DX Air-Cooled In-Row Precision Air Conditioner is a mainstream type of in-row precision cooling unit. It adopts direct expansion refrigeration cycle and rejects heat via outdoor air-cooled condensers. Installed between server rack rows, it delivers close-range cooling for high-density IT hardware. No chilled water piping or chillers are required; indoor units connect to outdoor air-cooled condensers only through copper refrigerant pipes for easy installation. Widely applied in small & medium server rooms, containerized modular data centers and legacy room retrofits, it eliminates rack hotspots with short air supply paths and maintains precise, stable temperature & humidity all year round.

Advantages

● Waterless System for Fast Installation

No chillers, cooling towers or water pipelines needed, cutting civil engineering and piping construction work to shorten delivery time and avoid equipment damage caused by water leakage.

● Close-Coupled DX Cooling to Eliminate Hotspots

Short air supply path between racks sends cold air directly to server air inlets, perfectly matching high-load per rack computing hardware and avoiding overheating shutdowns in high-density computer rooms.

● Independent Unit Design for Flexible Expansion

Each indoor & outdoor unit set operates independently. Extra units can be added with newly increased racks, and N+1 redundant backup is supported for phased construction data centers.

● Full Variable Frequency Configuration to Cut Operating Cost

Standard equipped with variable frequency compressors and EC variable-speed fans with high sensible heat ratio. Optional refrigerant pump free cooling module utilizes outdoor cold air for free cooling in transition seasons to reduce overall PUE.

● Integrated Intelligent Control for Easy O&M

Built-in independent PLC control system supports local touch screen operation and remote DCIM connection. It monitors temperature, humidity, system pressure and fan status in real time, triggers automatic fault alarms and balances loads through group linkage control.

Application Scenario

● Small & medium enterprise server rooms, government & enterprise core equipment rooms

● Integrated containerized modular data centers, edge computing rooms

● Telecom base station equipment rooms, 5G edge computer rooms

● Thermal retrofits of legacy server rooms, new facilities without chilled water infrastructure
