Description
OFFERS HIGH TEMPERATURE CAPABILITIES AND LOW COOLANT CLASS V LEAKAGE RATING
The Multiple Nozzle Spray Desuperheater offers optimum performance and rangeability in a variable spray tube design. The Model MNSD-V 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 (Model VO). And, the MNSD-V offers high temperature capabilities and low class V leakage rating.
