Plasma physics research aided by axial flow valve

The cooling of the coils and electrical and electronic equipment at the Princeton Plasma Physics Laboratory is accomplished by a closed system circulating up to 2800 gpm of deionized water at 140 psi, chilled to 110C. The pulsed heat load, 45 MBtu maximum, is removed by a cascaded pair of 1825 ton centrifugal chillers and is carried by the process water system to a 75 MBtu cooling tower. A description of this system is given
