60+ years of market leader in the recreation industry

In 1959, Gré and Cees Seijsener built a touring caravan in their small shed in the Luiksestraat in Zaandam. This pleased them so much that in 1963 they decided to set up an electrical company called Seijsener Elektrotechniek. The first orders quickly came in and, together with Camping de Egmonden, they developed a shower coin machine. This was the start of rapid growth.

In 1968, the company burst at the seams of Gré and Cees's home and moved to a larger 300 m² building. Four years later, this building was also too small, and the company moved to a 2000 m² building on the Achtersluispolder. Here, Seijsener transformed from a family business into an established name in the Netherlands.

Not only did the name of Seijsener Elektrotechniek change to Seijsener Rekreatietechniek BV, but the cooperation with recreation companies also became closer. Seijsener not only offers advice, but also the production, installation and management of recreational technology. It became clear that entrepreneurs enjoy having a partner who assists them in all aspects of entrepreneurship in the recreation industry.

Seijsener is now active throughout Europe with offices in Belgium, Denmark, France and Germany. Our knowledge is very broad and we have specialists in every field. Nevertheless, we remain true to Gré and Cees Seijsener's vision: “Seijsener - Clever thought, well executed.”

Our brand values -
The basis of our success

Our brand values are Seijsener's unique arguments. They are the essence of what makes Seijsener unique and what motivates us.

Leading edge

When it comes to technology for campsites, ports and electric charging, we are leading the way. We're not just setting the bar high; we're setting the bar.

Proud

We are sober types, but we are also proud. To the innovative things that Seijsener develops itself, and to our well-known and valued name among customers.

Freedom

We feel free to take the initiative ourselves. That's why we're open, direct and don't mince words. That might make us a bit outspoken. But always: honest and clear.

Personal

The people at Seijsener determine our success. They are the poster child to the outside world. It is therefore inevitable that personal contact is very important. We help each other move forward — colleagues, customers and partners.

Development

We want to move forward; smarter, better, more sustainable. Seijsener is always evolving. We are good at that, because we see more and more opportunities. Fortunately, we have all the knowledge, expertise and technology to carry this out.
