Bubble Cap Tray

Arabo Filters BubbleCap Trays are designed for leak-tight, efficient separation, even at low vapor loads. Thanks to their versatile and self-sealing design, they outperform other tray types in demanding conditions where stability, fouling resistance, and wide turndown are critical.
Arabo’s bubble-cap trays use vertical risers with slotted caps to ensure strong vapor–liquid contact and effective mass transfer. With turndown ratios of 4:1 to 6:1, they perform reliably even at low vapor loads. The design minimizes weeping and maintains stable liquid holdup for consistent operation.
Each tray typically includes 30–80 caps, with diameters from 50 mm to 125 mm, depending on column specs. Designed for towers from 600 mm to 6000 mm, they’re constructed from 304/316L stainless steel or high alloys for corrosive environments. Operating at vapor velocities up to 2.5 m/s, they are commonly spaced 450–600 mm apart for optimal efficiency.
