Chapter 2: Installation

Figure 2-1. Recommended installation.

NOTE: Placement of air barriers between the cold aisle/hot aisle is important. If the supply discharge is too close to the hot aisle, the conditioned supply air will be recirculated back to the intake in the hot aisle side of the cabinet before it has circulated through the equipment to be cooled.

Once the cabinet is removed from the shipping skid, roll it into position on the casters that are mounted to the bottom of the unit. Do not remove the shipping support brackets unless server racks are installed on each side of the Cold Row cabinet.

The cabinet is equipped with an adjustable foot at each corner to raise the cabinet off the casters after the unit is positioned in its operating location. The adjustable feet are also used for leveling and overall height correction. To adjust the height, use a flat-head screwdriver to turn the screws, located at the top of the four caster housings (accessed inside the front and rear corners of the cabinet per Figure 1-2). Raise or lower each foot until the cabinet is level and even with the adjacent equipment racks (see Figure 2-1).

2.5 Air Distribution

Air from the hot aisle is drawn into the rear of the Cold Row cabinet and passes through the fins of the cooling coil. The conditioned supply air discharges through the front of the cabinet (see Figure 2-2).

CRDX-W-FS-12KW, Black Box Cold Row DX, CRDX-W-FS-24KW, CRDX-A-FS-24KW, CRDX-A-FS-12KW specifications

The Black Box CRDX series consists of high-performance cooling solutions designed to maintain optimal temperature conditions in data centers and server rooms. Key models in this series include the CRDX-W-FS-12KW, CRDX-W-FS-24KW, CRDX-G-FS-12KW, and CRDX-A-FS-24KW. These units are engineered to provide efficient cooling while addressing the rising demands of modern IT infrastructure.

One of the standout features of the CRDX series is its cold row design. This configuration enables targeted cooling delivery directly to the equipment, enhancing efficiency and reducing energy consumption. The airflow management in these models ensures that cooled air is directed where it is needed most, minimizing hotspots and maximizing cooling performance.

Both the CRDX-W-FS-12KW and CRDX-W-FS-24KW models utilize advanced refrigerant-based cooling technology. These units are equipped with electronically commutated (EC) fans, which are highly efficient and quieter than traditional fan technologies. This innovation not only lowers operational costs but also creates a more comfortable environment within the data center.

The CRDX-G-FS-12KW model stands out for its hybrid capabilities, offering both chilled water and direct expansion cooling options. This versatility allows facility managers to choose the best cooling approach based on their specific requirements and current infrastructure. The hybrid system can optimize energy consumption and enhance cooling efficiency, contributing to lower operating costs.

Another noteworthy feature across these models is their intelligent controls and monitoring capabilities. Equipped with sophisticated sensors and control systems, operators can gain real-time insights into temperature fluctuations, humidity levels, and unit performance. This data aids in proactive maintenance and ensures that cooling systems are operating at peak efficiency.

The CRDX-A-FS-24KW, on the other hand, is designed with a focus on adaptability and scalability. This model can be integrated easily into existing network setups, making it an excellent choice for facilities that anticipate future growth or need to adapt to changing cooling demands.

Overall, the Black Box CRDX series exemplifies the latest advancements in cooling technology, offering innovative features designed to support high-density computing environments. With their efficient cooling capabilities, intelligent controls, and flexible design options, these models provide reliable solutions for data centers looking to enhance their cooling systems while reducing operating costs.
