Celebrating 40 years of worry-free solutions

This 11-meter-high door in this video was designed and built for the European Space Agency – ESA in the Netherlands. This year, we are celebrating our 40th anniversary with eight highlights every five weeks until the end of the year.

Bas de Groot can clearly remember this particular project. Bas: “For me, the project for ESA in the video was why I decided to join the company full-time. What stood out to me most was the close collaboration with the ESA team—making the end result a true team effort. My father Hein, who briefly appears in the video, always taught Rik and me the importance of working closely with our customers. Nearly 25 years later, that spirit of collaboration is still at the core of our projects.

This particular project started in 2002, yet we continue to maintain the doors to this day. Recently, we upgraded the large door automation as part of ESA’s preventive maintenance strategy. Our journey in manufacturing shielding began in 1999—a major milestone for us. Having ESA-ESTEC as a reference gave us a warm introduction to the aerospace industry. A few years later, we took on an even bigger project with Thales Alenia Space in Ankara, Turkey.

It’s inspiring to see how long-term relationships and teamwork continue to shape our work. As a second-generation family business, we prioritise stakeholder value over shareholder value. Our commitment to quality, reliability, and collaboration is why we stand by our mission: Worry-Free Chambers.”

What we learned at EMV Stuttgart 2025

We asked two of our technical consultants what they learnt from three days at EMV 2025 in Stuttgart last week. Vincent van de Vrie (photo centre): “Some very interested people were exploring the EMC chamber options we displayed at our booth.

We have a scoop! This week, we will unveil four 3D models of our latest worry-free EMC chamber solutions at the EMV exhibition in Stuttgart (D). In the photo, Marc Le Roy from our sales team is preparing to install the models at booth 417 in Hall C2.

Our services include maintenance and validated testing. We recommend that both are executed by authorized personnel only. Our expert teams can perform preventive maintenance on RF-shielded doors, mode-stirrer systems, and positioning equipment such as turntables. We also offer validation services to see if your EMC test chamber or RF-shielded room still functions within its intended limits and avoiding unexpected down-time or product recalls at the same time.

A shielded room can perform conducted emission and immunity EMC measurements, eliminating harmful external influences, leading to more accurate and consistent test results. Being a Faraday cage, a shielded room will not only improve test results but will also form an excellent aid in protecting information and essential hardware. Comtest can assist governments, the military, financial institutions, and large corporations in protecting what matters most in critical situations. We offer the highest quality, sensitivity, and security before, during and after working with you.
