HPE Adaptive Rack Cooling System QuickSpecs
A closed loop cooling system that removes the high levels of heat generated by today’s servers, mass storage, and core networking hardware
The HPE Adaptive Rack Cooling System allows for simultaneous cooling of up to four racks and 150 kW of IT capacity when used in conjunction with the HPE Adaptive Rack Cooling System 42U or 48U racks.
-
HPE Adaptive Rack Cooling System is designed to complement any new or existing data center by enabling computing power growth without adding to the heat load in the data center. In addition, by allowing equivalent cooling capacity as commodity DLC, the HPE Adaptive Rack Cooling System will extend, considerably, the life of your data center. The horizontal air flow of the HPE Adaptive Rack Cooling System fully supports industry-standard front-to-back cooling designs and standard server dimensions. Additionally, the implementation of variable speed fans within the system enables improved energy efficiencies while providing all devices the right volume of airflow, regardless of the mounting position or workload.
