Fisher™ DVI Steam Conditioning Desuperheater

The Fisher DVI desuperheater injects spraywater in the outlet of the venturi section, assuring excellent mixing and rapid atomization. The DVI desuperheater is easily installed between flanges in DN25 through DN600 (NPS 1 through 24) steam lines. There are no moving parts, and the water injection pattern provides rapid and thorough cooling. It is intended for applications with moderate load changes and low velocity steam.
