The push for efficient data center cooling
Data centers require dependable cooling infrastructure to maintain operating temperatures, protect sensitive IT equipment, and support uninterrupted computing operations. The growing adoption of cloud services, artificial intelligence (AI), high-performance computing, and digital applications is increasing the need for effective thermal management.
As data center capacity expands, operators face pressure to balance cooling performance with electricity consumption and operational reliability. Chiller systems are becoming an important part of this investment as facilities seek to support higher computing densities and improve cooling efficiency.
Key factors influencing market growth include:
- Hyperscale data center expansion: Large-scale facilities require reliable cooling capacity to support growing server installations and increasing computing workloads.
- Rising energy efficiency requirements: Operators are prioritizing cooling equipment that can help reduce energy consumption and improve overall facility efficiency.
- Increasing data traffic: Cloud computing, digital services, and AI applications are raising the demand for data processing and supporting infrastructure.
- Thermal management requirements: Higher equipment densities increase the importance of maintaining stable operating temperatures and dependable cooling performance.
Where the market is headed
According to FMI, the data center chillers market is expected to grow from USD 1.7 billion in 2025 to USD 3.9 billion by 2035, registering a CAGR of 9.0%.
This growth reflects the increasing importance of cooling infrastructure in data center development. As operators expand computing capacity, the selection of appropriate chiller technologies will remain closely linked to facility design, cooling requirements, energy performance, and operating conditions.
The market outlook also highlights the importance of matching cooling equipment to different data center configurations. Air-cooled and other chiller technologies offer distinct operational characteristics, making system selection an important consideration for developers and facility managers.
What leads the market
FMI identifies air-cooled chillers as the leading product category and scroll chillers as the leading technology segment in the data center chillers market.
- Air-cooled chillers — 39.6% share: Air-cooled systems are projected to account for 39.6% of the market in 2025. Their contribution reflects the importance of cooling solutions that can be configured around facility requirements and site conditions.
- Scroll chillers — 28.4% share: Scroll chillers are expected to hold a 28.4% share of the technology segment in 2025, highlighting their role in the range of cooling solutions available to data center operators.
These segment shares indicate that market demand is distributed across different cooling configurations and technologies. The appropriate choice depends on factors such as cooling load, facility layout, operating efficiency, maintenance requirements, and environmental conditions.
The challenge: balancing cooling capacity and energy consumption
Data center operators must maintain reliable cooling while managing operating expenses and increasing computing demands. Cooling infrastructure needs to accommodate changes in workloads without compromising equipment performance.
Several considerations influence chiller selection and deployment:
- Energy performance: Cooling equipment must meet facility requirements while supporting efforts to control electricity consumption.
- Scalability: Growing data center capacity requires cooling infrastructure that can accommodate changing thermal loads.
- Operational reliability: Equipment performance and maintenance planning are essential to reducing the risk of cooling disruptions.
- Site-specific requirements: Climate, available space, facility configuration, and cooling design influence the suitability of different chiller systems.
As data centers support increasingly demanding digital workloads, cooling strategies will need to account for both immediate thermal requirements and future capacity expansion.
What this means for data center operators and cooling equipment suppliers
- Prioritize cooling efficiency. Operators should evaluate chiller systems based on cooling performance, energy requirements, maintenance needs, and long-term operating costs.
- Align equipment with facility design. Air-cooled and scroll chiller configurations should be assessed against site conditions, cooling loads, and infrastructure requirements rather than selected on capacity alone.
- Plan for increasing computing demand. Data center developers and facility managers should consider how cooling systems will accommodate future capacity additions and evolving thermal management needs.
- Focus on reliable operations. Suppliers that address uptime requirements, service support, and operational performance can better respond to the needs of data center customers.
- Track technology and infrastructure investment. As hyperscale facilities and digital workloads expand, cooling equipment manufacturers should monitor changing customer requirements and the growing emphasis on energy-efficient data center infrastructure.
Analyst view
The data center chillers market is entering a period of sustained expansion as digital infrastructure investment increases. With the market projected to reach USD 3.9 billion by 2035 at a CAGR of 9.0%, cooling performance and energy efficiency will remain important considerations for equipment manufacturers, data center developers, and facility operators.
Air-cooled chillers, with a projected 39.6% market share, and scroll chillers, with a projected 28.4% share of the technology segment, represent important parts of the market landscape. Suppliers that align their offerings with facility-specific cooling requirements, operational reliability, and efficiency objectives will be well positioned to compete as data center infrastructure continues to evolve.
