fans or moving parts, use pressure from CRAE unit to extract air from rack.
