Across industries, operators are adopting cooling tower direct drive (CTDD) motor technology. In particular, permanent magnet (PM) direct drive motors are delivering measurable improvements in efficiency, cleanliness and maintenance reduction. The change is more than a component swap; it represents a new approach to cooling tower design that reduces operating costs, supports environmental goals and improves reliability.
“ASHRAE Guideline 36 is basically a high-performance sequence of operations for large buildings, such as large manufacturing plants, hospitals and hotels. The core concept is to have our load dictate what we do, not the other way around.” — Keith Earhart.

The Cordia Minneapolis district energy system has evolved since it first went online in 1972 to include one main plant and nine satellite plants providing heating and cooling to over 100 buildings. Those buildings are some of the biggest in the state, including the homes of three professional sports teams (U.S. Bank Stadium, Target Field and Target Center), the Minneapolis Convention Center, the Minnesota Star Tribune printing plant and Augsburg University. The steam and hot water system includes 39,000 feet of piping. The chilled water system includes 24,900 feet of piping and has a cooling capacity of 37,550 tons.
