DUO – DX/CW

HiNova® CRAC Units are purpose-built for mission-critical environments, offering advanced Dual-Cooling technology that guarantees uninterrupted operation, even in the event of a primary system failure. Designed with built-in redundancy, intelligent water flow control, and free cooling capability, these units deliver precise temperature management while minimizing energy costs. Compact yet high-performing, HiNova® CRAC Units fit seamlessly into demanding spaces, including data centers, industrial sites, healthcare facilities, and commercial buildings.

The dual independent cooling circuits—available in either Direct Expansion/Chilled Water (DX/CW) or Chilled Water/Chilled Water (CW/CW) configurations-allow automatic switchover between cooling sources, ensuring continuous, reliable performance. The intelligent water flow regulation system monitors real-time pressure differentials, dynamically adjusting valves to optimize coolant delivery without manual intervention. Furthermore, the secondary chilled water coil can operate as a free cooling coil, supplementing cooling capacity during high load conditions while improving energy efficiency and reducing operational costs.

With HiNova® CRAC Units, organizations achieve both operational reliability and energy-conscious performance in a compact design that maximizes flexibility and adaptability.

Main Difference

Unlike conventional CRAC units, HiNova® CRAC Units with Dual-Cooling technology combine two fully independent cooling circuits with intelligent water flow regulation and optional free cooling functionality. This ensures uninterrupted cooling performance, built-in redundancy, and energy-efficient operation-making them ideal for mission-critical environments where reliability, precision, and efficiency are non-negotiable.

Airflow Configurations

HiNova designs and manufactures units in multiple airflow configurations to suit a variety of installation environments and cooling requirements. Whether Upflow, Downflow, or Displacement, each configuration is engineered to deliver optimal air distribution and reliable performance.
