Product Description Product DescriptionSaiptech's Side to Side Baffle and Disc and Donut Trays For systems where extremely high capacity, fouling and pressure drop are major concerns, side to side baffle and disc and donut trays may be a suitable choice. For both of these tray types, liquid and vapor contacting is accomplished by vapor passing through a curtain of liquid falling from one tray to the next tray below. The tray decks are flat or inclined plates that block 40-60 percent of the cross sectional tower area. In addition to the sloped configuration for the tray decks, other design variations may include inlet or outlet weirs, uniform or partial perforated design. Typical side to side trays are depicted at right. Typical disc and donut trays are depicted below.
