Koerner has more than 25 years of experience and research, worldwide patents, and customers in 50 countries worldwide.
Heating up the pickling baths yields a considerable reduction of process time and hence a reduction of the number of pickling tanks.
However, in traditional open plants, the benefits that can be derived from this effect are very limited, since the higher bath temperatures result in an increase to the acidic emissions and consequently increased corrosion on cranes, the building and stored material. On top of that, workplace safety (maximum working site concentration) cannot be guaranteed even when employing suction systems on the lateral sides of the tanks.
More than 20 plants set into operation worldwide prove the advantages of this system in practice. Koerner is the only plant supplier that can simulate and predict the flow conditions in each encapsulated plant using its own calculation modules.
The automatic crane and other sensitive plant equipment such as pumps and sensors are protected from the emissions. Thus, it is possible to employ the best available instrumentation, an automatic handling system and to run a fully automated pre-treatment plant. During regular operation, no personnel work inside the pre-treatment plant.
