Water-Glycol Cooling Gains Momentum as EV and Automation Markets Scale Up
Water-glycol based electric drive units are emerging as a preferred solution for e-mobility and industrial applications due to their superior thermal management performance. As electric powertrains operate under higher loads and voltage levels, traditional cooling systems are proving inadequate. Water-glycol coolants address this challenge by maintaining stable temperatures in motors, power electronics, and inverters-enabling higher power density, extended component life, and reduced maintenance cycles.
Government-led zero-emission mandates, stricter efficiency regulations, and growing investment in electrification infrastructure have further accelerated market penetration. OEMs are shifting decisively toward integrated, thermally optimized drive units that support fast charging, high-performance acceleration, and extended operating cycles.
BEV Segment Dominates with 64% Market Share in 2025
Battery Electric Vehicles (BEVs) are expected to account for 64% of the market in 2025, underscoring their reliance on advanced thermal management systems. Water-glycol cooling enhances BEV efficiency by stabilizing temperature extremes during high-load operation, fast charging, and regenerative braking. As global EV manufacturing scales up, the integration of thermally controlled drive units is becoming standard across mass-market, premium, and commercial electric platforms.
The trend toward platform-based EV architectures is also boosting adoption, as automakers increasingly prefer compact, modular drive units designed for thermal efficiency and simplified manufacturing.
OEM Sales Channel to Capture 80% of Market Revenues in 2025
OEMs are projected to represent 80% of total market revenues in 2025, reinforcing their strategic focus on in-house integration of water-glycol cooled drive systems during vehicle assembly.
This preference is driven by three core advantages:
enhanced compatibility with evolving platform designs,
greater control over performance and safety benchmarks, and
higher production scalability.
OEM integration ensures optimal thermal routing, reduced complexity, and improved long-term reliability-benefits that are particularly critical for high-performance EVs, electric buses, off-highway vehicles, and industrial machinery.
Regional Growth Outlook: Asia-Pacific, North America, and Europe Lead the Charge
The market is expanding worldwide, with several countries demonstrating above-average growth rates:
China: 26.5% CAGR driven by aggressive EV production targets and innovations in cooling technology.
India: 24.5% CAGR fueled by public transport electrification, FAME II incentives, and localization of thermal technologies.
