  • SKF’s MBx Bearing Aims at Data Center Chiller Lead Times, Not Just 30–40% Savings

    SKF’s MBx Bearing Aims at Data Center Chiller Lead Times, Not Just 30–40% Savings

    TL;DR · 30-second read

    The Short Version

    Data centers, the buildings full of computers behind every app and website, get very hot. Giant cooling machines called chillers keep them running.

    Swedish manufacturer SKF makes parts that let the spinning heart of those machines float on magnets, with no oil and no rubbing. It says this design can cut energy use by up to 30 to 40 percent compared with older designs.

    The newer twist: SKF redesigned the part so factories can build it faster, because data center demand for these machines is growing.

    SKF, the Gothenburg, Sweden-based bearing maker, announced on October 7, 2026 that it will launch its new MBx active magnetic bearing series for high-speed chillers at Chillventa 2026, the refrigeration and heat-pump trade fair in Nuremberg, Germany, running October 13–15. SKF says the MBx is designed to optimize cost while maintaining performance, using automatic winding and a modular design that enables semi-automated production, faster assembly, shorter lead times and more production capacity for its high-speed motors to meet growing demand from the data center chiller market.

    SKF will also show its new CeraDrive hybrid ceramic bearings and a new Extreme super-precision bearing platform rated for speeds up to 120,000 rpm. The company says its broader magnetic-bearing drive offering delivers energy efficiency improvements of up to 30–40% compared with conventional technologies.

    Executive Summary

    SKF is pitching three bearing technologies at compressor and chiller manufacturers, the companies that build the large cooling machines used in data centers and heat pumps. The headline product is MBx, a new active magnetic bearing, meaning a system that holds a spinning shaft in place with controlled magnetic fields so it never touches a surface and needs no lubricating oil.

    What stands out is how SKF describes the MBx’s purpose. Its stated innovations are manufacturing ones: automatic winding, a modular design, semi-automated production and faster assembly, aimed explicitly at reducing lead times and expanding capacity for the data center chiller market. The efficiency figure in the release, up to 30–40%, describes SKF’s integrated oil-free drive offering against unspecified conventional technologies rather than a new gain from MBx itself.

    For data center operators and the chiller makers that supply them, that framing matters. It suggests SKF sees the near-term opportunity in its customers’ ability to get enough oil-free drivetrains, quickly and at the right cost, not only in squeezing out further efficiency.

    The New Part Is a Manufacturing Story

    Read closely, the MBx announcement is less about a performance breakthrough than about production. SKF says the bearing is “designed to optimize cost while maintaining performance” and lists its innovations as automatic winding (machine-wound electromagnet coils rather than more labour-intensive methods) and a modular design that enables semi-automated production and faster assembly. The company states the purpose directly: to help reduce lead times and expand production capacity of SKF high-speed motors “to meet growing demand from the data center chiller market.”

    That is a meaningful signal about where SKF thinks friction lies in this market, in the commercial sense rather than the mechanical one. A centrifugal chiller, the type of large cooling machine common in big data center plants, is built around its compressor, and an oil-free compressor is built around its motor and bearing system. If that drivetrain is slow to source or expensive to produce, it constrains how many oil-free chillers a manufacturer can ship. And a data center cannot bring capacity online without the cooling plant to support it. SKF has not said its lead times are currently a problem for customers, but it has chosen to make shortening them the headline benefit of its new product.

    The people most directly affected are chiller and compressor manufacturers deciding whose magnetic-bearing systems to design around. Downstream, data center developers and their engineering contractors care about two outcomes: whether oil-free chillers become cheaper relative to conventional units, and whether delivery schedules for cooling equipment get shorter. SKF’s release claims progress on the inputs to both, without yet quantifying either.

    Why Oil-Free Matters in a Data Center Chiller

    Conventional compressor bearings are rolling or sliding contacts that need oil, and that oil has to be pumped, filtered, monitored and eventually replaced. In a refrigeration circuit, oil can also migrate into heat exchangers, where it can degrade heat transfer. Magnetic bearings remove the contact and the oil entirely: the shaft is levitated, sensors track its position thousands of times a second, and a digital controller adjusts the magnetic fields to keep it centred.

    SKF argues this reduces wear, maintenance and unplanned downtime, and that is the point that resonates with data center operators. Cooling is one of the few systems whose failure can force IT equipment to throttle or shut down, so operators design chiller plants with redundancy and treat maintenance windows carefully. Fewer wearing parts and no oil system mean fewer things that can fail and fewer reasons to take a unit offline.

    SKF positions itself as a full-stack supplier here: high-speed motors levitated on magnetic bearings, the bearings themselves, digital controllers, variable-speed drives (electronics that let the compressor run at whatever speed the cooling load requires), condition monitoring and engineering services. For a chiller maker, buying an integrated drivetrain can shorten its own development time; the trade-off is deeper dependence on a single supplier.

    Reading the 30–40% Efficiency Claim

    The release’s most quotable number is that SKF’s integrated magnetic-bearing offering delivers “energy efficiency improvements of up to 30–40% compared with conventional technologies.” Two qualifiers matter. “Up to” marks the top of a range, not a typical result. And the baseline, “conventional technologies,” is not defined: the gain from replacing an older fixed-speed, oil-lubricated compressor would be expected to be larger than the gain over a modern variable-speed unit.

    Efficiency at the chiller also does not translate one-for-one into data center energy savings. Chillers are one component of a cooling plant that includes pumps, cooling towers, air handlers and, in many climates, free-cooling modes that bypass the compressor for part of the year. The real-world benefit depends on the site’s climate, load profile and plant design.

    SKF’s broader framing, that around 20 percent of the world’s energy consumption goes to overcoming friction, is a company claim offered as context for its business rather than a specific figure for cooling. It is a reasonable reminder that rotating machinery is everywhere in infrastructure, but it should not be read as an estimate of savings available in data centers.

    Ceramics and Extreme Speeds Fill Out the Portfolio

    SKF is not betting only on magnetic levitation. It will also show hybrid ceramic bearings, including a new optimized CeraDrive series, for chillers, heat pumps, steam compressors, motors, fans and pumps. Ceramic rolling elements are electrically insulating, which matters in motors fed by variable-speed drives, where stray electrical currents can pass through and pit conventional steel bearings. SKF also says the ceramics support high-speed operation when lubrication conditions are demanding.

    The new Extreme super-precision platform targets high-speed centrifugal compressors in chillers, heat pumps and mechanical vapour recompression systems (which compress steam to reuse its heat). SKF quotes capabilities of up to 120,000 rpm, a speed factor of 2.4 million ndm (a bearing-industry measure combining diameter and rotation speed), ring contact pressure up to 2.8 GPa and turbine-side temperatures up to 200°C.

    Offering both magnetic and advanced rolling-element bearings lets SKF serve compressor designers whichever architecture they choose, from premium oil-free machines to cost-sensitive designs that still need high speed. Commercially, that hedges SKF against any single design winning out across the cooling market.

    Background

    SKF is a Gothenburg-based industrial group known primarily for bearings, the components that let shafts rotate smoothly in everything from cars to factory machinery. It describes its core business as reducing friction in rotating systems and claims that around 20 percent of the world’s energy consumption goes to overcoming friction. Beyond conventional bearings, SKF sells high-speed motors levitated on magnetic bearings, active magnetic bearings, digital controllers, variable-speed drives, condition monitoring and engineering services.

    Data center growth has turned cooling into a strategic concern for operators. SKF notes that as data center capacity expands, cooling places increasing demands on energy systems, pushing chiller and compressor makers to deliver more cooling capacity while limiting energy use, maintenance and complexity. Oil-free centrifugal compressors built on magnetic bearings are one way manufacturers have addressed that, and suppliers of their drivetrains, including SKF, are now competing on cost and production capacity as well as performance.

  • Munters Bets on Virginia to Shorten Data Center Cooling Lead Times

    Munters Bets on Virginia to Shorten Data Center Cooling Lead Times

    TL;DR · 30-second read

    The Short Version

    The machines that stop computer warehouses from overheating are hard to get right now. Munters, a Swedish company that makes that cooling equipment, has finished enlarging its factory in Daleville, Virginia.

    The site is now about the size of ten football fields and employs close to 600 people. It has started building chillers, the large refrigeration units that cool whole buildings. Until now those were shipped in from Italy.

    Why it matters: computers running artificial intelligence get very hot, and waiting for cooling gear is one reason new data centers open late.

    Munters said in a September 11 release distributed by PR Newswire that it has inaugurated an expanded campus for data center cooling in Daleville, Virginia, adding manufacturing, training and testing space. The site covers 565,000 square feet, employs close to 600 people, and is the largest of five dedicated manufacturing facilities inside the company’s Data Center Technologies business worldwide.

    The expansion lets Munters build every product in its data center cooling range at one address: air-side economizers, the patented SyCool Split, computer room air handling units, fan coil arrays, coolant distribution units, and now chillers, which were previously produced in Italy. The campus also houses the Munters Service Academy, new production test stands, and a chiller laboratory with an environmental chamber.

    Executive Summary

    The announcement is less about a building than about where a building sits. Munters has moved chiller assembly from Italy to a site a few hours’ drive from the densest concentration of data centers on earth, and it can now produce its entire cooling portfolio in one place rather than splitting production across continents.

    That matters because mechanical plant has become a gating item for artificial intelligence buildouts. A chiller is a large, heavy, custom-configured machine. Ocean freight, customs, currency swings and trans-Atlantic scheduling all sit between an order and a commissioned data hall, and none of them respond to urgency. Manufacturing on the same landmass as the customer removes weeks of that friction and makes change orders cheaper to absorb.

    The strategic logic is sound and the physical facts are specific. The performance claims attached to it are not. Munters describes its Circlemiser chiller as greatly reducing energy consumption and total required power versus typical air-cooled chillers, but publishes no percentage, baseline or test condition alongside that statement. Buyers should treat the factory as substantiated and the efficiency claim as a directional marketing position awaiting data.

    Geography Is the Product

    Daleville is in southwestern Virginia, near Roanoke and well outside the Northern Virginia cluster that hosts the world’s largest agglomeration of data centers. That distance is a feature. Land and labor are cheaper away from the cluster, while the finished equipment is still a domestic truck haul from the campuses that will consume it, rather than a port call.

    The freight economics of cooling equipment are unlike those of servers. A rack of compute is dense, valuable and air-freightable. A chiller is bulky, comparatively low in value per cubic meter, and moves by sea. Shifting Circlemiser production from Italy to Virginia therefore converts a multi-week international logistics chain into a domestic one, and removes a layer of tariff and currency exposure from the delivered price. For a developer whose revenue starts only when a hall is energized, schedule certainty on mechanical plant is worth real money.

    There is a second, quieter advantage. Cooling systems for large campuses are rarely catalog items. When engineering, manufacturing, testing and service training sit on one site, a design change can be resolved in a corridor conversation rather than across a seven-hour time difference. That compression of the iteration loop is the part of co-location that does not show up in a square-footage figure.

    One Roof, Air Through Liquid

    The portfolio list in the announcement is worth unpacking, because it maps the whole transition the industry is living through. Air-side economizers pull in outside air when it is cool enough, letting a facility idle its compressors and save power. Computer room air handling units, known as CRAHs, push chilled air through the room. Fan coil arrays do similar work closer to the equipment. These are the tools of the air-cooled era, and they still cool the overwhelming majority of installed capacity.

    Coolant distribution units, or CDUs, belong to the next era. They are the pump-and-heat-exchanger boxes that push liquid coolant directly to chips, which is how the densest artificial intelligence racks shed heat that air can no longer carry away fast enough. Chillers sit underneath both approaches, producing the chilled water that feeds air handlers and liquid loops alike.

    Building all of it in one factory is a hedge against an uncertain mix. No one knows precisely how quickly liquid cooling will displace air, or what share of a given campus will be hybrid. A manufacturer that can flex between the two without retooling a second site carries less risk than one that has bet a plant on a single architecture. The commercial question is whether that flexibility comes with the throughput a hyperscale order actually requires, and the announcement does not quantify capacity.

    Demand Is Evidently Not the Constraint

    Munters has told investors that order intake in the April-to-June quarter rose 137 percent, driven by strong demand in Data Center Technologies and its AirTech business, and separately announced an order worth roughly 2.0 billion Swedish kronor from a United States colocation provider for a modular artificial intelligence cooling solution. Capacity expansions generally follow backlog, and a backlog of that shape explains this one.

    The same quarterly communication was headlined around exceptional demand alongside external headwinds currently affecting profitability, which is the more instructive half of the picture. Order growth of that magnitude is expensive to serve. Ramping a new production line, qualifying a chiller laboratory, staffing test stands and training a service organization all consume cash before the first unit ships. Investors should expect the Daleville expansion to weigh on margins before it helps them, and should watch conversion of backlog into delivered revenue rather than intake alone.

    There is also a customer-concentration question embedded in any business growing this way. Large colocation and hyperscale orders are lumpy. A vendor that builds capacity against a small number of very large commitments is exposed if one of those programs slips, and artificial intelligence buildout schedules have proven willing to slip.

    The Scarce Input Is Trained People

    The presence of the Munters Service Academy on the expanded campus is a more revealing detail than the square footage. Frank Pellegrino, the incoming president of the business area, framed manufacturing setup as only part of the equation and pointed to skilled people, technical knowledge and service capability. That is an accurate description of where the sector’s real bottleneck has migrated.

    Liquid cooling changes the skills required in a data hall. Pumped coolant, quick-disconnect fittings and leak detection are not the same discipline as ducted air, and the installed base of technicians trained on the older approach is much larger than the base trained on the newer one. A vendor that trains its own service workforce, and its customers’ staff, controls a resource that cannot be bought with capital on a short timeline.

    For Botetourt County, close to 600 jobs in precision mechanical manufacturing is a meaningful anchor, and it places industrial employment in a part of Virginia that has not captured much of the data center boom’s direct benefit. Whether the expansion adds materially to that headcount is not stated. The figure given is the current workforce, not a hiring target.

    Background

    Munters is a Swedish climate-technology company, headquartered in Stockholm and publicly listed, that builds equipment for controlling temperature and humidity across industries. Its Data Center Technologies unit has grown into one of the sector’s more prominent specialist cooling suppliers as computing density has risen, and it operates five dedicated manufacturing facilities for that business globally. Daleville is the largest of them.

    Virginia has been the center of gravity for American data center development for more than two decades, with Northern Virginia hosting the largest concentration of capacity in the world. The artificial intelligence buildout has strained the supply chain that serves it. Chips draw attention, but the unglamorous mechanical inputs, chillers, air handlers, switchgear and transformers, have become the practical limit on how quickly capacity comes online. Placing manufacturing close to that demand is a response to the problem rather than a solution to it, and several equipment vendors have moved in the same direction.

  • Namecheap’s 15-Hour Outage Shows Why Denser AI Halls Can’t Rely on One Chiller Plant

    Namecheap’s 15-Hour Outage Shows Why Denser AI Halls Can’t Rely on One Chiller Plant

    TL;DR · 30-second read

    The Short Version

    A storm damaged the cooling system at a data center in Phoenix. A data center is a warehouse-sized building full of computers that must be kept cold to keep working. Without enough cooling, the web company Namecheap went dark for about 15 hours.

    Websites, email and even Namecheap’s own customer help line went offline. Fixing the cooling took hours. Getting everything else running again took much longer.

    This matters more as computers built for artificial intelligence, which run far hotter, fill new buildings. Backup cooling inside one building may not be enough.

    Namecheap, a leading domain registrar and web host, suffered an outage of roughly 15 hours on August 14 after what it called “a failure of cooling systems” at its data center in Phoenix. TechRadar reported that the company’s hosting plans, its EasyWP managed WordPress service, DNS (the internet’s address book, which points domain names at servers) and email were all offline, along with customer accounts and Namecheap’s own support desk. The facility’s operator, PhoenixNAP, said heavy overnight storms had caused damage that led to “elevated white space temperatures” in the data halls.

    Two of the data center’s four chillers were back online around 12pm EDT. Core databases returned at 5:30pm EDT, Namecheap.com and live chat about 40 minutes later, and full service at 3:50am EDT. Chief executive Hillan Klein apologised, saying “we failed you today,” and committed to publishing a post-mortem.

    Executive Summary

    A storm damaged the cooling plant of a Phoenix data center, and one of the best-known names in domain registration and small-business hosting went down for most of a day. Customers lost websites, email and name resolution. They also lost the usual way to get help, because Namecheap’s help desk and live chat went down with everything else.

    The incident matters beyond Namecheap’s customers because it isolates a failure mode the industry usually discusses in terms of power: the thermal plant. The building had four chillers, the industrial refrigeration units that produce the cold water used to pull heat out of server rooms. That redundancy did not prevent an outage when a single external event, a storm, affected the cooling system. Even after partial cooling returned, restoring the service stack took many more hours.

    That lesson gets sharper as operators pack far hotter AI hardware into new halls. When heat density rises, the time between losing cooling and losing servers shrinks. Resilience that stops at the building’s own chiller plant leaves less margin than it once did.

    Four Chillers, One Storm

    Data center cooling is normally designed with spare capacity. The common “N+1” approach means one more chiller than the load requires, so a single unit can fail or be serviced without consequence. Namecheap’s Phoenix facility had four chillers. Bringing two of them back online was the milestone that began recovery, which indicates the plant had been running well short of what the halls needed. Neither company had said, as of August 15, exactly how many units failed or which part of the cooling system the storm damaged.

    This is the core distinction between component redundancy and site resilience. Spare chillers protect against one machine breaking. They protect far less well against a common-mode event, meaning a single cause that hits several pieces of equipment at once. Storm damage to shared infrastructure is exactly that kind of event. PhoenixNAP’s own explanation traced the problem to weather rather than to an isolated equipment fault, so the redundancy on paper did not match the resilience in practice.

    Cooling Came Back Hours Before the Service Did

    The published timeline is the most instructive part of this incident. Partial chiller capacity returned around noon. Core databases did not come back until 5:30pm, and the public website and live chat returned about 40 minutes after that. Full service was not restored until 3:50am. Most of the outage therefore happened after the thermal problem had begun to ease.

    That gap reflects how hosting platforms behave after a thermal event. When a room overheats, servers throttle, shut themselves down, or are powered off by operators to protect the hardware. Bringing them back is not a single switch. Storage has to be verified, databases checked for consistency, and dependent services restarted in the right order. For anyone writing recovery objectives, the lesson is that restoring the cooling plant starts the recovery clock. It does not stop it.

    Why AI Halls Can’t Rely on One Chiller Plant

    Namecheap’s outage involved conventional web hosting, not AI hardware. The mechanism still applies directly to AI buildout. A room’s temperature rises after cooling fails at a rate set by how much heat the equipment keeps producing. Conventional hosting racks give operators some buffer. AI training and inference racks, built around dense GPU servers, concentrate far more heat in the same floor space, so the window for an orderly shutdown or failover gets shorter.

    Liquid cooling, now standard in many AI designs, moves heat off chips more efficiently than air. It still hands that heat to the facility’s central plant: chillers, dry coolers or cooling towers. A storm that damages that plant affects a liquid-cooled AI hall as surely as it affected Namecheap’s hosting floor, and the higher density leaves less time to react. The practical conclusion for operators and tenants is that resilience needs to extend beyond one plant. That can mean heat-rejection equipment that is physically separated and weather-hardened, or the ability to move workloads to another site. Buyers of AI capacity have reason to ask colocation providers how their cooling redundancy performs against shared causes, not only against a single failed unit.

    When the Help Desk Shares Fate With the Outage

    The outage also took down Namecheap’s support channels, leaving staff unable to answer live chat or email. The company fell back on its status page and on Klein’s posts on X. Namecheap did keep customers informed with detailed status updates throughout. The episode still shows why tools for talking to customers during a crisis are best hosted somewhere other than the infrastructure they report on.

    Klein’s commitment to examine “where our existing safeguards and protocols failed” is the right question. The test will be whether the post-mortem addresses architecture as well as the storm, specifically whether services like DNS and email had anywhere else to run when one building lost its cooling.

    Background

    Namecheap is one of the most widely used domain registrars, the companies that sell and manage website addresses. It also sells web hosting, managed WordPress through its EasyWP service, email and DNS, mostly to individuals and small businesses. Because many customers buy their domain, website and email from Namecheap together, one infrastructure failure can take down a business’s whole online presence at once.

    Data centers spend a large share of their engineering effort on cooling, because nearly all the electricity servers use becomes heat. Chilled-water plants are the workhorse of larger facilities and are normally built with spare units. Heat density per rack is rising sharply as AI hardware spreads, so the reliability of this thermal plant is becoming as central to uptime as power supply and backup generators.

  • Johnson Controls Q2 Sales Rise 8% on Data Center Cooling Demand

    Johnson Controls Q2 Sales Rise 8% on Data Center Cooling Demand

    Johnson Controls, one of the world’s largest building-technology and HVAC companies, reported an 8% year-over-year increase in sales for its fiscal second quarter, with data center cooling demand cited as a principal driver, according to a May 7, 2026 report by Facilities Dive. Because Johnson Controls’ fiscal year ends in September, its second quarter covers roughly January through March 2026.

    Executive Summary

    The headline number — 8% sales growth at a company of Johnson Controls’ scale — is notable less for its size than for its attribution. When a diversified industrial that sells everything from fire-suppression systems to building controls credits data center cooling as the engine of a quarter, it quantifies something the industry has sensed for two years: AI-driven data center construction has become a primary demand source for the industrial HVAC sector, not a niche vertical.

    Cooling is the second-largest consumer of power and capital in a data center after the IT equipment itself, because nearly every watt a server draws becomes heat that must be removed. As hyperscale operators — the companies running the largest cloud and AI facilities — race to add capacity, the vendors who make chillers, air handlers, and thermal-management systems are seeing that race show up directly in their revenue lines. Johnson Controls’ quarter is one of the cleaner public data points yet on how large that effect has become.

    From Building Controls to AI Infrastructure Supplier

    Johnson Controls has spent recent years narrowing its portfolio toward commercial buildings and applied HVAC — the large, engineered cooling systems used in campuses, hospitals, and data centers — including divesting its residential and light-commercial HVAC business to Bosch and acquiring Silent-Aire, a maker of modular cooling and hyperscale data center equipment, in 2021. A quarter in which data center cooling is called out as the growth driver suggests that repositioning is doing what it was designed to do: concentrate the company’s exposure where capital spending is heaviest.

    That matters for how investors and customers should read the company. Johnson Controls is increasingly priced and evaluated not as a building-products conglomerate but as a supplier to AI infrastructure buildouts — a category that commands different growth expectations, and different scrutiny, than traditional construction-linked HVAC.

    The Economics of the Cooling Boom

    Data center cooling is attractive business for industrial vendors for structural reasons. The equipment is large, engineered-to-order, and often sold with long-term service contracts — chillers (machines that produce chilled water to absorb heat from server halls) run continuously for decades and require ongoing maintenance. Hyperscale projects are also ordered in fleets rather than units, which fills factory backlogs years ahead and gives manufacturers unusual visibility and pricing power compared with the one-building-at-a-time commercial construction cycle.

    The industry is simultaneously navigating a technology transition. As AI chips grow denser, air cooling reaches physical limits, and liquid cooling — circulating coolant directly to the chips or their racks — is taking a growing share of new deployments. That transition is an opportunity for incumbents with liquid-capable portfolios and a risk for anyone whose installed strength is concentrated in legacy air-based systems. The source report does not break down how much of Johnson Controls’ growth came from which technology, a distinction that matters for judging how durable the growth is.

    A Rising Tide Across the Vendor Field

    Johnson Controls is not alone in reporting data-center-driven strength; the same demand wave has lifted results across thermal-management and power-equipment vendors, and competitors such as Vertiv, Carrier, Trane Technologies, Schneider Electric, Munters, and Daikin all compete for slices of the same buildouts. The significance of this quarter is corroborative: each vendor that attributes measurable growth to data centers adds evidence that hyperscale capital spending is flowing through to the industrial supply chain broadly, rather than pooling with one or two specialists.

    For data center operators and enterprises planning capacity, the flip side of vendor prosperity is procurement reality: strong vendor demand typically means longer lead times and firmer pricing for large cooling equipment. Buyers who plan orders early, standardize designs, and lock delivery slots hold the advantage in a seller’s market.

    The Concentration Question

    The risk embedded in an 8% quarter driven by one end market is the same as its appeal: concentration. Data center demand is ultimately a derivative of a handful of hyperscalers’ AI capital-expenditure decisions. If AI infrastructure spending decelerates — because of monetization pressure, power-availability constraints, or efficiency gains that reduce cooling intensity per unit of compute — the vendors that re-oriented toward this vertical would feel it quickly. Nothing in the source report suggests that is imminent, but a growth story built on one customer class deserves to be monitored as one.

    The even-handed reading: this quarter substantiates real, current demand flowing to a major HVAC vendor. It does not, by itself, establish how long the cycle runs, and the headline-level detail available leaves the durability question open.

    Background

    Johnson Controls traces its roots to 1885, when Warren S. Johnson commercialized the electric room thermostat, and grew over the following century into one of the world’s largest building-technology companies, spanning HVAC equipment (including the York chiller brand), building automation, and fire and security systems after its 2016 merger with Tyco. In recent years the company has deliberately narrowed toward commercial and engineered building systems, selling its residential and light-commercial HVAC business to Bosch and investing in data center capabilities, most visibly through the 2021 acquisition of hyperscale cooling specialist Silent-Aire.

    That repositioning coincided with the AI infrastructure boom, in which data center construction — and the power and cooling systems it requires — became one of the fastest-growing capital-spending categories in the global economy, reshaping demand for the entire industrial HVAC sector.
