Danish Clean Water

What Danish Clean Water does

Danish Clean Water A/S (DCW), founded in 2008 and headquartered in Sønderborg, Denmark, designs and manufactures on-site electrochemical activation (ECA) generators used for water disinfection, biofilm removal, and Legionella control. The company operates with 11–50 employees and reports an installed base of more than 1,000 generators accumulated over 15+ years of operation.

The core technology uses membrane electrolysis to convert salt, water, and electricity into NEUTHOX — a stabilized hypochlorous acid (HOCl) solution marketed for both water and surface disinfection. The product portfolio comprises three generator families — LC (low-chloride, targeted at closed-loop systems), STD (standard industrial), and Mini — sold alongside salt tablets and NEUTHOX liquid under a recurring replenishment model. Disclosed unit economics include a generator ASP of approximately DKK 105,000 (~USD 15,000) and annual salt consumables of approximately DKK 14,000 (~USD 2,000) per installation, supplemented by biannual service contracts.

DCW serves more than eight end markets, including healthcare (hospitals, care homes), hospitality (hotels), residential housing associations, agriculture (pig and poultry farms), and industrial segments (manufacturing, food processing, breweries, and shipping/oil & gas). Customer evidence includes named deployments at Danfoss, KAB housing, a UK hospital, an airport hotel, a Northern Ireland poultry farm, a Danish wastewater plant, Skovhave pig farm, Diamanten sports centre, and Dybbøl care home. Distribution combines direct enterprise sales with a direct-to-customer webshop (neuthox.dk) for smaller accounts and consumables. Regulatory positioning is anchored in ECHA Article 95 listing, UK DWI Regulation 31, ISO 9001 certification, and a reference in UK HSG274 Part 2 water-safety guidance, with prior participation (2020–2023) in a national Danish Legionella project alongside Statens Serum Institut and the Danish Technological Institute.

Revenue model

1. Disinfection Generators: DCW manufactures and sells disinfection generator units based on ECA technology. Generators are sold as capital equipment to businesses and public institutions. Two product lines: Low Chloride (LC) generators and Standard (STD) generators, available in multiple sizes for different industry applications. One case study references generator costs of DKK 105,000 for a residential installation, with payback achieved within 4 years through energy savings.
2. NEUTHOX Disinfectant Consumables: NEUTHOX disinfectant solution is consumed continuously as it is dosed into water systems. Users refill salt tablets periodically and purchase NEUTHOX liquid for surface disinfection. The generator produces NEUTHOX on-site from salt, water, and electricity, creating an ongoing consumables revenue stream from salt tablets and periodic liquid disinfectant refills. One source notes that salt costs approximately DKK 14,000 per year for a wastewater treatment facility.
3. Service and Maintenance: DCW recommends a service every six months for changing filters and calibrating the sensor. This creates a recurring service revenue stream from annual maintenance contracts for enterprise customers.

Core offering

Danish Clean Water manufactures and sells ECA (Electrochemical Activation) disinfection generators and the NEUTHOX disinfectant liquid. The generators produce NEUTHOX (hypochlorous acid) on-site from water, salt, and electricity to kill Legionella and other bacteria, destroy biofilm, and prevent bacterial re-occurrence in water systems. The company serves hospitals, care homes, hotels, sports venues, housing associations, industrial facilities, and agricultural operations.

Product overview

Danish Clean Water offers a portfolio of disinfection products consisting of ECA (electrochemical activation) generators and the NEUTHOX disinfectant liquid. The generators (including Low Chloride, Standard, and Mini models) produce NEUTHOX on-site through electrolysis of water and salt, requiring only common salt and electricity. NEUTHOX contains hypochlorous acid (HOCl) as its active ingredient and is used to eliminate Legionella, bacteria, and biofilm from water systems and surfaces without toxic chemicals. The systems are fully automated, require minimal maintenance, and comply with European regulations.
