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. About HOLTOP HOLTOP (环都拓普) is a provider of precision environmental control solutions for data centers and critical facilities.

The units cover the emergency rescue center, operating rooms, ICUs and wards, providing a safe, clean and energy-saving air environment for critical care in northern Shandong. Binzhou Medical University Hospital is a Grade III-A comprehensive hospital and one of Shandong’s first seven provincial regional medical centers. The new project has a total construction area of about 75,000 square meters and 400 emergency beds, making it a landmark critical care project in northern Shandong. The units adopt heat pump plus liquid circulation dual heat recovery technology. The first stage recovers energy through liquid circulation, and the second stage further utilizes exhaust air energy through a heat pump cycle, effectively avoiding winter frosting and blockage problems common in northern China and ensuring stable year-round operation. With dual-stage heat recovery, unit energy efficiency can reach 4.8. Compared with conventional air-conditioning systems, annual HVAC energy consumption can be reduced by more than 70%, supporting green and low-carbon operation of large public hospitals. Fresh air and exhaust air are completely physically isolated, preventing pollutants and pathogens from entering the fresh air side. Multi-stage filtration and electronic purification progressively improve supply air cleanliness, meeting strict infection-control requirements in operating rooms, ICUs and emergency departments. The integrated design combines heat pumps, liquid circulation, fresh air pretreatment, multi-stage filtration and electronic purification, reducing on-site installation work by about 30%. It adapts to limited machine room space and complex construction conditions in new-build and renovation projects. The project is a benchmark practice for HOLTOP in hospital HVAC and validates its delivery capability for dual heat recovery, cross-infection prevention and integrated design in large northern general hospitals. HOLTOP will continue to provide professional, intelligent and low-carbon HVAC solutions for healthcare institutions. Media Contact: Nancy Yin nancy@holtop.com.cn +86 19831815808

The catalog is compiled in accordance with Beijing’s implementation measures for the Energy Conservation Law of the People’s Republic of China. It is organized by the Beijing Energy Conservation and Environmental Protection Center and selects entries through solicitation, expert review, and public announcement. The 2026 edition includes 33 energy-saving technologies and products covering building energy efficiency, industrial energy efficiency, data center energy efficiency, and smart energy management systems. It aims to promote energy conservation as the “first energy” and encourage energy-consuming entities to adopt advanced, applicable energy-saving technologies. HOLTOP’s selected product is a flagship unit built on the company’s self-developed core air heat recovery technology. It features a 3D plate heat exchanger with dual independent air ducts. Based on non-contact heat transfer, the system efficiently recovers energy between fresh air and exhaust air while avoiding the risk of cross-contamination. The unit uses high-density foam insulation to improve thermal performance and help inhibit condensation. A fresh air bypass structure allows natural fresh air to be fully utilized during transition seasons, further improving energy savings and extending the service life of core components. The product is suitable for high-quality buildings and applications with high indoor air quality requirements. HOLTOP said the inclusion reflects authoritative recognition of the product’s energy-saving performance. In recent years, the company has prioritized R&D and technological innovation, investing in test platforms and advancing heat recovery technologies. Other HOLTOP products have also received industry recognition, including selection for the Chinese Association of Refrigeration’s energy-saving and environmental protection catalog and Beijing’s new technology and new product lists. Looking ahead, HOLTOP said it will remain committed to its mission of “making air treatment healthier, more comfortable and energy-efficient,” and will continue developing energy-efficient HVAC products to support green, low-carbon development in the industry. About HOLTOP HOLTOP specializes in air treatment technologies, with a focus on heat recovery, energy efficiency, and environmental protection.
