Asetek has built a new type of liquid cooling adapter that can be fitted onto existing servers. The big win here is that the adapters cool the servers more efficiently than the air conditioning that’s typically used. That means a customer can shut down the air conditioning systems and run a more efficient, greener data center, saving money in the process. It can take a couple of days to outfit all of the servers in a large data center with the Asetek gear, and there is additional hardware to buy. “But we promise that within the first year of operation, you will have made your money back from the energy savings,” Eriksen says.
