Calmo – Industrial IT Made in Germany
High-quality components such as the industrial mainboards from our German partner Kontron and our in-house development, assembly, and quality control departments at our site in Giengen an der Brenz (Baden-Württemberg) make our embedded industrial PCs, 19" rack solutions, and panel PCs some of the most reliable industrial hardware on the market. With our durable systems, you can achieve secure 24/7 continuous operation throughout the year, even under the toughest conditions such as extreme temperatures, high dust levels, humidity, or contaminated ambient air. Thanks to the combined expertise of our experts in one place, we can offer not only high-quality hardware but also all related services. We support you from project planning to any repairs and individual product development. Quality is our top priority, and we strive to live up to the “Made in Germany” label in the best possible way. Critical components and work processes are always double-checked and carefully documented – and, of course, we are committed to the DIN EN ISO 9001 quality standards.

Calmo S
The Calmo S is our modular and space-saving industrial system for production, automation, and control technology.

The Calmo S is therefore available either as an efficient energy saver or as a powerful powerhouse. Tailored precisely to your requirements.
