IN-ROW COOLING – DX

The HiNova® In-Row 600 is engineered to meet the demands of high-density server racks and modern digital infrastructure, delivering a precise and energy-optimized cooling strategy directly within the rack row. Designed specifically for facilities where reliability, scalability, and space efficiency are critical, this Direct Expansion (DX) cooling solution ensures targeted thermal management without the energy losses commonly associated with traditional room-based cooling.

Compact yet exceptionally powerful, the In-Row 600 integrates seamlessly into standard 600mm-wide, 1200mm-deep enclosures, redirecting cool air evenly across the entire front surface of adjacent server racks to eliminate hotspots and maintain uniform rack-level temperatures. The unit’s internal layout is optimized for serviceability, with unobstructed access to all critical components and flexible cable and fluid connection points from both the top and bottom-simplifying installation in dense IT environments.

At its technological core, the HiNova® In-Row 600 features high-efficiency DC inverter compressors and variable-speed EC fans, providing continuous cooling capacity modulation between 30% and 100% based on real-time thermal demand. This ensures that the system delivers only the required cooling capacity at any moment, dramatically improving energy efficiency and lowering operational costs-especially under partial load conditions.

Intelligent environmental control is handled by an advanced onboard controller, offering real-time visibility into temperature, humidity, energy consumption, and component performance. The system integrates smoothly with Building Management Systems (BMS) and supports both local and remote configuration, enabling precise logic-based operation, airflow balancing, pressure management, and on-demand capacity control. Optional upgrades include dual power inputs with automatic transfer switching and backup power for the controller, ensuring full operational continuity during unexpected power disturbances.

The HiNova® In-Row 600 is available in online and in-line configurations, offering installation flexibility based on cooling strategy—whether isolating hot/cold aisles or operating from within the rack enclosure itself. To support a wide variety of data center layouts, the condenser can be configured for vertical or horizontal mounting, even over extended distances from the indoor unit.

Built for performance, efficiency, and sustainability, the system operates using R410A refrigerant, coupled with Electronic Expansion Valves (EEVs) and microchannel coils to optimize refrigerant charge and maximize heat exchange capacity. This design supports up to 25% energy savings, while ensuring long-term reliability and reduced environmental footprint.

With 24/7 precision thermohydrometric control, durable construction, superior airflow delivery, and support for high-power equipment densities, the HiNova® In-Row 600 unlocks a smarter, more scalable approach to digital infrastructure cooling-ideal for data centers, edge computing sites, telecom facilities, and colocation environments where uptime, efficiency, and space optimization are non-negotiable.

Main Difference

The main difference that sets the HiNova® In-Row 600 apart from traditional cooling systems is its rack-level thermal delivery strategy. Instead of cooling the entire room and hoping airflow reaches the equipment efficiently, the In-Row 600 places cooling exactly where heat is generated-directly between server racks. By modulating real-time cooling capacity and directing airflow precisely across the front of high-density servers, it delivers maximum efficiency, higher cooling effectiveness, and significantly reduced energy usage, even under demanding IT loads.

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.
