Steam Jet Ejector is a equipment used to create vacuum use of high pressure steam is made to create the negative pressure at the suction side of the equipments. The steam and the sucked gases together are discharged through the exhaust port which is slightly at the higher pressure than the discharged pressure. Since steam is compressable and condensable media use of steam ejectors are widely done in the industrial vacuum application.Highly suitable for the corrosive environment needs to be customised by the knowledgeable person to get best results.The proper combination of multiple stages with desired inlet line condensers can produce the best results.
