TD Downcomer

TD truncated downcomer could increase the liquid flow path length and bubbling area, so that the tray capacity is enhanced much.

1. Bubbling area is increased by 10%~30%, with more advantages when the downcomers are larger.

2. BPV valves are applied on the tray below downcomer, which completely eliminates tray leakage;

3. Applicable to all types of trays;

4. Easy to design, install and standardize.
