Beijing, China – November 6, 2026 – As the digital economy accelerates, data centers—the core carriers of computing power infrastructure—are under growing pressure to stay cool, efficient and reliable. HOLTOP today highlighted its room-level air-cooled precision air conditioning units, a comprehensive cooling solution engineered to optimize PUE, ensure uninterrupted operation and reduce lifecycle operating costs.
Precision Temperature & Humidity Control
With temperature control accuracy of ±1°C and humidity control of ±5%, the units automatically adapt to fluctuating IT loads and extreme outdoor conditions around the clock, maintaining a stable environment for sensitive electronic equipment.
Robust Design for All Climates
Each unit features a high-performance fully enclosed flexible scroll compressor with low vibration and low noise, integrated with multiple safety protections including over-pressure, over-current, anti-freeze and overload safeguards. An optional low-temperature package enables stable operation in outdoor conditions as low as -40°C (fluorine pump models), making the units suitable for cold regions and demanding climates.
Energy Efficiency & Lower PUE
Standard high-efficiency EC fans maintain over 85% energy efficiency even at low speeds, while high-precision electronic expansion valves and enhanced heat-exchange structures boost cooling performance. With the optional free-cooling module, compressors can be shut down during transition seasons and cool nights—the unit then consumes only 10–20% of the energy of conventional compressor cooling, significantly cutting data center energy bills and carbon footprint.
Intelligent, Simplified Management
A 7-inch bilingual touchscreen displays real-time operating data, and units support MODBUS, TCP/IP and SNMP for seamless integration with monitoring platforms. Up to 32 units can be networked per machine room for automatic rotation, load balancing, early fault warning and self-diagnostics—shifting maintenance from reactive to predictive.
Flexible Deployment
Supporting mainstream airflow configurations (raised floor, ceiling plenum, direct-blow), the compact units fit both new standard data centers and retrofit or micro-zone cooling projects, with minimal civil modification required.
HOLTOP's room-level air-cooled precision air conditioning delivers precise control, robust quality, energy savings and intelligent O&M, providing a one-stop reliable cooling solution for data centers across industries.
