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.
