Column Internals

Column Internals

A strict quality management system guarantees the product quality and delivery time of the project.

Technology Introduction Of Column Internals

The tray design and manufacture technology by DODGEN has realized the breakthrough of low pressure drop, high tray efficiency, anti-blocking, high vapor-liquid/liquid-vapor ratio and high operating flexibility. As one of the column internals manufacturers, we provide our customers with reliable hydraulic design, cost-effective tray selection and rich tray types.

Characteristics of Column Internals


Liquid distributors with liquid load from 0.01m3/m2h to more than 200m3 / m2h;


High operating turndown and suitable for fouling systems including suspension, emulsion and dust. Both gas and liquid can be distributed well;


Different types of gas distributors and flash feed systems according to different gas velocities;


Different types of collectors according to different applications, such as vane collectors, chimney tray collectors, collectors/redistributors, etc;


Different types of support grids ( for structured packing & random packing);


Three-in-one distributors(support grid + collector + distributor);


DODGEN has a 16 * 16m distributor test platform.
