APC by Schneider Electric, has released the InRow OA and Refrigerant Distribution Unit (RDU) pumped refrigerant cooling system. The InRow OA expands APC’s leading 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 APC InRow OA captures up to 27 kW 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.
