The chiller, Broad Model BCT16, was provided by the Broad Air Conditioning Company. It is pictured in the following photo.  All components are contained in a single cabinet, with chilled water supply and return, steam supply, condensate return, and a city water supply for cooling water make up; all entering via penetrating pipes.  Chiller components are described in the Flow Diagram section.
