Our Path
OHRMANN continues to embody the outstanding strengths of its founder Cölestin Ohrmann:
Perseverance – Respect – Creativity
From Idea to Company
From Idea to Established Enterprise
The foundation of today’s company was laid in 1986 by Cölestin Ohrmann with his patented founding idea: a machine for assembling internal seals — the OI 10. A process that had previously been considered impossible. The customer response at the first Motek exhibition was so overwhelming that the young company quickly moved from the founder’s kitchen table to the larger premises of an old village school.
The joy of working and learning together forged the still small team during numerous intense commissioning phases and helped cultivate a company mentality that endures to this day. “WE ARE OHRMANN” became a shared identity. We are proud that many employees remain part of the OHRMANN team throughout their entire careers.
Along this extraordinary journey came the gradual expansion to today’s company headquarters in Möhnesee-Wippringsen, as well as the quietly proud market leadership embraced in true Sauerland humility.
The generational transition
After more than 30 years of leadership, founder Cölestin Ohrmann stepped down from management in 2018. Alrun Ohrmann was appointed managing director in 2014, and Gesa Ohrmann has held management responsibilities since 2019.
Since 2012, the owning family has been engaged in a long-term, structured succession process. With foresight and carefully planned stages, they aimed to fulfill both entrepreneurial and social responsibilities. Step by step, a sustainable solution was developed to address how succession in a family business can succeed—technically, structurally, and culturally.
Today, Alrun and Gesa Ohrmann, together with Berthold Klever, lead the company and set the framework for its continued sustainable development.
Our Future
At Ohrmann, we are more aware than ever of our societal responsibility. We actively engage with the question of how we can help shape a sustainable and livable future—and we consistently provide our own reliable answers.
Technically, we support our customers and partners with our expertise in sealing assembly, enabling them as courageous innovators to develop solutions for a sustainable and livable future.
Organizationally, we continuously evolve to master increasingly complex project business. This is the only way we remain experts in contemporary technical and structural solutions. In our Future and Culture Workshop, we provide talents—regardless of hierarchy or department—and ideas room to experiment and grow.
OHRMANN in Numbers
It all started with a single idea: creativity, paired with perseverance and a clear customer focus, has enabled us to grow sustainably as a family-owned company. And to this day, that one idea continues to spark many more results we are proud of.

KlimaSicher
Since 2021, OHRMANN has held the KlimaSicher (ClimateSecure) certificate. The KlimaSicher project was initiated by the districts of Soest, Warendorf, and Siegen-Wittgenstein in cooperation with TU Dortmund and RWTH Aachen University. Its aim is to prepare companies for the challenges of climate change.
Under the guidance of university experts, around 30 companies worked to analyze site-specific risks posed by climate-related hazards such as heavy rainfall, heatwaves, and storms. The goal was to identify local risks and develop tailored measures to increase resilience.
As a responsible company, it is essential for OHRMANN to safeguard both our own infrastructure and our customers’ machines under construction against the effects of climate change. During the project, we focused primarily on the risks associated with heavy rainfall events. As a result, we implemented measures that significantly reduce the potential impact of such events.
By participating in the project and applying these measures, OHRMANN has not only strengthened its own resilience but also sent a clear message: future viability means climate protection and preparedness.
