Hong Kong Data Center Cooling Market Size & Share Analysis - Growth Trends And Forecast (2026 - 2031)

Hong Kong data center cooling market size in 2026 is estimated at USD 189.47 million, growing from 2025 value of USD 158.28 million with 2031 projections showing USD 466.12 million, growing at 19.72% CAGR over 2026-2031. This sustained expansion positions the Hong Kong data center cooling market as one of the fastest-growing country-level cooling arenas worldwide, supported by submarine-cable connectivity that anchors hyperscale deployments, an aggressive artificial-intelligence build-out, and regulatory incentives linked to carbon-neutrality goals. Hyperscale operators account for the bulk of new capacity additions, and their preference for rack densities above 30 kW accelerates the shift toward liquid technologies that outperform conventional computer-room air handlers (CRAH) and chiller loops. Cooling project timelines now intersect tightly with power allocation from CLP Power and HK Electric, forcing operators to prioritize solutions that keep power usage effectiveness (PUE) at or below 1.4. Competitive differentiation has therefore moved from basic availability to cooling efficiency, reliability in typhoon-exposed coastal zones, and the ability to integrate with district-cooling or heat-reuse schemes. Looking ahead, the Hong Kong data center cooling market is expected to balance a legacy air-cooling installed base with direct-to-chip cold plates, rear-door heat exchangers, and two-phase immersion environments that address forthcoming AI training clusters.

• By data center type, hyperscalers led with 44.85% of the Hong Kong data center cooling market share in 2025, while the same segment is projected to compound at 20.15% through 2031.
• By tier classification, Tier 3 facilities retained 62.55% revenue share in 2025, whereas Tier 4 builds are set to advance at a 20.6% CAGR to 2031.
• By cooling technology, air-based solutions commanded 65.20% share of the Hong Kong data center cooling market size in 2025, with liquid systems advancing at a 20.75% CAGR over the forecast period.
• By component, equipment accounted for 77.65% of the Hong Kong data center cooling market size in 2025, whereas services represent the fastest-growing piece at a 19.95% CAGR.

Hong Kong hosts 13 active submarine systems that land in Tseung Kwan O and other coastal precincts, allowing hyperscale operators to interconnect east-west traffic with minimal latency.^{[1]SUNeVision, “MEGA Plus Connectivity Advantages,” sunevision.com} The clustering effect created by these landing sites compresses land availability and raises rack-density expectations, which in turn compels the Hong Kong data center cooling market to specify higher chilled-water setpoints, larger distribution pipework, and modular heat-rejection blocks at inception. Operators such as SUNeVision design cooling plants capable of scaling from enterprise-style 12 kW racks to AI racks, surpassing 30 kW without ripping out existing infrastructure. Demand for instant connectivity also shortens leasing cycles, requiring chilled-water plants to achieve design PUE in under twelve months, a timetable that favors prefabricated cooling modules.

Global Switch stipulates PUE below 1.4 across its Asia-Pacific estate, and tenants that fall out of compliance face penalty clauses or renewal risks. Equinix HK4, meanwhile, achieved a 30% drop in cooling energy by integrating free-air economizer controls funded in part by CLP Power.^{[2]NVIDIA Corporation, “DGX B200 System Specifications,” nvidia.com}These contractual mechanisms push tenants to upgrade cooling coils, raise chilled-water temperatures, and adopt active aisle-containment or rear-door heat exchangers more quickly than their own capital-planning cycles would have dictated. The Hong Kong data center cooling market, therefore, benefits from predictable retrofit volumes driven by landlord compliance audits.

NVIDIA DGX B200 servers draw roughly 14.3 kW each, and eight chassis in a rack breach 30 kW, well beyond the thermal envelope of raised-floor air distribution. Vertiv’s CoolLoop trim cooler addresses these loads with supply-water temperatures at 40 °C that still deliver 70% annual energy savings compared with conventional CRAH deployments. The immediate implication for the Hong Kong data center cooling market is a non-negotiable shift toward liquid media that can transport 1,000-plus W per square meter without recirculation hotspots. Facility operators no longer treat liquid cooling as an optional overlay; it now constitutes the core strategy around which power, white-space layout, and service corridors are arranged.

Hong Kong’s Climate Action Plan earmarks USD 47 billion for territory-wide efficiency incentives, including accelerated depreciation on high-COP chillers and soft loans for waste-heat recovery loops. The Buildings Energy Efficiency Ordinance mandates decade-interval energy audits, a requirement that positions cooling upgrades as the most immediate route to compliance for data-center landlords. At the district level, the Kai Tak cooling plant uses seawater intakes to cut electricity use by 35% and save 85 million kWh annually.^{[3]Electrical and Mechanical Services Department, “Kai Tak District Cooling System,” emsd.gov.hk} These policy signals lock in a long-term growth runway for the Hong Kong data center cooling market as operators align expansion plans with territorial decarbonization milestones.

New feeder circuits require multi-stage sign-offs that can add 18 months to hyperscale build schedules, raising capitalized interest costs and delaying cooling-plant commissioning. Operators, therefore, push the Hong Kong data center cooling market toward ultra-efficient heat-exchanger loops, elevated chilled-water return temperatures, and variable-speed drives on pumps that flatten demand peaks inside constrained power envelopes. As electricity tariffs remain among the region’s highest, colocation tenants evaluate total landed-cost models where every incremental watt saved on cooling improves gross-margin sensitivity.

Immersion cooling requires technicians trained in dielectric-fluid handling, leak-detection regimes, and pressure-balanced tank installation. LiquidStack had to run dedicated certification tracks for local contractors to deploy its 2-phase systems that reach PUE 1.01. The scarcity inflates installation quotes and pushes project owners to bundle training packages with equipment orders, embedding a services premium into the Hong Kong data center cooling market that is reflected in the 20.4% CAGR forecast for the services segment.
