About Neptunus

For over 85 years, Neptunus has been building tents and temporary accommodations for prestigious sports events, fairs and festivals, as well as temporary buildings for supermarkets, sports halls and distribution centres, among others. In fact, wherever temporary space is needed.

A bit of history

Neptunus was founded in 1937. During a walk on the beach along the Dutch coast, Anton Eilers found a sea chest that had washed ashore. Once home, he opened this crate and found it contained a tent. He erected the tent and invited the whole neighbourhood to a big party. A resounding success, he decided to rent out the tent from now on. He set up a company and named it after the trident on the lid of the washed-up box. This was the beginning of Neptunus.


The Neptunus family

Since then, Neptunus has grown into an international family business. The third generation of the Eilers family is at the helm and the fourth generation is slowly pouring in. With headquarters in Kessel and foreign branches in Germany, Belgium, England, France, Poland, and Austria, Neptunus employs over 300 people.

Directie Neptunus


Neptunus has all relevant disciplines in-house. With the Research and Development department as the brains of the organisation, Neptunus is characterised by innovation. Neptunus was the first in the world to develop and build a tent with two and even three floors. Even in today’s market, our temporary buildings, the Evolution and Flexolution, are still among the most innovative structures on the market.
