The DA-90SE is a fixed-nozzle desuperheater from the IMI CCI product range, designed for steam systems where flow velocity is low or fluctuating. It uses auxiliary steam to finely atomise the injected cooling water, delivering effective temperature control with minimal thermal stress. The unit performs reliably even in highly variable load conditions, maintaining temperatures just 5–8°C above saturation. With a compact, stud-welded design and high wear resistance, it installs easily into pipelines of DN150 or larger. The DA-90SE is widely used in power plants and process industries to protect downstream equipment and enhance heat transfer performance.
