Our success is the combined result of experience, expertise and innovation
We are convinced that a company that focuses on its strengths will always be the one that is successful. Our Trigonal® machines are our strength! They employ a simple operating principle: wet size reduction and other kinds of processing of several materials, of which at least one is in a liquid state. And this is done at the highest technical level. That is why Siefer stands for long-lasting products that do their job reliably – in countless cases for decades.
