DSM SeriesSM De-Super Heater is a cooling device that injects refrigerated water into superheated steam to reduce its temperature.
The SM De-superheater consists of a coolant spray nozzle and static mixer which takes care of agitation and evaporation.
The forced stirring effect ensures an accurate control of the steam temperature.
