    Protection

    Auto Dose System

    Automated Chlorine Dioxide Dosing, Around the Clock

    Our auto dose system continuously monitors water conditions and delivers precise, measured doses of chlorine dioxide directly into the water circuit. It removes the reliance on manual testing and dosing, ensuring consistent protection 24 hours a day.

    Continuous Protection

    Maintains a consistent ClO2 residual that controls Legionella, Pseudomonas, E. coli and biofilm 24/7, not just at the point of manual dosing.

    Less Staff Time

    Replaces manual testing rounds with automated monitoring and dosing, freeing maintenance teams while improving consistency.

    Compliance Confidence

    Provides an auditable trail of dosing activity and water quality readings, supporting ACOP L8, HSG274 and HSG282 requirements.

    Scales Effortlessly

    From a handful of units to 200+ hot tubs, the system scales without requiring proportional increases in staff.

    Source: figures above (99.99% bacterial reduction, 99% chemical reduction, £401k annual saving) are verified results from ChloroKlean UK case studies. Chlorine dioxide is a stronger oxidising biocide than chlorine (WHO drinking water guidance) and remains effective across pH 4-10.

    Did You Know?

    Chlorine dioxide is 2.6x more powerful than chlorine as an oxidizing agent, making it far more effective at lower concentrations.

    Chemistry

    Biofilms can harbour up to 1,000 times more bacteria than free-floating cells, making them a hidden threat in water systems.

    Microbiology

    Legionella bacteria can survive for up to 12 months in stagnant water, which is why regular treatment is essential.

    Public Health

    Unlike chlorine, chlorine dioxide remains effective across a pH range of 4-10, making it versatile for various applications.

    Chemistry

    A single cooling tower can release millions of water droplets per minute, potentially spreading Legionella up to 6km away.

    HSE Research

    Chlorine dioxide doesn't form harmful trihalomethanes (THMs), making it safer for drinking water treatment.

    Frequently Asked Questions

    ChloroKlean is a UK-based principal stockist of BPR-compliant industrial disinfection products using chlorine dioxide and sodium hypochlorite. We offer biocidal products across six GB BPR product types: PT2 (pools, spas, public areas), PT3 (veterinary hygiene), PT4 (food contact surfaces), PT5 (drinking water treatment), PT11 (cooling systems), and PT12 (slimicides). Our flagship product is ChloroKlean Plus L20 with regenerative chlorine dioxide technology.

    Yes, ChloroKlean products are proven effective against Legionella pneumophila, Pseudomonas aeruginosa, E. coli, biofilms, and other waterborne pathogens. Our regenerative chlorine dioxide technology penetrates biofilm matrices and achieves greater than log 6 microbial reduction at less than 0.5ppm free chlorine. Read more about biofilm formation and control.

    Chlorine dioxide (ClO2) is a powerful oxidizing biocide with 2.6x more oxidizing power than chlorine. Unlike chlorine, it works effectively across a wide pH range (4-10), penetrates and destroys biofilms, produces no harmful disinfection by-products (THMs, HAAs), and doesn't form chloramines. It's also effective against chlorine-resistant organisms like Cryptosporidium. Learn more in our technical comparison article.

    ChloroKlean products are supplied for the Great Britain market in compliance with GB BPR (the retained version of EU Regulation 528/2012), for the specific product types stated on each label. EU BPR, which applies in the EU and Northern Ireland, is a separate regime and we do not claim EU or NI authorisation. Our manufacturing is certified to ISO 9001:2015, Halal, and Kosher standards. Distribution is certified to ISO 9001, ISO 14001, ISO 27001, and ISO 45001.

    ChloroKlean products are available in sizes from 500ml to 1000L IBC. Smaller sizes (500ml, 1L, 5L) qualify for LQ (Limited Quantity) shipping. Larger sizes (10L, 25L, IBC 1000L) require full ADR shipping arrangements.

    ChloroKlean products are used across multiple industries including healthcare (hospitals, care homes), food processing (meat, dairy, produce washing), water treatment (cooling towers, potable water), hospitality (hotels, spas, swimming pools), agriculture (veterinary facilities, livestock), and industrial applications (paper manufacturing, biogas). Each sector has specific product recommendations based on their compliance requirements.

    ChloroKlean products support compliance with HSE ACOP L8 (Legionnaires' disease: The control of legionella bacteria in water systems) by providing effective Legionella control in hot and cold water systems, cooling towers, and evaporative condensers. Our products achieve greater than log 6 reduction of Legionella pneumophila and penetrate biofilm where Legionella bacteria harbour. See our hospital Legionella case study.

    Regenerative chlorine dioxide technology refers to ChloroKlean Plus L20's unique formulation that generates chlorine dioxide in situ through a controlled reaction. Unlike tablet or two-part generation systems, this technology provides consistent ClO2 concentration, longer residual protection, and eliminates the need for on-site mixing or specialised dosing equipment. Learn more on our technology page.

    Yes, ChloroKlean PT5 products are specifically formulated for drinking water disinfection and comply with GB BPR regulations for potable water treatment. Chlorine dioxide is widely used for drinking water treatment worldwide due to its superior disinfection efficacy, minimal taste and odour impact, and absence of trihalomethane and chloramine by-products (its inorganic by-products, chlorite and chlorate, are controlled by dosing within regulatory limits).

    Chlorine dioxide does not form harmful disinfection by-products (DBPs) like trihalomethanes (THMs) or haloacetic acids (HAAs) that traditional chlorine produces when reacting with organic matter. ClO2 also does not form chloramines with ammonia, making it safer for swimming pools and spa applications. Additionally, chlorine dioxide remains effective at higher pH levels where chlorine loses efficacy. Read our detailed comparison article.

    ChloroKlean (spelled with a capital K, one word, no spaces) is a UK brand of BPR-compliant industrial disinfection products manufactured by Spa Trade Group Ltd, London. ChloroKlean specialises in chlorine dioxide products for water treatment, Legionella control, food processing, and swimming pool disinfection. The flagship product is ChloroKlean Plus L20 with regenerative chlorine dioxide technology.
