Free Cooling Systems – How They Work

21 January 2024

Free Coolers are designed to lower energy usage and carbon footprint of chilled water systems.

So how do they work? Free Coolers use outdoor air to cool industrial process water. The system circulates process water through heat exchangers exposed to outside air. As the outdoor air absorbs heat from the process water, it cools the water. Temperature controls activate free cooling when outdoor air is sufficiently cool. Cooled process water is then recirculated to industrial processes, reducing the need for mechanical refrigeration. These systems enhance energy efficiency and operational cost savings in industries with significant cooling requirements.
