About the company
Mecs, Inc. Elessent Clean Technologies Division, a subsidiary of DuPont De Nemours, Inc. based in St. Louis, Missouri, manufactures specialized industrial filtration and separation equipment—mist eliminators, hydrogen demisters, filter assemblies, and gaskets—for the U.S. Department of Defense as a prime contractor (97% of recent awards) under full-and-open competition with no recurring small-business set-aides, though one Troop Support purchase order carried a Total Small Business designation. The division operates under primary NAICS 333998 (All Other Miscellaneous General Purpose Machinery Manufacturing) and PSC 3655 (Centrifugals, Separators, and Pressure and Vacuum Filters), delivering firm fixed-price purchase orders to naval and defense logistics customers.
Customer concentration is heavily skewed to naval operations. The Department of the Navy Naval Supply Systems Command dominates both volume and dollars, accounting for 48 awards with $10.2 million in combined potential value—62% of the division's recent award count and 75% of combined potential value across its entire portfolio. The second-largest customer, Navy Naval Sea Systems Command, holds 15 awards valued at $2.4 million. Defense Logistics Agency Land and Maritime follows with 7 awards at $454 thousand, Military Sealift Command with 3 awards at $235 thousand, and Naval Air Systems Command Naval Air Warfare Center with 2 awards at $175 thousand. These five customers account for 96% of awards and 99% of combined potential value—a concentration profile characteristic of a single-platform supplier. Recent prime work includes a $678.4 thousand mist eliminator from Naval Supply Systems Command (May 2025), a $547.6 thousand SEPA filter assembly from Naval Supply Systems Command (May 2023), a $462.4 thousand mist eliminator from Naval Supply Systems Command (August 2023), and a $400 thousand gasket purchase from DLA Land and Maritime (July 2023).
Activity has remained modest but steady—three awards in 2022, climbing to seven in 2025 and two in 2026 to date. Only one award (potential value $62 thousand) faces ultimate completion within the next twenty-four months, presenting minimal near-term recompete exposure. The division also holds two subcontract positions: a mist-eliminator sub to Huntington Ingalls Inc. on a CVN 75 aircraft-carrier refueling and complex overhaul advance planning contract (July 2025) and a demister sub to Kato Engineering Inc. on CVN 81 EMALS full-production work (April 2025). The division's combined obligated dollars ($14.7 million across 78 recent awards) exceed combined potential value by 8%, indicating routine contract modifications and invoicing above original ceiling values on firm fixed-price equipment purchases.
