Milestones

The company Rosenmund AG was founded in 1810 in a small Swiss town called Liestal. With its pioneering work of setting up the first filter/dryer, Rosenmund AG created its reputation of being an international technological leader.

The success of the longtime existence of the company is based on its customer orientation as well as on the consequent focus on product solutions and service offers according to market demands.

In 1999, the company became a subsidiary of the French group of companies De Dietrich Process Systems. Today, Rosenmund® is a global leading brand in the area of mechanical solid/liquid-separation and drying.
