Founded in 1837 and named after the only physician to sign the U.S. Constitution — Benjamin Rush — Rush University Medical Center (RUMC) is now Chicago’s second-largest hospital, with multi-story buildings that dominate the city’s medical district. However, this prestigious location posed problems when RUMC’s 11-story Professional Building 2 needed to replace two aging centrifugal chillers.

It appeared the only alternative was to move a crane down a crowded street to lower new chillers through the roof. But some simple surgery made it possible for Smardt split-shell chillers with Danfoss Turbocor^® compressors to simply take an elevator up to the penthouse mechanical room, a solution that cut installation costs while boosting energy savings.
