MNSD Multiple Nozzle Spray Desuperheater

Description

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-Vulcans Variable Orifice Desuperheater. The MNSD offers high temperature capabilities and up to Class V leakage rating.
