ECM Greentech is the ECM Group subsidiary dedicated to renewable energies. Historically specialized in silicon ingot growth equipment, ECM Greentech is now able to provide turnkey solutions for solar panels production. It covers the entire value chain, from crystallization to cells manufacturing. The integration of SEMCO Smartech has enabled ECM Greentech to enhance its equipment portfolio by specializing in the production of TOPCon solar cells.

ECM Greentech has extensive expertise in thermal processes for renewable energies. This has led the Group to take part in high-potential projects, such as the development of green hydrogen production (in collaboration with GENVIA) or the CARBON project for the creation of a solar gigafactory at Fos-sur-Mer.

ECM Technologies’ success is directly linked to the development of vacuum technology in the automotive industry. Our patented low-pressure carburizing process is now the most widely used among automative manufacturers and their subcontractors. The development of the electric car and the need for high torque have enabled ECM’s Technologies to become one of the leading industrial partners in the market, from two-wheelers to trucks.

The modular installations supplied by ECM Technologies are designed for the world’s largest manufacturers in terms of volume, as well as for small and medium-sized companie. Thus making ECM solutions relevant and suitable for any industrial company wishing to combine performance and cost control, all in a sustainable approach and support to  industry decarbonization .
