What happened
Data Center Knowledge reports that SLB will spend about $4.1 billion to acquire Kelvion, including $3.4 billion in cash and approximately $700 million of assumed debt. The deal would expand SLB from modular data-center construction and infrastructure integration into thermal-management equipment, including heat exchangers, dry coolers, hybrid systems and other technologies used to move heat away from increasingly dense AI computing facilities. The transaction is expected to close in the first half of 2027, subject to regulatory approval and other customary conditions.
Data Center Knowledge reports that SLB intends to acquire Kelvion for approximately $4.1 billion. The reported consideration consists of about $3.4 billion in cash and the assumption of roughly $700 million in Kelvion debt. The article says the transaction values Kelvion at about 11 times estimated 2026 adjusted EBITDA before synergies and about 8.5 times after expected synergies. The deal is not yet complete: according to the outlet, closing is expected in the first half of 2027 and depends on regulatory approvals and other customary conditions. These financial terms and the proposed timeline are not independently confirmed in the material provided.
According to Data Center Knowledge, Kelvion would add heat exchangers, heat-rejection equipment and related thermal-management technologies to SLB’s existing capabilities in engineering, modular manufacturing, offsite construction, power integration and digital systems. SLB’s current data-center business has focused comparatively more on prefabricated modular capacity and the integration of third-party equipment. The outlet quotes Dell’Oro Group research director Alex Cordovil as describing the acquisition as a move that could make SLB an original-equipment manufacturer in a rapidly growing part of the thermal-management chain.
The report places the transaction in the context of rising AI rack densities. Data Center Knowledge says SLB reported that modern GPUs are already pushing rack power densities above 100 kilowatts, while some announced chip architectures could approach 1 megawatt. The article explains that direct-to-chip systems, such as cold plates and coolant-distribution units, capture heat at the processor, but that heat must still travel through a cooling loop and ultimately be rejected outside the facility. Kelvion’s equipment would give SLB a larger position in that downstream stage.
Data Center Knowledge reports that SLB plans to incorporate Kelvion’s thermal technologies into its modular infrastructure instead of treating cooling as an add-on after a facility is designed. SLB pointed to its work as a modular design partner for Nvidia AI factories as an example of where the capabilities could be combined. The outlet also reports that Kelvion has operations and customers in Europe, Asia and the Middle East, while SLB has built its data-center business primarily in the United States. SLB says the U.S. will remain the foundation, followed by Europe, Asia and the Middle East.

Why it matters
The reported transaction would give SLB a broader role in the physical infrastructure supporting AI workloads. Data Center Knowledge says SLB expects the combined data-center business to generate more than $2 billion in revenue in 2026 and $4.5 billion to $5 billion in 2028, while Kelvion would expand SLB’s geographic reach and provide technology for water-constrained markets. The deal also illustrates how AI infrastructure investment is moving beyond chips and servers into power, cooling, construction and heat rejection.
The acquisition matters because cooling has become a central constraint on AI infrastructure rather than a secondary facility feature. Higher-density computing produces more heat in a smaller physical footprint, increasing the importance of equipment that can transfer and reject heat reliably. Data Center Knowledge quotes Cordovil as saying the heat-rejection segment is being repriced rapidly, with rack density and pressure over data-center water consumption helping drive interest in dry coolers and hybrid or adiabatic systems. The report does not establish how effective any particular system is in operation.
Water availability adds a public-interest dimension. Data Center Knowledge reports that Kelvion has technologies for waterless cooling applications, potentially giving SLB options in locations where water scarcity or community opposition constrains conventional cooling. That could affect where new AI facilities are built and how their resource use is evaluated. The source does not provide measured water savings, site-level environmental data or evidence that Kelvion systems have reduced opposition at specific facilities, so those potential benefits remain unverified.
The deal could also change how data-center projects are packaged and purchased. Data Center Knowledge reports that SLB sees an opportunity to offer hyperscalers integrated modular infrastructure, cooling and power solutions, potentially including behind-the-meter generation. Its combined data-center business is projected by SLB to exceed $2 billion in revenue in 2026 and reach $4.5 billion to $5 billion in 2028, with $700 million to $800 million of adjusted EBITDA in 2028. Those are company targets reported by the outlet, not independently tested forecasts.
There is also a competitive complication. Kelvion supplies components to other companies in the thermal-management market. Data Center Knowledge reports Cordovil’s warning that SLB would therefore become both a competitor and a supplier to parts of the ecosystem. The commercial outcome will depend on whether customers continue buying from Kelvion, whether SLB preserves those relationships and whether the combined company can provide system-level integration that competitors cannot easily match. The source offers no customer reactions or signed post-acquisition commitments.
What to watch next
The key test is whether SLB can integrate Kelvion’s equipment into complete infrastructure systems and deliver the projected synergies. Data Center Knowledge reports that $120 million in annual EBITDA synergies are expected within three years of closing, but the source does not independently confirm the transaction, its projections, its valuation or the timing. Watch for regulatory clearance, closing, customer commitments, deployment results, water-use impacts and evidence that the combined business can compete while Kelvion continues supplying other thermal-management companies.
First, watch whether the transaction receives regulatory approval and closes on the reported schedule. Until that happens, SLB’s planned expansion remains conditional. The source does not identify specific regulators, jurisdictions under review or any objections. It also does not include an independent financial assessment of the $4.1 billion price, so readers should treat the reported valuation multiples and synergy estimates as management-related deal metrics rather than established outcomes.
Second, watch execution inside the combined business. Data Center Knowledge reports that SLB expects about $120 million in annual EBITDA synergies within three years of closing, including roughly $70 million from cost savings and the remainder from revenue opportunities. The projected savings include supply-chain efficiencies, manufacturing optimization, logistics, service centers and general administration. Evidence of progress would include completed integration, maintained delivery schedules, customer adoption and financial results that distinguish realized savings from forecasts.
Third, watch whether thermal management becomes a durable competitive advantage for SLB. The article quotes Cordovil as saying system design and controls matter more than individual components. That makes integration with modular construction, power systems and digital capabilities important. Relevant unknowns include the performance of the combined systems at very high rack densities, their maintenance requirements, their water and energy consumption, and whether they can be deployed quickly across different climates and grid conditions. Data Center Knowledge does not provide independent tests on these points.
Finally, watch how the acquisition affects the wider AI infrastructure market. SLB says it may combine cooling and modular capabilities with partnerships for power generation, geothermal energy and carbon capture, while Kelvion brings non-data-center exposure to heat pumps, renewables, carbon capture and industrial processing. The source frames cooling as a possible entry point into a broader energy strategy, but it does not establish that these adjacent businesses will result. The most meaningful future evidence will be actual contracts, operating facilities, geographic expansion, customer retention and independently reported environmental performance.
