Bromine Systems Inc.

Bromine Systems Inc., a for-profit small business manufacturer based in Addison, Illinois, supplies water treatment and chemical handling equipment to the Defense Department as a prime contractor on 98% of recent awards, competing predominantly under small business set-asides (Total Small Business and occasionally Service-Disabled Veteran-Owned Small Business designations) and full-and-open procurements. The company manufactures water demineralization cartridges, water testing equipment, chemical solution feeders, solenoid valves, feeder assemblies, and related components aligned to NAICS 333310 (Commercial and Service Industry Machinery Manufacturing) and PSC water purification equipment.

Bromine Systems has established itself as the dominant supplier of water treatment equipment to the Defense Logistics Agency, with 138 awards (97.2% of its award count by volume) concentrated in DLA Land and Maritime, generating $38.5 million in combined potential value. The remaining customer base includes DLA Troop Support Construction and Equipment (24 awards, $763 thousand), DLA Troop Support Medical (14 awards, $261 thousand), DLA Aviation (6 awards, $51 thousand), Department of the Navy Naval Sea Systems Command (5 awards, $14 thousand), Naval Supply Systems Command, and Military Sealift Command. DLA Land and Maritime accounts for approximately 97% of the company's combined potential value across all awards; the concentration is extreme and narrow. The top NAICS categories in the source data reflect the equipment mix: photographic and photocopying equipment manufacturing (43 awards), other commercial and service industry machinery manufacturing (40 awards), commercial and service industry machinery manufacturing (33 awards), and other measuring and controlling device manufacturing (16 awards). The top PSC is water purification equipment (119 awards).

Recent representative work illustrates the portfolio: a $220,912.50 Total Small Business set-aside purchase order from DLA Land and Maritime in March 2026 for 750 water demineralization cartridges (NSN 4610010229970) with June 2, 2026 completion; a $232,290 Total Small Business set-aside order from DLA Land and Maritime in January 2026 for the same cartridges with April 21, 2026 completion; a $30,121.20 open-competition purchase order from DLA Land and Maritime in January 2026 for a chemical solution feeder; a $220,912.50 Total Small Business set-aside from DLA Land and Maritime in July 2025 for 750 demineralization cartridges with January 5, 2026 completion; a $19,227.45 Total Small Business set-aside from DLA Medical Supply Chain in May 2025 for water testing equipment; and a $798,779.10 Total Small Business set-aside from DLA Land and Maritime in October 2021 for 3,290 water decontamination cartridges. The company also holds a $250,000 single-award indefinite delivery contract with DLA Land and Maritime for centrifugal pump units.

Activity has grown modestly year over year, from 10 awards in 2022 to 19 in 2024, with 17 awards in 2025 and 3 awards so far in 2026. The company holds three named indefinite delivery contracts: SPE7M218D0003 (23 task orders, $1.8 million combined potential value), SPE7MX15D5006 (16 task orders, $4.9 million combined potential value), and SPE7M120D60VN (1 task order, $242 thousand). Combined potential value across all 195 awards is $39.7 million, with $20.7 million obligated to date (52% realization).

Bromine Systems subcontracts to Marinette Marine Corporation on the FFG(X) Guided Missile Frigate detail design and construction, supplying bromine delivery systems, bromine cartridges, and potable water brominators under awards dated April 2022, December 2023, and December 2024. Subcontract work represents approximately 2% of recent award volume. The company has maintained federal contractor status since September 2014 and operates exclusively from its Addison, Illinois facility across all work. Set-aside posture is mixed: approximately 60% of recent awards carry Total Small Business or SDVOSB designations, with the remainder awarded on open-competition or no-set-aside basis.
