The UFRC (Under Floor Rack Cooler) replaces traditional CRAH units with smaller coolers located under each rack.  These are virtually linked together to provide redundancy and dynamic rack and pod level cooling control, all while using less energy.  Our patent pending solution eliminates the underfloor plenum with its inherent difficulties managing rack hot spots; the UFRC delivers cold air exactly where and when it is needed.  Importantly, the UFRC system is completely scalable to meet unknown future needs allowing more racks per pod, more pods in the data hall, and more kilowatts of cooling per rack.
