AirTrunk Hong Kong Hyperscale Data Center Expansion (35MW)
Status: Operational | Location: Tsuen Wan
Project Overview
AirTrunk Hong Kong Hyperscale Data Center Expansion (35MW) is a significant digital infrastructure development aimed at strengthening Hong Kong’s role as a leading connectivity and cloud services hub in the Asia-Pacific region. Developed by AirTrunk, a major hyperscale data center provider operating across Asia-Pacific markets, the project focuses on expanding high-capacity, enterprise-grade infrastructure to meet rapidly increasing demand from hyperscale cloud providers, technology companies, financial institutions, and digital service platforms. The 35MW expansion enhances AirTrunk’s operational footprint in Hong Kong by delivering scalable and energy-efficient data center capacity designed to support cloud computing, artificial intelligence workloads, digital content delivery, and large-scale enterprise applications. Strategically located within one of Asia’s most important financial and telecommunications gateways, the facility benefits from strong international submarine cable connectivity, low-latency regional access, and proximity to major business districts and internet exchange ecosystems. The project incorporates advanced cooling systems, high-density rack configurations, resilient power infrastructure, and enhanced security systems to ensure operational reliability and performance for mission-critical workloads. Sustainability and energy optimization are key priorities within the development, with AirTrunk integrating efficient cooling technologies, power management solutions, and environmentally responsible operational practices to reduce carbon intensity and improve long-term efficiency. The expansion also supports Hong Kong’s growing digital economy by enabling increased cloud adoption, hybrid IT deployments, fintech innovation, and cross-border digital services throughout the Greater Bay Area and broader Asia-Pacific market. In addition to strengthening regional digital infrastructure resilience, the project contributes to economic growth through investment in construction, engineering, telecommunications, and technology services. As demand for hyperscale capacity continues to rise across Asia, the AirTrunk Hong Kong Hyperscale Data Center Expansion positions Hong Kong as a strategically important destination for next-generation digital infrastructure and large-scale cloud ecosystem development.
