STRONGER TOGETHER

Part of Orange Climate

In 2014, Autarkis received a new impulse with the establishment of Orange Climate, bringing together knowledge, innovation and practical experience. In 2023, the companies underwent a rebranding to create one recognisable identity. In 2025, the companies decided to continue independently. However, collaboration remains in place, allowing knowledge and expertise to continue strengthening each other. Orange Climate website

Production facility in Ootmarsum

The power behind our PCM technology

Ootmarsum is home to the production facility where Autarkis’ PCM solutions are manufactured. Here, Phase Change Materials (PCM) are processed into high-quality products for applications in the built environment, such as climate ceilings, climate floors, thermal storage tanks and air handling units.

The facility combines specialist knowledge of PCM technology with a modern production process, enabling both standard products and customised solutions to be realised efficiently. By keeping production in-house, we can closely monitor quality, lead times and product development. From Ootmarsum, an experienced team works every day on the continued development and production of innovative PCM solutions that contribute to energy-efficient and comfortable buildings. Our products
