Steam injector DSH series

pneumatic

The ADCA DSH series of direct steam injection humidifiers are designed to ensure highly efficient and moisture-free steam injection in air ducts and AHU for humidification purposes. These units are completely manufactured from corrosion resistant stainless steel, and are available as plug-and-play packaged solutions or alternatively as individual components to be incorporated into humidification systems. Each humidifier is manufactured as a bespoke solution to meet flow requirements and duct design with single or multiple injection tube design. OPERATION Steam moves in the supply line passing through a strainer to remove solid particles and, if necessary, through a pressure reducing valve to reduce it to humidification pressure (generally around 1 to 2 bar). Steam then passes through an S16TSS centrifugal humidity separator which removes any remaining finer particulate matter and most moisture content. The separator special design dries the steam which is injected and also the steam which feeds the heating chamber keeping heating temperatures stable. As steam leaves the humidity separator and passes through the jacketed injection tubes it is kept at a constant temperature, preventing condensation to be carried over with the steam. Condensate collects on the bottom of the separator and is removed from the system at saturated temperature via an FLT float and thermostatic steam trap. Condensate which forms inside the injection tube heating chamber is removed by means of one or multiple steam traps depending on the case. An ADCATrol globe control valve equipped with a fail-safe electric or pneumatic actuator provides accurate modulation of flow.
