Neutralox Umwelttechnik GmbH

Neutralox Umwelttechnik GmbH, part of the KF Unternehmensgruppe family of companies, develops and manufactures photoionisation-based odour control systems for municipal and industrial wastewater treatment facilities. Headquartered in Hennef, Germany, the company has deployed over 500 installations worldwide and draws on more than 25 years of operating experience in exhaust air purification. Neutralox's core technology, branded as NEUTRALOX Photoionisation, combines ultraviolet irradiation with a downstream catalytic stage to destroy odorous compounds in exhaust air streams. The company reports purification efficiencies exceeding 99 percent and energy savings of 60 percent or more compared with conventional odour control methods such as chemical scrubbing or activated carbon adsorption. Systems are built on a modular, scalable, plug-and-play architecture, allowing capacity adjustments across a range of facility sizes without extensive re-engineering. Primary applications include odour treatment at sewage treatment plants, forced ventilation of sewer networks and pumping stations, and exhaust air purification in the food processing and pharmaceutical industries. Neutralox also provides aftersales service covering maintenance, spare parts, and system optimisation. As a member of the KF Unternehmensgruppe, which employs over 400 people across multiple environmental technology businesses, Neutralox benefits from shared engineering resources and an established international sales and service network.
