Copes-Vulcan Multiple Nozzle Spray Desuperheater


The Multiple Nozzle Spray Desuperheater (MNSD) from Copes-Vulcan, a division of SPX Flow, provides accurate steam temperature control via water atomization. Multiple cooled nozzles inject water into the steam flow to absorb heat for precise temperature regulation.

With high turndown and no need for a separate cooling water valve, the MNSD efficiently controls steam conditions in power plants, refineries, and other industrial processes. Its variable nozzle design suits intermediate-capacity applications.
