Collect…. The picture shows an example of a product that provides this function. Another key advantage of this system is that it does not require a raised floor at all. And redundancy can be maintained at low cost. The principle is simple. If you collect all the hot exhaust air and make it go away, you can’t have any hot-spots, and the equipment is always getting cool air from the CRAC. This system can get up to 8kW per rack, and is well suited to point racks, groups of racks, and retrofit applications. Beyond the 8kW range you must begin to bring the CRAC closer to the rack to overcome the problems associated with air collection and distribution…. 5- * Scavenging the hot exhaust air is one approach to handling increased power density.
