Eaton has completed the acquisition of cooling specialist Boyd Thermal – for around 9.5 billion US dollars. The well-known UPS and power management provider is thus expanding its portfolio to include solutions for direct liquid cooling.
Boyd was founded in 1928 as an industrial manufacturer and, over the decades, has developed into an experienced supplier of thermal management solutions for the aerospace industry. It is precisely this experience with robust, mission-critical cooling systems that Boyd is now applying to the world of data centres – including its expertise in direct liquid cooling, as required by today’s high-density servers.
Eaton CEO Paulo Ruiz describes the aim as an end-to-end solution “from the power socket to the chip”. AI workloads are driving power density per rack to levels that traditional air cooling can barely cope with. Whereas conventional server racks have long managed with around 10 to 20 kW, GPU-dense AI racks now reach many times that figure – and from this point onwards, there is practically no alternative to liquid cooling. Every kilowatt-hour fed in must also be dissipated.
From our perspective as an Eaton partner, it is clear that those who have previously planned UPS, PDU and rack infrastructure from a single source will, in future, also be able to incorporate cooling into the same ecosystem. This reduces the number of interfaces – a common source of errors in data centres, particularly in the event of a fault.
Even amongst SMEs in the DACH region, power density is rising noticeably as soon as a single AI server or a compact GPU cluster is installed in the existing server room. This raises very specific questions: Is the existing air-conditioning system even sufficient anymore? At what point does it become worthwhile to switch to liquid cooling? And how can power and cooling be jointly protected against outages?
The acquisition of Boyd is more than just a portfolio expansion. It demonstrates the direction in which data centre infrastructure is moving: away from separate silos for power and cooling, towards integrated systems for the AI era. For customers, this means fewer suppliers and greater coordination in the long term. In our shop, you’ll find a wide range of solutions from Eaton, including UPS systems, PDUs, racks, IPM software and licences.
