This chamber, which we built for testing Envirotainer’s containers to protect medicines, is larger than you might think. “The team from Envirotainer, a global leader in temperature-controlled logistics for biopharmaceuticals, approached us in 2022 to build a new ferrite chamber to test these containers for shipping by air, which requires DO-160 compliance,” explains Uliana Trucchi, our Technical Consultant for this project.

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.

Why and when did we start developing and producing absorbers for our chambers? This year marks our 40th anniversary, and every five weeks, we share a bit of Comtest’s history.
It was 2009, and our founder, Hein de Groot, was guiding the company in a new direction. His eldest son, Bas de Groot, was committed to taking over the firm, and Hein, who was already 60 years old at the time, decided to undertake one final venture for Comtest Engineering: developing a new type of polystyrene absorber to make the company more independent in the future. Hein is the man second from the right in the first photo with the Delta team (now: FORCE Technology).
Bas de Groot (fourth from the left in the first photo) remains impressed by his father’s vision and energy during his final days as managing director.
Bas: “His mission to constantly prepare the company for the long term is typical of family-owned businesses. And we still cherish that drive and culture today. It was an incredible moment when our first absorbers were unveiled to the public at EMC 2012 in Rome, as shown in the second photo, featuring a forever young Uliana Trucchi. We created a new company for the development and production of the absorbers called Dutch Microwave Absorber Solutions, led by my brother Rik de Groot.”
Are there any upcoming product launches?
Rik de Groot (in the third photo with the new Mobile Absorber Wall): “Yes, we are working hard on developing a new wedge absorber. I cannot go into details yet, but we are planning to launch this new product in the first quarter of next year. So keep following the Comtest news on LinkedIn or the website to stay up to date.”
Bas de Groot: “We are seeking early adopters for our new dust-free, rigid EPS wedge absorber and are offering an exclusive early-bird discount. Please let us know in the comments if you’re interested or send a direct message to me.”
We thank the team at FORCE Technology for their loyalty over more than 15 years and for trusting us to be the launch customer for these new absorbers. Thank you, Per Thåstrup Jensen, Inge Lise Bank Melgaard and Martin Randrup Villadsen.
