The Daniel K. Inouye Solar Telescope (DKIST) under construction on the Haleakalā volcano summit in Maui, HI, will provide the sharpest views ever taken of the solar surface, but requires precise thermal control of its dome exterior, which will be provided by Griswold™ 811 Series Centrifugal Pumps.

While innovative, adaptive optics will provide the sharpest views ever taken of the solar surface, these images could be distorted if the thermal system in the telescope is not managed correctly. Therefore, obtaining precise optical performance will require close control of the telescope’s thermal environment.

Griswold™ 811 Series centrifugal pumps meet specs and timetable for critical thermal-control functions.
