The majority of tanks sold by Haase consist of two walls, enabling the use of leakage detection systems and providing an extra safeguard against leakage into the soil or the environment. In many cases the tanks are assembled on-site from composite parts and individual components such as bottom covers, top covers and valves. This allows entry of sizeable tanks into the building through relatively small doors and windows. Often there is no need for special installation permits, and installation can be as fast as two days.
The Reichstag Building hosts the German national parliament. For the new backup power supply system located in the cellar of the building, it was required to install a 10 m³ storage tank for AdBlue chemicals. These are used to neutralise the nitrous oxides in the exhaust gases produced by the large diesel generators.
The Reichstag Building dates back to 1894. In those days, it was not foreseen that such large tanks would need to be installed.
“We realised that access to the cellars was very limited and only small components could enter through existing doors and windows,” explains Thomas Falkenbach, General Manager of Haase. “Fortunately, we were able to bring in all individual components one by one, and assembled them on the spot into a solid and complete tank system. I am sure this system will perform in a reliable way and demonstrate many years of continued operation.”
The Haase tanks are manufactured with Atlac 430 and Atlac 580 resins from Aliancys, supplied through distributor Büfa. The resins are said to provide excellent resistance to a wide variety of chemicals and easy to process into composite parts. Haase uses several manufacturing processes, including hand lay-up, spray-up, and continuous lamination with UV cure.
“We like to use resins with high quality consistency, so we can well predict the performance of the components we make,” says Heike Pohl, Quality and R&D Manager at Haase. “For that reason we have been using Atlac resins already for a long time, as we know they will perform. We also very much appreciate the support we get from Aliancys and Büfa, helping us with chemical resistance advice and material recommendations. This allows making the right tank for a specific application, and so we can best service our customers.”
