About the company

Avantech, LLC, a for-profit limited liability company and manufacturer of goods headquartered in Columbia, South Carolina, manufactures specialized water treatment equipment and nuclear support systems for the U.S. Navy as a prime contractor (80% of recent awards) and as a subcontractor to defense and Department of Energy primes. The vendor operates in full-and-open competition — no set-asides appear across its prime footprint — and is registered in SAM.gov since 2002.

Avantech's core capability is demineralizer manufacturing and related water treatment equipment for naval nuclear propulsion programs. The vendor's primary NAICS classification is Other Commercial and Service Industry Machinery Manufacturing (20 awards), followed by Hazardous Waste Treatment and Disposal (10 awards), and the PSC profile is dominated by Water Purification Equipment (57 awards). Representative prime work includes a $2.667 million definitive contract from Naval Sea Systems Command awarded March 13, 2025, for a 7-cubic-foot demineralizer with HIC/overpack for completion by May 1, 2030; a $190,783.68 purchase order from NAVSEA awarded September 30, 2021, for demineralizers supporting Navy nuclear propulsion; and a $29,750 purchase order from NAVSEA awarded April 7, 2026, for a 7-cubic-foot shielded demineralizer unit, firm fixed price, with completion by July 10, 2026.

Customer concentration is acute. The Department of the Navy Naval Sea Systems Command accounts for 54 of 61 prime awards and $7.3 million combined potential value, with the balance split among the Department of Energy Office of Environmental Management (14 awards, dollars not specified in source), the Department of the Navy Pacific Fleet Forces (2 awards, $113 thousand), and minor Air Force procurement (2 awards, $103 thousand combined). Avantech holds a seat on an indefinite delivery contract (IDC 89303324DEM000096) under which it has placed 7 task orders.

Activity in the past five years shows concentrated recent growth: two awards in 2022, two in 2023, ten in 2024, six in 2025, and one in 2026. The combined potential value across all 61 prime awards is $7.5 million, but obligated dollars total $75.5 million — reflecting multiple task orders and modifications flowing through repeat vehicles and supplier relationships. As a subcontractor, Avantech delivers equipment fabrication and environmental monitoring systems to Hanford Tank Waste Operations & Closure, LLC (5 sub awards in FY2024–FY2025 for ion exchange resin column fabrication, thermal oxidation system units, and radioactive particulate monitoring cabinets) and to Fluor Marine Propulsion, LLC (1 sub award in FY2024 for pool filtration mechanical skids supporting the Naval Nuclear Laboratory). The vendor also subcontracts to prime contractors supporting the Waste Isolation Pilot Plant's transuranic waste program and has supported Department of Energy and Department of Defense operations through sub-award work on environmental remediation and waste handling systems. SCI-reported service-contract activity shows minimal engagement: two named-subcontractor records in FY2022–FY2024 representing nominal FTE delivery (1.0 FTEs in FY2022, 0.0 in FY2024), indicating that Avantech's federal revenue is driven predominantly by goods manufacturing rather than service contracting.
