• a chassis having an upper end and a lower end spaced apart from one another in a vertical direction;
• at least one heat exchanger connected to the chassis, the at least one heat exchanger being disposed vertically at least in part between the upper and lower ends of the chassis, each of the at least one heat exchanger comprising:
• a cooling coil for circulating a cooling fluid therethrough;
• and
• a plurality of fins connected to the cooling coil, the fins being spaced from one another to allow air flow therebetween;
• and
• at least one lower bracket connected to a lower end portion of the chassis, each of the at least one lower bracket being a single piece of sheet metal bent into shape and comprising a supporting wall extending frontward from the lower end portion of the chassis, the supporting wall being configured to receive at least in part a lower end of the data center rack thereon such that, in use, the supporting wall is disposed between the lower end of the data center rack and a support surface.
