    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.

    Monitored Residual

    Automated dosing can maintain a measured ClO2 residual; organism and biofilm control depend on product and system conditions.

    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 and free chlorine have different oxidation chemistry; treatment performance depends on dose, contact time and water conditions.

    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 has a different by-product profile from free chlorine: it forms no chloramines and generally very little THM or HAA, while chlorite and chlorate require control.

    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 used for control of Legionella pneumophila, Pseudomonas aeruginosa, E. coli and biofilm within their product-type compliance, with efficacy supported by standard laboratory testing and documented case studies. Our regenerative chlorine dioxide technology penetrates biofilm matrices, and laboratory testing to EN standards has shown greater than log 6 microbial reduction under the test conditions at low residual concentrations. Read more about biofilm formation and control.

    Chlorine dioxide (ClO2) is an oxidising biocide used across a wide pH range. It can act on biofilm, forms no chloramines and generally very little THM or HAA, while chlorite and chlorate require control through dosing and measurement. Product efficacy depends on the target organism and validated conditions. It is not a reliable Cryptosporidium barrier, where UV or filtration is required. 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) where the product's stated use and conditions apply. Product testing reported greater than log 6 reduction of Legionella pneumophila under its specified conditions. Chlorine dioxide can act on biofilm, while site performance requires monitoring and corrective action. 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 used for drinking-water treatment and forms no chloramines and generally very little THM or HAA. Its inorganic by-products, chlorite and chlorate, must be controlled by dosing and measurement within applicable limits.

    Chlorine dioxide forms no chloramines and generally very little THM or HAA, but chlorite, chlorate and other by-products require control. Pool and spa suitability depends on the specific product label and monitoring programme. Chlorine dioxide also retains activity over a wider pH range than free chlorine.
