Connections to Universities and Associations

We keep learning and never stop: This is why we are working in close cooperation with universities, colleges and associations in our industry. That way, we can expand our know-how around bulk material handling. And also for the BULKup we put a lot of effort into continuous research and optimisation – for a high-quality product and happy customers.
