The closed loop chillers market (Markt für geschlossene Kälteanlagen) is experiencing strong and sustained global growth as industries increasingly prioritize efficient, environmentally friendly cooling technologies. In 2024, the market was valued at USD 4.3 billion. It is expected to rise to USD 4.6 billion in 2025 and more than double to USD 9.9 billion by 2035, registering an impressive CAGR of 7.9%. This upward trend reflects the growing demand for high-performance, energy-efficient cooling systems across data centers, pharmaceuticals, manufacturing, and other sectors requiring precise temperature control. Stricter energy regulations, rapid industrial automation, and the expansion of temperature-sensitive industries are key forces shaping this transformation.

What's Driving Market Growth?

A major factor propelling market expansion is the global emphasis on energy efficiency. Organizations are increasingly adopting closed loop chillers to reduce operational costs while complying with environmental regulations. These systems recycle coolant, minimize water and refrigerant loss, and offer precise temperature control-making them essential for meeting both sustainability goals and carbon-emission standards. In industries such as data centers, advanced manufacturing, and pharmaceuticals, upgrading to closed loop solutions provides long-term reliability, environmental benefits, and measurable cost savings.

Automation is another key accelerator. Modern production lines, robotics, and smart factories rely on high-precision machinery that generates continuous heat. Closed loop chillers have become crucial to maintaining optimal equipment performance in these automated environments. The integration of Industry 4.0 technologies-AI, IoT-enabled sensors, and advanced robotics-has further increased the need for stable and uninterrupted cooling, reducing downtime and extending equipment lifespan.

Environmental regulations also play a major role. Governments around the world are enforcing stricter standards for energy use, emissions, and water conservation. As outdated, high-emission open-loop systems are phased out, closed loop chillers are becoming the preferred choice. Their ability to minimize environmental impact aligns with corporate ESG commitments and supports companies aiming to stay competitive while meeting sustainability targets.

Recent Market Developments

Manufacturers are responding to rising demand with innovative, high-efficiency solutions.

• Daikin introduced a glycol-free zoned cooling system in October 2024 under its TZ D air-cooled free-cooling chiller series. Eliminating the need for glycol enhances operational efficiency and serviceability across installations ranging from 180 kW to 2,150 kW-ideal for facilities managing large heat loads.

• Carrier India launched the 30RB Air-Cooled Modular Scroll Chiller in May 2024, engineered specifically for local industrial needs. Designed for reliability and efficient performance in diverse applications, this model supports India's push toward strengthening domestic manufacturing capabilities.
