Liquid Distribution Systems

In the mass transfer process an effective liquid distribution system is essential to ensure the performance and efficiency of a packed tower.



The Pall Rings Company supplies an extensive range of liquid distribution systems.

Using our expertise to combine injection moulded sections with traditional fabrication, we can provide strong, dimensionally accurate products.

Our range of liquid distribution systems includes:

Tray type distributor

This consists of a simple flat tray with a series of orifices evenly spaced over its entire area. The liquid is fed directly onto the tray by a feed pipe, which then distributes the liquid evenly over the tower’s packed bed.

Trough type distributor

This consists of a pre-distribution trough or ‘parting-box’ mounted above a number of equally spaced, narrow troughs. Initially, the liquid is fed into the ‘parting-box’, which in turn evenly feeds the troughs below.

Ladder type distributor

This consists of a main central feed pipe or ‘header’, with a number of equally spaced ‘laterals’ projecting perpendicular from each side. Here, the liquid distribution is pressure driven, as liquid is delivered onto the tower’s packed bed through a series of holes in the underside of the lateral pipes. This type of distributor is highly versatile and can be designed to suit a wide variety of applications.

All our distributors can be manufactured in a range of different thermoplastics materials or from stainless steel. They can be used in towers up to 4.5 m in diameter.
