Kleve, Germany. The next step in a successful collaboration: the Wilo Group has acquired a majority stake in systems engineering company PreFab, thereby strengthening its strategic position in the digital and AI age.

The jointly produced container solutions are used, among other applications, in building services equipment for data centres and in decentralised modular energy supply systems for innovative industrial and commercial projects.


“Wilo’s Group Strategy reflects our firm conviction that a sustainable future can only succeed if we systematically combine water technology and artificial intelligence. That is why we decided to acquire a majority stake in PreFab,” explains Oliver Hermes, President & Global CEO of the Wilo Group. This strategic step is contributing to growth not only in the data centre sector. “We are also consistently expanding our solution expertise in growth fields such as local and district heating. Together, we are unlocking new market potential,” says the Wilo CEO.


Jan Vierboom, Managing Partner of the Berns Group, adds: “PreFab’s further growth can only be achieved together with a strong partner like Wilo. At the same time, PreFab remains part of our story: we will stay connected as shareholders, as the site’s landlord and as close partners.” The Berns Group founded PreFab, a company specialising in the industrial prefabrication of technical building equipment modules, in 2021. Wilo’s acquisition of the majority stake builds on a successful collaboration in the field of manifold manufacturing.
