By chiller type, water-cooled chillers lead at 46% share, while free-cooling and economizer-assisted chillers are the fastest-growing type at about 12.6% CAGR. By compressor technology, oil-lubricated centrifugal machines lead at 32%, and magnetic-bearing / oil-free centrifugal technology is the fastest-growing at about 14.2% CAGR. Large plants of 1,000-3,500 kW form the largest capacity band (38%), while high-capacity hyperscale systems above 3,500 kW grow fastest. Chilled-water systems with water-cooled heat rejection are the largest cooling configuration (40%); liquid-cooling-integrated architectures are the fastest-growing at about 16.5% CAGR. Hyperscale facilities are the largest end-user segment (38%), with edge and other facilities expanding fastest from a small base at about 11.4% CAGR.
Growth is driven by rising IT power density, AI and high-performance computing, efficiency and PUE pressure, and investment in digital infrastructure. Key trends include magnetic-bearing and variable-speed compressors, higher chilled-water temperatures that extend free-cooling hours, modular and packaged plants, warm-water integration with liquid cooling, and AI-assisted plant optimization connected to DCIM and BMS platforms. The principal challenges are high capital cost, complex plant design and commissioning, water-use scrutiny, refrigerant regulation, skilled-labor shortages, lead-time pressure and power availability constraints in several countries.
The competitive landscape is led by diversified HVAC majors - Johnson Controls, Trane Technologies, Carrier Global and Daikin Industries - alongside data center infrastructure specialists Vertiv and Schneider Electric and cooling specialists Mitsubishi Electric (Climaveneta, RC) and STULZ, with competition centered on efficiency, delivery capacity, service reach and chip-to-chiller integration. Looking ahead, the market enters 2026 as a structurally growing, mission-critical category in which AI-driven density, sustainability mandates and continuous capacity expansion are expected to sustain chiller demand through 2030.
