Escalating demands in technology and breakthroughs in performance limits have driven manufacturers to seek cooling solutions with ever greater capacities and smaller footprints. In particular, the computing sector - both servers and datacenters - has a pressing demand for better cooling solutions. The importance of coolers in present server/datacenter market has become paramount with the increasing ambient temperatures they operate in. Moreover, exigencies for more and enhanced cooling technologies in datacenters are expected with the growing demands of better computing performances. Today, modern datacenters operate at an ambient temperature of 35 ° C (Free cooling) to achieve the highest level PUE of below 1.2.
