Reference installation

What an installation in service demonstrates. And what it does not promise.

A reference installation shows that the technology works at industrial scale, integrated into a real process and operated day to day.

It grounds technical discussions: what was built, how it is integrated, how it is operated.

It does not guarantee the outcome at another site. Each project is assessed on its own data.
