Challenge / question

A lot of energy is needed for the production of fertiliser. As much as 5% of the world's entire gas production is used for the production of ammonia, an important component of fertiliser. This equates to approximately 2% of the world wide energy consumption. This is the reason why many fertiliser factories are located in countries that are rich in oil or gas. Fertiliser is produced in grains which are initially damp and therefore require drying. The best result is obtained by using very dry and warm air in a fluidised bed. This enables us to supply a large amount of important components.

Air-treatment system  

Our solution

A Bronswerk® Air Conditioning Unit sucks in outside air, filters it and cools the air to extremely low temperatures. As a result, humidity rises to 100%; the moisture 'rains' down from the air. Cooling takes place by evaporating ammonia that circulates via natural convection. In order to reduce the moisture even further and remove the last humidity from the air, it has to be preheated. We are experienced in designing and producing Air Conditioning Units and Thermosyphon systems whereby centrifugal fans move the air. We have been manufacturing these fans for nearly a century, using any required material and to any desired shape or form. To completely dry the grains, a large number of air heaters are required. As we also design and produce these in all sizes, shapes and forms, we are able to supply all required components. Furthermore, Bronswerk® is able to offer a suitable and most efficient solution for other types of heat exchangers that are often required as part of the process. We manufacture equipment and components using any material available and according to every certification, worldwide.
