Baffle, disc-and-donut and showerdeck trays

These trays are typically applied in severely fouling services.

They are configured in a way that the liquid flows downwards through the column, splashing from one baffle to the next lower one. Ascending vapour contacts the liquid by passing through the liquid curtains. These trays are used in washing sections where fouling resistance has priority over high efficiency.
