In March 2026, RGS Development announced that it will continue to operate under a new name: Thermagy. The rebranding marks a milestone in the
company’s evolution. It reflects the continuous expansion of its technological capabilities, and the growing success of its thermoelectric devices.
Thermagy remains strategically focused on innovative applications associated with conversion of thermal to electrical energy, energy storage and thermal management.
After a period of research and development, Thermagy has evolved into a high-tech scale-up. The company is capable of delivering advanced solutions for thermoelectric energy conversion in extreme conditions. Its highly qualified team develops and provides advanced components for various aerospace and defence applications, as well as thermally critical assemblies for combined heat and power systems. The new name captures the core of the company’s focus and better reflects its scope and vision toward the future.
Thermagy stands for the ability to imagine and realize thermal-electrical energy conversion solutions. “We are always pushing boundaries in energy conversion technology and streamlining energy solutions for extreme conditions,” says Maarten den Heijer, CEO.
