NEO FREE BLOW – DX

The HiNova® NEO Free Blow series is a high-efficiency direct expansion (DX) cooling solution engineered specifically for mission-critical perimeter applications such as data centres, telecommunications hubs, industrial server rooms, and other high-load technical environments. Designed to integrate seamlessly into raised-floor installations, the system delivers powerful and reliable airflow directly into the IT environment for precise thermal management.

Built for uncompromising performance, the NEO Free Blow series features a dual refrigeration circuit paired with advanced scroll compressor technology, ensuring continuous operation even in partial fault scenarios. Each unit incorporates four compressors across two independent gas circuits, enhancing both cooling precision and system redundancy. The dedicated Electronic Expansion Valves (EEVs) modulate refrigerant flow intelligently in real time, maximizing energy efficiency and maintaining optimal operating conditions—even under low-load or low-ambient environments.

With an efficiency rating of up to 3.90, the NEO Free Blow range delivers outstanding operational cost reduction through optimized part-load performance and reduced compressor strain. The two-stage capacity control system allows compressors to operate individually or together, meaning cooling capacity automatically adapts to heat demand—resulting in improved performance, lower noise levels, and prolonged equipment lifespan. Reliable, stable, and built for continuous operation, the HiNova® NEO Free Blow is the ideal solution for facilities that cannot afford thermal compromise.

Key Features

• High energy efficiency– Efficiency ratings of up to 3.90 for reduced power consumption and operating costs.

• Dual refrigeration circuit– Independent circuits ensure redundancy and uninterrupted cooling during maintenance or partial failure.

• Scroll compressor technology– Low-noise, low-vibration operation with outstanding reliability and excellent part-load performance.

• Two-stage capacity control– Compressors modulate output on demand, maximizing system adaptability and extending lifespan.

• Electronic Expansion Valves (EEVs)– Real-time refrigerant optimization improves precision and boosts energy savings, especially under variable load.

• Smart control system– EEVs managed by an intelligent driver prevent overheating and maintain stable operation in all conditions.

• Raised-floor airflow design– Fans integrated within the raised floor ensure efficient cooling distribution directly to high-heat equipment.

Main Difference

The key difference that sets the HiNova® NEO Free Blow (DX Fixed Speed) apart from standard perimeter cooling systems is its dual-circuit, multi-compressor configuration with intelligent EEV-driven modulation, allowing the system to maintain peak thermal performance even during partial failure or maintenance. This delivers unmatched reliability and adaptability in mission-critical environments where uninterrupted cooling is essential.

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.
