Abstract: The present system uses a heat exchanger to heat or cool a fluid for circulation through a heat exchange garment. A main feed line, flow control valve, and main return line provide continuous circulation of a fluid. Multiple branch feed lines operably connect multiple heat exchange garments to the main feed line, and multiple branch return lines operably connect those garments to the main return line. The main feed line and main return line are suspended overhead, and branch feed and return lines are affixed to elevated portions of support members to keep tubes and lines up and out of the way. The support member may be an infinitely rotatable support member allowing tangle free rotation of greater than 360°. Individual flow control valves may be disposed at each work site. Also, separate sources of hot and cold fluids may be provided at each work site.
