NEUTRALOX Umwelttechnik GmbH

What NEUTRALOX Umwelttechnik GmbH does

NEUTRALOX Umwelttechnik GmbH is a German manufacturer of photoionisation (PI) units for exhaust air purification and odour elimination, headquartered in Berlin with production in Hennef (Rhein-Sieg-Kreis). Founded in 1998 and now part of KF Unternehmensgruppe (acquired 2024), the company designs modular, scalable, plug-and-play systems that combine UV light with a downstream catalyst to oxidise H₂S, mercaptans, ammonia, VOCs, and other odour compounds. The product line covers Small (500–1,500 m³/h), Medium (2,000–5,000 m³/h), and Large (10,000+ m³/h, including the NX15000 model) configurations, with ATEX Zone 2 and CSA/UL Class 1/Div. 2 certified variants for hazardous environments and validated operation from -40°C to desert conditions. In March 2025, NEUTRALOX merged with uviblox GmbH, consolidating two odour-elimination specialists under the KF Group umbrella.

The company sells turnkey PI systems and complementary KatOx catalytic add-on modules to municipal and industrial wastewater treatment plants, sewage pumping stations, food processing facilities (cheese, sausage, spices, flavourings, roasting), and pharmaceutical/cosmetics manufacturers. Revenue is generated through hardware sales (project-based, quote-priced) plus a recurring after-sales services stream covering maintenance contracts, TCP/IP-based remote monitoring, spare parts (UV lamps, activated carbon filters, KatOx systems), retrofit consulting, and service work for other manufacturers' systems. Go-to-market is sales-led enterprise field sales, supported by the channel partner NEUTRATEK Odour Solutions for the Americas, a Chicago subsidiary (Neutralox Inc., est. 2015) for North American after-sales, and an active trade-show presence at IFAT Munich, WEFTEC Chicago, Aquatech Mexico, and Pollutec Lyon.

Customer evidence is concentrated in municipal/government WWTPs across six continents (named cases in Australia, USA, Canada, Germany, South America, and India), with 500+ plants installed worldwide and quantified outcomes including >99.8% H₂S reduction at Missoula (Montana), 135,000 GE/m³ → <500 GE/m³ at the Australian municipal WWTP, and claimed 60% energy savings versus conventional systems. The company's competitive position rests on its 25-year proprietary PI technology platform, regulatory certifications for explosive atmospheres, and an installed base that supports recurring service revenue and retrofit opportunities.
