1. A system for cooling a plurality of information technology (IT) racks, comprising:
a first heat exchanger disposed at or near a hot aisle formed by the plurality of IT racks, the first heat exchanger including:
a first row including a first plurality of flat tubes; and
a second row including a second plurality of flat tubes in fluid communication with the first row;
a fan disposed in air communication with the first heat exchanger and configured to move air from the hot aisle through the first heat exchanger from the second row to the first row;
a single-phase fluid circuit coupled to and in fluid communication with the first heat exchanger, the single-phase fluid circuit circulating a single-phase fluid through the first heat exchanger from the first plurality of flat [[tube]]tubes to the second plurality of flat tubes;
a water circuit and
a second heat exchanger coupled between the single-phase fluid circuit and the water circuit.
