A factory is running when its owner says it is. A chiller has shipped when a customer receives one. Modine's November 11 release reports the first. It does not report the second.
Modine, a Wisconsin maker of cooling equipment, said it has begun commercial production of Airedale chillers at a new plant in Grand Prairie, Texas. One line and one shift are running. The release lists four lines and three shifts as goals. Kalkine and The Inference covered the start that day. This piece adds the dates around it and the gaps. Where a number is our own arithmetic, we say so.
What does Modine's Texas plant make, and why does it matter?
The plant makes air-cooled chillers for data centers. A chiller cools the water that carries heat out of a data hall.
A data hall cannot run at full load without that cooling. According to Modine's release, the units are rated 2MW and 3MW and use free cooling. Free cooling means using cold outside air to do part of the work when the weather allows. Target customers are hyperscale cloud providers, colocation operators and high-density AI computing environments. Airedale also sells coolant distribution units (CDUs), which move liquid coolant to hot equipment. Chillers are the only product the release ties to Grand Prairie.
Cooling gear has to be built, delivered and accepted before a project can use it. That makes this plant one link between a data center announcement and a running data hall. The release says nothing about customer sites.
What did Modine report, and what did it leave out?
It reported a production start and a set of targets. It left out the figures that would show how much the plant has built.
| In the November 11 release | Not in the release |
|---|---|
| Commercial production began in November at a 682,000-square-foot plant | What the plant cost |
| First line running, one shift | How many chillers it has built |
| Target of four 2MW lines by the end of the fiscal year, subject to equipment commissioning, workforce readiness and other operational considerations | Shipments or named customers |
| Plan to move from one shift to three | Customer acceptance |
| Expected to become the largest Airedale chiller plant Modine has | Headcount or the total number of lines planned |
The release also lists Modine's own risks, including customer or construction delays, supply chain and tariff issues and community opposition to data centers. Those are standard warnings, and they describe the chain this plant sits in.
How long did the plant take to start?
The first line started about 15 months after the plan was announced and later than the earliest dates made public. The record does not show why.
Modine announced a $100 million expansion on July 29, 2025, to be spent over 12 to 18 months, including a new facility in the Dallas area. That release gave no line counts. In October 2025 a city release put the plant at 2100 Refuge Way and expected groundbreaking in the fourth quarter of 2025 and operations in the first quarter of 2026. It projected more than 1,000 jobs. Later that month BizTimes reported that the site was "scheduled to open early next fiscal year" with five chiller lines.

Modine's fiscal 2027 began April 1, 2026. The first line started in its fiscal third quarter. That is later than "early next fiscal year" and later than "operations" in the first quarter of 2026.
The words differ, though. The city said "operations" and Modine now says "commercial production." The release does not say when the building opened or when the first equipment arrived. A staged opening is normal, and a building can open months before a line sells product. So this is not a documented delay. It is a first line that started later than the earliest public dates, with no company explanation either way.
The five-line figure is the other loose end. It came from a trade report of an earnings call and does not appear in Modine's releases. The November release sets a target of four 2MW lines by fiscal year-end and gives no total. The two can both be true if five is the eventual plan.

What has to happen next, and how fast?
Three more lines have to start in about 20 weeks if Modine meets its own target.
Modine's fiscal year ends March 31 (its latest results release calls March 31, 2026 the end of fiscal 2026), so "the end of the current fiscal year" reads as March 31, 2027. Our arithmetic: that is 140 days after November 11.
The first line took about 15 months from the plan announcement, and the release makes the next three subject to commissioning and workforce readiness.
The money side is visible in Modine's November 3 results for the quarter ended September 30. Data Centers sales were $439.7 million, up 95% from $225.0 million. The segment's adjusted EBITDA margin was 15.4%. Chief executive Neil Brinker cited "record orders and backlog" in that segment. A plant ramp is how a backlog turns into deliveries.
Building capacity costs cash. Capital spending for the six months was $88.5 million against $59.4 million a year earlier, and the release ties the increase to production capacity for Data Centers. Free cash flow was a use of $145.6 million. Net debt was $573.7 million, up $210.9 million from March 31. These are company-wide numbers and do not isolate this plant.
Four steps from factory to data hall
A cooling plant has four checkpoints: the building opens, a line runs, a unit ships and a customer accepts it. The release shows the second for one line. Nothing public shows the third or the fourth.
That is not a warning sign. A first line is supposed to be a start, and the release says so. The open question is pace: whether lines two through four start on schedule and whether finished units leave the plant on dated orders. Customer acceptance is what unlocks money in other deals, as in WhiteFiber's $300 million loan. Here it is the last step in the chain.
What would show a Modine chiller reached a customer?
A statement or filing that a second line is running would show the ramp moving. A shipment to a named customer would show the first unit reached the market.
Modine said it will share longer-term revenue and earnings targets at its Analyst and Investor Day on November 18. Nothing public says that event will cover this plant, so treat it as a possible update only. The cleaner test is the fiscal year-end target of four lines.
A factory opening tells you what a company intends. A dated shipment and a customer's sign-off tell you what happened. We will update this record when Modine reports either.
Next milestone
A Modine release or filing showing a second line running or units shipped to a named customer. The company's target is four 2MW lines by the end of its fiscal year, which reads as March 31, 2027.
The wait for cooling and power also shapes why AI data centers wait years for power, and the cooling side of the chain shows up in the HVAC company behind LG's 5GW cooling deal.
