About Linde Inc.

Linde Inc., Linde Gases United States Division, doing business as Praxair, supplies industrial gases—aviator's breathing oxygen, liquid nitrogen, liquid oxygen, liquid hydrogen, helium, propellant pressurization services, and related cryogenic products—to federal agencies as a prime contractor across more than $1.23 billion in combined potential value across 2,670 recent awards, operating predominantly in the full-and-open market with no SBA set-aside designations.

Linde is a foreign-owned, for-profit manufacturer of industrial gases headquartered in Danbury, Connecticut, with primary NAICS 325120 (Industrial Gas Manufacturing) and PSC 6830 (Gases, Compressed and Liquefied). The company operates through multiple subsidiaries including Praxair, Inc., Tafa Incorporated, Nuco2 Inc., and Compressed Gas Services, Inc. Linde competes exclusively in unrestricted, full-and-open procurements; across the award portfolio, 98% are prime awards and 2% are sub-awards, with all primary work executed from its Danbury, Connecticut facility.

Customer concentration is heavily weighted toward the Defense Logistics Agency Energy, which dominates by award count with 1,411 awards and $262.8 million in combined potential value, followed at distance by the Department of the Air Force (126 awards), Department of the Army (71 awards, $1.1 million), NASA Glenn Research Center (52 awards, $3 million), and Department of the Navy Naval Sea Systems Command (48 awards, $53 thousand). By potential value, however, NASA Kennedy Space Center anchors the portfolio with 40 awards and $601.5 million, followed by DLA Energy's $262.8 million. This divergence reflects Linde's high-volume, low-value delivery-order pattern with DLA Energy (which places frequent routine replenishment orders for breathing oxygen and propellant pressurization) versus large, long-duration supply contracts with NASA for helium and cryogenic gas delivery through 2029 and 2030.

Linde holds five named parent indefinite delivery vehicles: an October 2025 NASA Agency-wide Supply of Liquid and Gaseous Helium 2025-2030 contract (41.4 million ceiling, multiple award, 13 NASA facilities); a September 2025 Department of Defense single-award IDV for aerospace gases and pressurization ($3.9 million ceiling, September 2025–June 2030); a September 2024 Defense Logistics Agency single-award IDV for propellant pressurization ($582 thousand ceiling, expiring September 2025); a July 2024 NASA Agency-wide Acquisition of Nitrogen and Oxygen 4 (NANO 4) multiple-award IDIQ for liquid nitrogen and liquid oxygen across Glenn, JPL, Johnson, and Kennedy Space Centers ($43.9 million ceiling, through June 2029); and an October 2023 NASA indefinite delivery contract for gaseous and liquid helium across 23 delivery sites ($5 million ceiling, October 2023–September 2025). These vehicles enable efficient task-order placement; the top five parent vehicles show 159 to 83 task orders each, with cumulative values in the hundreds of thousands to tens of millions. Recent award activity is flat to slightly declining—59 awards in 2022, declining to 19 through April 2026—with only 2 awards facing completion within the next twenty-four months and combined recompete exposure of $933 thousand.

As a subcontractor, Linde supplies bulk gases, tank rental, nitrogen gas service, and industrial gas infrastructure to prime contractors including Lockheed Martin Corporation (JASSM nitrogen gas tank rental, M-TADS/PNVS system gas service, LRASM nitrogen gas tank rental), Honeywell Federal Manufacturing & Technologies (National Security Campus bulk gas and tank services under contract DE-NA0002839), and Beyond New Horizons, LLC (Test Operations and Sustainment II monthly tank rental for argon and liquid nitrogen). Linde also serves as a sub-recipient on federal grants awarded to Purdue University, University of Utah, Washington University, and University of Missouri System for hydrogen production, carbon capture, oxy-combustion power plant development, and sustainable aviation fuels, where Linde provides engineering support, design reviews, and testing consultation.

Linde is a prime recipient on two federal grants from the Department of Energy: a January 2025 cooperative agreement with the Office of Energy Efficiency and Renewable Energy for demonstration of a heavy-duty hydrogen refueling station connected to commercial-scale hydrogen pipelines in the Gulf Coast region (ultimate completion October 2025), and an October 2021 cooperative agreement with the Office of Fossil Energy for engineering study of Svante's solid sorbent post-combustion CO2 capture technology at a Linde steam methane reforming hydrogen plant (completed November 2023).

Linde's federal work centers on supply of specialty industrial gases and pressurization services to defense, aerospace, and energy sectors. Concrete examples include a $16.1 million July 2024 Kennedy Space Center delivery order for liquid nitrogen and liquid oxygen through June 2029 under NANO 4; a $5.3 million October 2025 delivery order to NASA Goddard Space Center for gaseous and liquid helium to the Columbia Scientific Balloon Facility through September 2030; a $10.7 million March 2023 Kennedy Space Center delivery order for liquid hydrogen (extended through November 2025); a $900 thousand August 2025 Army Corps of Engineers Wolf Creek Dam liquid oxygen supply purchase order (4,000 tons base, through December 2026); and recurring monthly delivery orders from DLA Energy for aviator's breathing oxygen and propellant pressurization ranging from $1 thousand to $224 thousand per order. The company has maintained federal contracting relationships continuously since December 2001, establishing it as a stable, long-tenured supplier of mission-critical cryogenic and industrial gas products to government space, defense, and research operations.
