What Aqua-Chem does

Aqua-Chem, Inc. is a Knoxville, Tennessee-based designer, manufacturer, and servicer of industrial water purification systems founded in 1929 and operating today as the North American platform of Nijhuis Saur Industries (NSI), the Industrial Water division of French group Saur, following its May 2022 acquisition. The company's product portfolio spans thermal and membrane-based technologies, including its proprietary Horizontal Spray-Film Vapor Compression distillation systems (300-9,000 gph capacity), the second-generation TORRENT Ambient WFI/PW membrane system, beverage and military-grade reverse osmosis units, pure steam generators, carbon towers, UV/ozone disinfection, and complete engineered "water room" solutions integrating pretreatment through storage and distribution. Its core technology — the Spray-Film Vapor Compression process developed in 1960 — remains an industry benchmark for Water-for-Injection production and is supplemented by LG Chem NanoH2O thin-film nanocomposite membranes.

The company serves four primary verticals: pharmaceutical/biotech (Pfizer, Selkirk Pharma, a 20+ year major pharma customer relationship with one of the world's largest WFI installations), beverage manufacturers, oil & gas (offshore platforms), and the U.S. military (equipment on 263 of 276 Navy ships, plus Tactical Water Purification Systems and ROWPUs). Secondary markets include commercial marine and industrial wastewater. Revenue is generated through capital equipment sales (one-time), aftermarket parts and consumable membrane replacement (recurring hardware), and service/maintenance programs including the Aqua-Care Service offering preventative maintenance, commissioning, operator training, and 24/7 technical support.

Aqua-Chem sells through a direct enterprise field sales force in North America complemented by regional sales offices and a global distributor network across South America, Europe, Africa, Asia, and the Pacific. Approximately 70% of revenue comes from North America. The company holds extensive regulatory certifications (ISO 9001, ASME U/S/R stamps, ASME BPE, PED, NSF 61, CE, ABS, DNV) that constitute significant barriers to entry in pharmaceutical-grade water systems. Headcount has grown from 165 employees at the time of the Saur acquisition to 250+ currently, reflecting post-acquisition expansion.
