AI-Driven Cooling Surge Reshapes India’s Data-Center Landscape
4/29/2026, 12:17:00 PM
Background: AI Workloads Shift Bottlenecks to Thermal Management
The rapid adoption of artificial-intelligence (AI) workloads is shifting the primary constraint on Indian data centers from electricity supply to heat dissipation. As AI models demand higher compute density, advanced cooling solutions have become essential for operational efficiency. Analysts project $2-2.5 billion of thermal-management investment over the next four to five years.
Key Cooling Players Position for Growth
Three Indian firms dominate the cooling market. KRN Heat Exchanger supplies chillers and dry-air coolers to major HVAC integrators and recently won a low-cost bid for a client with over 90 SKUs, targeting 50 % of the domestic data-center heat-exchanger market. Voltas leverages its mechanical-electrical-plumbing (MEP) vertical for data-center projects. Blue Star is moving into high-margin liquid-cooling, developing in-house models within 12 months and seeking international partners.
Investment Outlook and Market Projections
India’s data-center capacity, about 1.5 GW today, is projected to reach 3-3.5 GW by 2029-2030 and 4 GW by 2030, implying roughly Rs 1.5 lakh crore of new investment. The cooling segment is expected to grow at a 26.3 % CAGR (2026-2035) and exceed $12 billion in value. KRN’s market cap is INR7,755 crore with a P/E of 121.13, ROE 20.8 % and 65 % YoY net-profit growth in Q3 FY26. Voltas trades at a P/E of 82-99 x. Blue Star’s market cap is INR38,890 crore, RoCE 47.5 %, ROE 26.2 % and a 7.4 % one-year total return.
Official Statements & Analyst Views
Two equity analysts rate KRN Heat Exchanger a “Strong Buy”, citing its expanding order book and market-share target. They add that current equity multiples for the three firms already reflect expectations of sustained AI-driven demand and rapid technology adoption.
Risks and Counterpoints
The sector faces execution and market risks. KRN’s six-fold capacity expansion and market-share goal rely on large contracts and sustained demand. Voltas’ growth ties to broader construction cycles, making it vulnerable to infrastructure-spending swings. Blue Star’s move to liquid cooling depends on successful product development and partnerships, exposing it to technical or timing setbacks. High valuation multiples—especially KRN’s P/E above 115—could trigger price corrections if demand eases or competition sharpens. Further uncertainties include global semiconductor supply-chain disruptions and shifting investment strategies of hyperscale cloud providers, which may affect capital allocation to cooling.
Future Developments and Outlook
Industry participants expect continued capacity expansion, with Blue Star’s liquid-cooling solutions slated for market launch within a year. Government initiatives promoting domestic data-center construction and broader digitalization trends should sustain demand for advanced thermal-management technologies. If AI workload growth materializes, the cooling market could stay a primary driver of investment and profitability for the highlighted firms over the next decade.
