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.

RAYONG, Thailand — HOLTOP has deployed its water-cooled direct expansion (DX) air handling solution at the Zhonglian Thailand Rayong Data Center, a planned 203 MW AI and computing campus in Thailand’s Eastern Economic Corridor (EEC). The project is invested and operated by Stratus Technology, a subsidiary of China Zhonglian Data Group. It supports general IDC colocation, cloud hosting, AI large-model and HPC workloads, and cross-border enterprise/government line transit. For AI and high-density racks, the facility requires continuous heat removal and room-level control within ±2°C and ±10% RH. It also requires 7*24 high-load energy efficiency and remote operation and maintenance (O&M) to reduce overseas site costs. HOLTOP’s solution uses rooftop-integrated water-cooled DX air handling units (AHUs). The design eliminates a dedicated indoor AHU room, applies rain and corrosion protection for tropical storms and coastal salt spray, and requires only ductwork connection before commissioning. Precision control is achieved through high-precision sensors and intelligent control algorithms that respond to load changes and help avoid local hot spots and temperature/humidity fluctuations. For air quality, the units provide pre-treated fresh air and chemical filtration for sulfur- and nitrogen-based compounds. Treated air meets the ISA S71.04 G1 severity level for gas-phase corrosion. The water-cooled heat rejection architecture is less affected by outdoor dry-bulb temperature than air-cooled systems, supporting stable condensing conditions and efficient operation in Thailand’s hot climate. This helps reduce system Power Usage Effectiveness (PUE) under 7*24 high-load operation. The smart management system collects operating status, control parameters and energy data, and supports remote monitoring, alarm notifications, multi-unit cluster control and automatic logs. This reduces on-site inspections and simplifies troubleshooting for overseas teams. The project validates HOLTOP’s delivery capability for high-precision, energy-efficient HVAC in tropical, high-humidity AI data centers.
