Bubble Cap Trays

Bubble Cap Tray columns are very often used in petroleum refineries.

Here, the steam flows through the openings in the bottom of the bubble cap. Through the slits in the edge of the bell, the steam bubbles through the liquid, which is prevented by the bells from flowing down to the lower floors. The more complex and therefore more expensive construction of the trays leads to an improved use of the column with fluctuating steam load.

We provide a wide variety of bubble cap shapes and diameters. We also assemble bubble caps specified or supplied by our customers.

Conventional bubble cap trays are well-proven in applications with following conditions:

  • very large loading ranges
  • very low liquid loads
  • very low gas loads
  • continuous liquid hold up
  • low leakage rates
