The Copes-Vulcan Multiple Nozzle Spray Desuperheater offers optimum performance and rangeability in a variable spray tube design. The MNSD fills the performance gap between the limited capability of a simple mechanical spray type desuperheater and the virtually unlimited capability of Copes-Vulcan’s Variable Orifice Desuperheater. The MNSD offers high temperature capabilities and up to Class V leakage rating.
