Variable Annulus Desuperheater – VAD

The VAD is a cost effective, line size desuperheater. Produced from stock materials it is readily available to satisfy general desuperheating and gas cooling applications. Essentially a dynamically contoured, stainless steel spray head concentrically located within a short section of pipe (body). The pipe acts as the desuperheater’s outer body and pressure boundary. It fits into the main vapor line via either line size flanged or butt weld end connections for easy installation.
