The story of Dana-Seals A/S
Dana-Seals is founded by technical engineer Per Gyllich. In 1992, after a long career as manager in the sealing industry, he and his wife Christina Gyllich started their customised sealing production in North Zealand, Denmark.
Dana-Seals soon became a well known brand in the industry, respected for their ingenious solutions made by loyal and experienced engineers and technicians. Applications to all kinds of conditions are always made to perfection, and promises are always kept.
Then and today, Dana-Seals is known as a company worth working for. Some employees have been at Dana-Seals from the very beginning in 1992 to this day, and customers call Dana-Seals ‘The gentlemen of the industry’.
Our Mission and Vision
Fulfilling customer needs for high quality, customized solutions. We preserve the embedded energy and CO2 by prolonging the service life of machinery, and by that maximize business value.
Transform our industry one sustainable solution at a time. Bring the CSR agenda to the table by telling it like it is, being creative in co-creating solutions and by that securing profit, people, and planet
In 2016 Per and Christina Gyllich transferred the top management to their daughter Louise Gyllich. Today, Per Gyllich is chairman of the board, and CEO Louise Gyllich continues her parent’s vision of a company with uncompromising standards in products, production facilities and long-lasting, trust-based relations to their customers all around the world.
It is Louise Gyllich’s declared vision to continue the work her parents started out in 1992. Today, she combines her parents’ strong focus on growing the core business with an equally strong vision for growing an environmentally sustainable business.
In 2022, Louise Gyllich expanded the production facility. Today, it amounts to more than 2000 m2, making better space for the constantly growing number of employees and customers.
