APC by Schneider Electric has released its InRow OA and Refrigerant Distribution Unit (RDU) pumped refrigerant cooling system. The APC InRow OA expands APC’s InRow product line by providing an overhead, energy efficient, refrigerant-based cooling solution for data center environments.

Ideal for medium and high density applications, the new APC InRow OA captures up to 27kW of hot IT exhaust air at the source, neutralizes it and discharges cool, ambient air to the IT space. The OA includes integrated thermal containment, which eliminates mixing of hot and cold airstreams-improving cooling predictability. Modular construction, variable-speed fans, and active response controls are all integrated into one high efficiency system. The overhead design requires zero whitespace, because it can be mounted on a rack or suspended from the ceiling above the hot aisle, improving flexibility and the ability to adapt to existing data center environments.

This refrigerant-based system has been developed to eliminate the threat from water leaks in close proximity to IT equipment. The refrigerant used in this modular, pumped system is R134a, a non-toxic solution that poses no threat to IT equipment in the event of a leak, and has no Ozone depletion potential.

The RDU is a refrigerant distribution unit capable of providing 160kW of heat rejection to the APC InRow OA cooling units. Response controls are integrated into the highly efficient variable volume pumping system. The RDU has the ability to modulate capacity from 0 to 100 percent with no minimum loading requirements and may be placed in the IT environment or in an adjacent location to further increase whitespace utilization for IT equipment.
