The global closed loop chillers market was valued at USD 4.3 billion in 2024.  The market is expected to reach USD 9.9 billion by 2035 from USD 4.6 billion in 2025, at a CAGR of 7.9%.

The closed loop chillers market has been quietly growing over the past few years. In 2024, it was estimated to be worth around USD 4.3 billion. By 2035, it is expected to nearly double to about USD 9.9 billion. That is a steady growth rate of roughly 7.9% per year. This growth is not random industries like pharmaceuticals, manufacturing, and data centers all need reliable cooling, and there is a clear trend toward systems that save energy and cut costs at the same time. Companies are realizing that cooling is not just a utility; it is a critical part of running their operations efficiently.

Why Companies Are Choosing Closed Loop Systems

Energy efficiency seems to be the main reason these systems are becoming popular. Closed loop chillers use less power than older systems but can maintain a very steady temperature. For pharmaceutical companies, even minor fluctuations can affect product quality. Data centers, on the other hand, cannot afford hardware to overheat, so reliability is a must. On top of that, governments are cracking down on energy usage and emissions, which nudges companies toward replacing old systems with something more modern. The result is a market where companies want systems that save money, reduce risk, and meet environmental expectations.

The Influence of Automation

Automation is changing the game too. Factories are now running robotic assembly lines, AI-managed processes, and precision equipment, all of which generate a lot of heat. Keeping these systems cool is no longer optional. Closed loop chillers can maintain consistent conditions even under heavy workloads. When paired with monitoring technology, operators can predict issues before they happen, avoiding costly downtime. It is clear that as factories become “smarter,” cooling technology has to keep up.

Environmental Pressures Are Real

Regulations around water use, emissions, and energy efficiency are tighter than ever. Closed loop chillers help companies meet these standards because they are designed to minimize water waste and prevent refrigerant leaks. For many companies, adopting these chillers is not just about compliance it is also a part of sustainability goals. It appears that facilities that invest in modern cooling systems can reduce costs while also appearing more responsible environmentally.

Technology Is Shaping the Market

Modern chillers are not just big metal boxes anymore. Many systems now include digital monitoring and predictive maintenance. This means operators can see how the equipment is performing in real-time and fix problems before they cause downtime. Remote access, predictive alerts, and analytics make managing large systems much easier. These features also save money and energy, which makes them appealing to companies trying to cut operating costs.

Regional Differences

North America is leading the way, mainly because of its well-established industrial base. The growth of cloud computing and AI has led to more data centers, which need advanced cooling systems. Government incentives and efficiency standards also encourage companies to upgrade their equipment. In pharmaceuticals, controlled environments are essential, which drives consistent demand for reliable chillers. Japan is seeing steady growth as well. Its focus on high-tech manufacturing and precision industries supports the need for reliable cooling. Government policies promoting energy efficiency and sustainability also help. In addition, pharmaceutical and biotech companies continue to demand systems that maintain precise temperatures. Many facilities have added digital monitoring and AI-based maintenance to improve efficiency and reduce costs.

What Companies Are Using

Packaged chillers are popular because they are compact and relatively easy to install. They are often paired with monitoring technology, which helps operators identify problems before they happen. In terms of industry use, pharmaceuticals make up a large portion of demand. Strict regulations around temperature, humidity, and contamination make these chillers almost a necessity. Other industries like food processing and electronics manufacturing are also adopting closed loop systems because they need precise and reliable cooling.

Looking Forward

The market looks set to keep growing. Energy efficiency, automation, regulations, and technology adoption will all continue to drive demand. Companies that prioritize sustainability, reliability, and cost savings are likely to continue investing in closed loop chillers. At the end of the day, these systems are more than just cooling they are a way to maintain operational control, reduce risk, and support long-term efficiency.
