Nexus Controls… we’ve been here all along

Nexus Controls was rebranded as part of Digital Solutions at Baker Hughes back in October 2019. However, the Nexus Controls story began long before that. Our business today exists as the collective experience and history of multiple companies whose lineage spans 150 years.


Beginning with The Woodward Governor Company and encompassing longstanding relationships and synergy with General Electric and Baker Hughes, the entire Nexus Controls story demonstrates our intense focus on innovation, customer relationships, and measurable outcomes – the three pillars of our historical success.  

Our unique history is what made us a leader in the energy technology, industrial controls, DCS, safety systems, and cybersecurity markets. It is important to us because it is who we are.

And although you might not know us by name… we’ve been here all along.
