This is the third and final installment in the series on using makeup air unit (MAU) cooling coils as dry coolers.

Using chilled-water cooling coils within makeup air units (MAUs) as dry coolers offers enhanced operational stability even in lower ambient temperatures. Explore real-world case studies, where smart sequence modifications optimized performance.

This is the first of three articles on the application of MAU cooling coils as dry coolers.
