The vertical vessel (Tower, Column) is equipped with installations inside that enable an intensive contact between the scrubbing liquid and the exhaust gas to be cooled. The choice of installations depends on the composition of the exhaust gas.
The naming of the cooling type depends on the kind of internal columns.
- Packed-bed evaporation cooler
- Packed evaporation cooler
- Tray evaporation cooler
- Spray evaporation cooler
Key features:
- CFD simulation for optimized gas distribution and nozzle arrangement
- No dust agglomeration on distribution plates thanks to rapping devices
- low maintenance and low maintenance costs
- Compact design
- Cleaning function available only after a specific deadtime
Working Principle
Working Principle of Packed Column Cooler
The gas and cooling liquid are inserted into the counterflow.
The exhaust gas to be cooled enters at the lower end of the column and is led to the upper end.
At the top, the cooling liquid is distributed equally over the whole tube cross section and flows down again over the column installations where it is collected in a container.

The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.
How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
