Process cooling engineers are constantly striving for more efficient systems — and for good reason. Most process cooling systems consume approximately 60 percent of a building’s energy, and seemingly modest gains in efficiency can have significant, measurable effects.

System designers typically have focused on optimizing elements of the process cooling systems themselves. For example, engineers have improved fan blades for cooling towers, designed improved tubes for chillers and many other innovations. These optimizations have caused notable and important gains in efficiency.
