Overview
Product overview
The HPE Adaptive Rack Cooling System is a supplemental cooling system for data centers. It is a liquid-
to-air heat exchanger and fan system that removes heat generated by rack-installed IT equipment. The
HPE Adaptive Rack Cooling System is connected to adjoining racks with baying brackets and front and
rear extensions, creating a cold aisle and hot aisle air plenum. Hot air from the IT exhaust is pulled
through the HPE Adaptive Rack Cooling System, cooled with the heat exchanger that is connected to
facility water, and the cooled air is then returned to the inlet of the servers. The HPE Adaptive Rack
Cooling System is offered in four configurations using either HPE ARCS 42U 600x1600mm Racks or HPE
ARCS 48U 600x1600mm Racks.
NOTE: The HPE Adaptive Rack Cooling System supports both HPE ARCS 42U and 48U 600x1600mm
Racks. For the following front elevation views, the HPE ARCS 48U 600x1600mm Rack is shown. The
HPE Adaptive Rack Cooling System is shown without doors for better viewing of components.
The thermal airflow illustrations show a top view of the HPE Adaptive Rack Cooling System and HPE
ARCS 42U/48U 600x1600mm Racks.

The airflow of the HPE Adaptive Rack Cooling System fully supports the industry standard front-to-back
cooling—cold air pulled into the front of the server and warm air expelled out the rear of the unit. All
devices receive adequate and evenly distributed cool air regardless of the mounting position within the
rack. The HPE Adaptive Rack Cooling System distributes precisely cooled and targeted air flow evenly
across the front of the IT equipment. The HPE Adaptive Rack Cooling System and rack extensions
channel warmed air from the rear of the IT equipment into the side-mounted or center-mounted HPE
Adaptive Rack Cooling System cooling unit. From there, it is cooled and recirculated to the front of the
equipment stack.
A 6U facade comes in the HPE ARCS 48U Air Rack Installation Kit, and you can place it on top of the
HPE Adaptive Rack Cooling System to make the HPE Adaptive Rack Cooling System the same height as
the HPE ARCS 48U 600x1600mm Racks. The following illustration shows a single-unit configuration with
the 6U facade in place on the HPE Adaptive Rack Cooling System and the HPE Adaptive Rack Cooling
System doors in place.
