Southwest Gases Opens Argon Capacity to Texas Chip and Data Center Customers

Flower Mound distributor is taking new argon and bulk liquid argon accounts as Texas fabs and data centers add load
Southwest Gases is taking new argon and bulk liquid argon accounts in Texas, including from semiconductor and data center customers, the distributor said this week. It kept its order book open through last spring’s helium allocations, when one large U.S. supplier capped some buyers at half their normal monthly volume. It says it is holding the same position on argon.
Argon does most of its work in a fab at the deposition step. It is the process gas in physical vapor deposition, where a plasma knocks metal atoms off a target so they land on the wafer, and the gas has to be ultra-high purity or the film picks up what the gas brought with it. Argon also supplies the atmosphere for annealing, when wafers are heated to repair crystal damage and switch on their dopants, and it blankets the furnace while a silicon ingot is pulled. The list of plants that can make argon to electronics grade is short.
Data centers use it for something else. Argon is one of the inert agents recognized under NFPA 2001, on its own as IG-01 or blended with nitrogen, and it protects the electrical and telecom rooms where a water discharge would do more damage than a small fire. It leaves no residue, carries no current, and has a global warming potential of zero. That last point counts for more every year, as quotas tighten on the chemical agents it competes with.
What catches buyers out is that argon supply has very little to do with argon demand. Argon is 0.93% of the air, and it comes off the same distillation column as oxygen, with under three degrees between their boiling points. Those plants get built and sized for oxygen and nitrogen customers, most of them steel mills. When steel runs slow, the host plant turns down and the argon side-stream shrinks with it. One major producer raised North American liquid argon prices by as much as 20% and gave continued low operating rates in the steel market as the reason. Nothing had happened to argon itself.
“Argon is the one that surprises people,” said Rudy De La Fuente of Southwest Gases. “Customers assume that if they need more, somebody will make more. Nobody makes argon on purpose. It shows up because a steel mill wanted oxygen, and if that mill drops a shift, your argon gets harder to find three months later. We carry stock against that instead of hoping.”
The demand side in Texas is not in question. The state has at least 13 existing or announced semiconductor fabs and more than 51,500 people working in the industry, and has been the top U.S. exporter of semiconductors and electronic components for 14 consecutive years, according to the Office of the Governor. Samsung has committed more than $40 billion to a chipmaking hub in Central Texas. Texas Instruments’ Sherman site has room for up to four fabs and the potential to reach $40 billion in capital investment.
Data center construction has moved on a similar curve. CBRE put Dallas-Fort Worth inventory past 1,400 megawatts in the first half of 2026, with more than 765 megawatts under construction and 95% of that pre-leased before it opens. Vacancy sat at 2.8%.
Southwest Gases delivers argon in cylinders and as bulk liquid from Flower Mound, with high-purity grades for laboratory and electronics work and welding grades for fabrication. Liquid argon travels economically for a couple of hundred miles, a cylinder for about fifty. The last leg of the chain belongs to regional distributors for that reason, and a plant recovers under 40% of the argon that arrives with the air, so what sits in a distributor’s yard is most of what a buyer can get at short notice.
