Special designed impregnation machine for factory in Brazil.


Haldor Topsøe A/S is well-known globally for being one of the leading companies in the field of heterogeneous catalysis, including catalytic elements (monoliths), which can reduce harmful toxins in i.e. internal combustion engines. Haldor Topsøe A / S has chosen to expand their global market share and move into the South American continent and build a factory in southern Brazil in the region Santa Catarina. The purpose of the factory in Brazil is to finalize untreated monoliths in an impregnation and calcination process, and prepare them for delivery.


In cooperation with Haldor Topsøe A/S DIS’ task was to develop a simple production line for the physical handling of the product and to prepare all drawings and the electrical documentation. Furthermore, DIS programmed the user interface of the impregnation fluid’s mixing system from Topsøe’s P&I diagrams and calculation input. The impregnation machine for Brazil had other specifications than the machine for the Chinese market and among other it had to be able to handle three monoliths at a time where the machine in China only had to handle one at a time.


In addition, the machine had to be able to place the monoliths with a maximum deviance of 1 mm. A requirement that placed very high demands on the mechanical design as well as the PLC software. This resulted in a material handling function test in the workshop at DIS in Aarhus, and ended up with a system that was able to handle items up to 530 mm within the necessary precision.


- Once again we chose to cooperate with DIS, as they have previously delivered highly professional work in the development of specialty machines for Haldor Topsøe A/S, and we know what to expect from DIS. DIS chose the right consultants for the task in Brazil and contributed with a positive and flexible attitude and delivered on time and performed at a high level, says Anders Lund Aaker, Project Manager of Haldor Topsøe A/S.
