A large hospital in Galveston, Texas, had lost one of its chiller motors. In the heat of a Texan summer, where daily temperatures push above the 90°F (32°C) mark, the remaining chiller was struggling to keep up with demand. The hospital faced the unpleasant prospect of having to shut down within 48 hours. But before it did, they called us to see if there was something we could do. We were confident we could provide rapid ready-to-go cooling in that time.
