Atherm moves to its new, larger, site

22 Oct, 2026

Atherm is happy to announce a major new milestone has been reached, as the company has moved its headquarters to a new, larger, industrial site.

Owned by our shareholders –the Seres group and the Japanese group Sanken– the made-to-measure building offers more than double the floorspace of the existing installation, creating the conditions to boost the company’s France-based production. The new factory is based at Le Versoud, near Grenoble.

The R&D design office, the quality assurance department, the administrative and logistics services, and the manufacturing workshops are moving from a 1500 m 2 facility to a space measuring 4000 m 2.
“We decided to acquire the site and build on it to support our increasing France-based production and to prepare for the future”, explain the shareholders and management.

More than double the floorspace
The new building should allow the company to better meet its clients’ needs, now and into the future. With more than double the manufacturing floorspace, Atherm will be able to absorb activity peaks, which had become a real challenge in the previous building.
The R&D design office conceptualises custom-made thermal solutions and now produces prototypes from a larger test production area.
The quality assurance department now has a dedicated space equipped with test benches to study finished products. This improved set-up facilitates the work of the teams and the maintenance of our
ISO 9001 certification, originally obtained in the early 2000s, and regularly renewed.
Finally, the logistics service, in contact with clients the world over, is moving to an even more efficient configuration, with benefits expected in production and for clients.

A modern, made-to-measure acquisition
The building, purchased by the shareholders –the Seres group and the Japanese group Sanken– wasconstructed according to specifications based on Atherm’s needs. Located in Le Versoud, near Grenoble (southeast France), it applies the latest technology, for both electricity and temperature control.

Solar panels cover more than 50% of the roof, and the insulation meets the requirements of the most
recent standards, making Atherm’s new HQ much less energy-hungry and more pleasant to work in.
The electricity produced on-site is used to power some of the machines.
The installation started in March and was finalised over the summer, with no interruption to the company’s activity.
