NERG-G – DX

The HiNova® NER-G Precision Air Conditioner is a next-generation cooling solution engineered to deliver exceptional energy efficiency, reliability, and high-performance climate control. Designed for mission-critical environments where downtime is not an option, the NER-G ensures consistent cooling with a high Coefficient of Performance (COP) of up to 4.5, dramatically reducing energy consumption and long-term operating costs.

Built with a sophisticated dual-compressor architecture-featuring one fixed-speed scroll compressor and one BLDC inverter compressor-the NER-G intelligently adapts to cooling demand in real time. This hybrid system optimizes part-load efficiency and provides precise temperature and humidity regulation, keeping environmental conditions consistently stable even under fluctuating heat loads.

The unit’s dual refrigerant circuits provide built-in redundancy to guarantee uninterrupted performance. Maintenance can be performed on one circuit while the other remains operational, ensuring continued uptime in facilities where cooling cannot be compromised. Electronic Expansion Valves (EEVs) further enhance accuracy by precisely regulating refrigerant flow for maximum thermal performance.

To support simplified serviceability and operational continuity, all refrigeration components are housed in an independent service compartment, enabling fast, safe, and obstruction-free access for technicians. Integrated smart diagnostics and monitoring allow real-time performance tracking and predictive maintenance planning-extending equipment lifespan, preventing failures, and minimizing total cost of ownership.

Whether deployed in a data center, telecommunications hub, laboratory, medical facility, industrial plant, or control room, the NER-G provides precise, reliable cooling with ultra-low noise, long-term durability, and unbeatable part-load efficiency. Its cutting-edge BLDC inverter technology, rugged reliability, and intelligent control systems make it the ideal solution for energy-conscious organizations requiring precision-focused climate management.

Highlights

The defining advantage of the NER-G series is its intelligent dual-compressor configuration. Unlike traditional single-compressor systems, the NER-G combines a fixed-speed scroll compressor with a highly efficient BLDC inverter compressor, enabling near-perfect load adaptation, dramatically reduced energy consumption, and superior performance during varying heat demands. When cooling demand rises, both compressors operate together; when demand drops, the inverter compressor modulates to maintain efficiency. Combined with dual refrigerant circuits and real-time diagnostics, the NER-G delivers a unique combination of Redundancy + Precision + Energy Savings-making it one of the most advanced HVAC precision cooling systems in its class.
