Rack Cooling Units and their benefits

Rack Cooling Units and their benefits

HDC+ 3.0 Rack: Closed configuration, in which the re-circulation of air is independent from the room. The airflow path is done through the front and rear part of the rack due to a metallic frame attached to the rack.

This additional structure allows using the total depth of the rack to install deeper servers and to organize cabling properly inside the rack. It is worth to mention that, performing the recirculation through the additional frame attached to the rack (front / rear) avoids pressure and cooling capacity losses due to obstructions in the air passage.

It is recommended for high density (>20Kw/rack) facilities and for isolated or specific control and/or restricted access installations.

With the rack cooling format, a closed loop is created by laterally connecting the rack to the cool unit by means of additional frames placed at the ends of the assembly enabling maximum use of the rack in depth and optimisation of the air flows.

When recirculating the air outside the rack, there are no obstructions or equipment to prevent the installed servers from being cooled properly, thus ensuring that the cool air reaches the front of the rack at all times, regardless of the position in which the servers are set up.

Furthermore, since the air is not expelled outside the aisle but rather moves through the front/rear frames, greater ΔT are achieved which ensures that the units continue to work in best cooling zone. The HDC-Rack is the most efficient solution, as it is possible to work with ΔT of the air up to 25°C, and is therefore the most ideal solution for ultra high-density applications combined with external Free-Cooling type chillers.

In addition, given that it is a thermally isolated format, with a protection grade of IP 40, it is ideal for installation in industrial and office environments.
