From the Service>Blower menu, you may access screens to view and adjust the blower speed parameters.

Temp Zone Setup

Figure 4-46. Temperature zone setup screen.

If your unit is configured for zone temperature control, Blower>Temp Zone display screens are available for the upper, middle, and lower fan. These screens allow you to adjust minimum and maximum fan speed settings and modify the fan speed proportional/ integral (PI) control response parameters. The variable dampening value, used with Variance From Average fan speed control (see Section 4.4.4.1), adjusts the effect of the variance on the final fan speed.

Blower Setup

Figure 4-47. Blower setup screen.

The blower fans will operate at the Dehum Fan Speed setting during dehumidification. Dehumidification fan speed is limited to the most restrictive value between the factory preset minimum and maximum, the temperature zone minimum and maximum, and the speed setting for the operating mode. The higher minimum value is the low speed limit and the lower maximum value is the high speed limit.

Ex: If the Dehum Speed is set to 60% in the Blower Setup screen and the maximum speed for the lower temperature zone fan is set to 75% and the factory-set maximum fan speed is 90%, the fans will run at 60% during dehumidification.

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.
