Opener Technology Made in Germany

How does anyone hit on the idea in the first place of developing automation systems to open and close doors and gates at the touch of a button? The answer is because we know that door openers provide more convenience in everyday life, but we recognise, at the same time, that this is not the whole story. We're aware, for instance, that opener safety is of prime importance, and that we know best how to achieve this. Not just to prevent injury, but also to protect valuable property, day in day out, whatever the weather. And we consider it our mission to achieve safety and user-friendliness time and again by combining innovative technology in new ways, enabling us to come up with one of the safest opener systems in the world.

Strong businesses in partnership


We belong to a strong community. Since 1990, a corporate group has evolved which is unique in its capabilities and international market presence. Marantec in Marienfeld, MFZOVITOR in Legden and Helsinki, as well as Marantec electronics in Zeesen produce and sell their innovative drive and control systems completely independently. Developments evolve in a team of 25 people, consisting of engineers and designers. This provides ideal conditions for ensuring the high quality of every individual part as well as the finished product. In fact, we have received numerous awards in recent years for our technical innovations.

Our openers, controls and peripheral products are also manufactured in our own specialised production facilities: in Marienfeld, Legden, Miesbach and Zeesen in Germany, Helsinki in Finland, Ajka in Hungary, Durban in South Africa and Gurnee in the USA. Ideal networking and infrastructure guarantees products which meet the most stringent quality requirements, speed of delivery and individuality.

Our international customers' special needs and wishes can be accommodated effectively and professionally within the group. The sales organisation also operates on a world-wide basis. With its own sales teams in Europe, North and South America, Asia and Africa, the group is represented almost everywhere. This results in products that are in line with market requirements, for both regional and international applications. An internationally oriented team of specialists offering technical support rounds off our expertise.

The corporate group is, and intends to remain, a family business despite its size. Each and every employee undertakes to uphold its tradition of producing quality products and establishing cooperative customer relations.
