HICOOL WALL – DX

The HiNova Cool Wall is a state-of-the-art chilled water and direct expansion (DX) cooling solution, specifically engineered to meet the demanding thermal management requirements of modern, high-density data centres. Designed for efficiency, scalability, and reliability, the Cool Wall optimizes airflow to deliver precision cooling across cold aisles, minimizing air travel paths and significantly improving energy performance. Its innovative flooded aisle concept ensures consistent, even airflow at all rack heights, eliminating the need for a raised floor and reducing infrastructure costs.

With a modular, stackable design, the HiNova Cool Wall adapts to various data centre layouts, conserving valuable floor space while offering flexible capacity expansion and redundancy. Fully front-accessible components simplify maintenance, while dual-circuit cooling technology guarantees uninterrupted operation even during partial load conditions or system maintenance.

Main Difference

Unlike traditional air handling units or ceiling-mounted fan coils, the HiFan Wall Unit combines compact wall-mount design with high airflow efficiency, allowing for effective cooling without occupying floor or ceiling space. Its fan wall configuration ensures superior air distribution and quieter operation, making it ideal for spaces where comfort, performance, and minimal noise are critical.

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.
