Treat the water / Disrupt the biofilm / Control the complete system
Legio-Oxy® is a powdered, three-component catalytic oxidation formulation developed for professional remediation of Legionella-contaminated water systems.
Legio-Oxy® combines an oxygen-releasing component, a heterogeneous titanium-based catalyst and a surface activator. After preparing a concentrated solution, the formulation is dosed into the circulating system to generate hydrogen peroxide and reactive oxygen species intended to damage Legionella cells and associated biofilm. Treatment must form part of a complete water-safety programme that includes risk assessment, temperature and flow management, cleaning, flushing, validated sampling and long-term verification. A one-time chemical treatment cannot replace continuous system control.
Rapid oxidative remediation / Long-term water-system management
Professional Legionella control across engineered water systems
Legio-Oxy® should only be used by trained personnel within applications covered by its current registration, approved label and site-specific risk assessment.
Hotels & Tourist Accommodation
Remediation support for complex hot- and cold-water systems serving guest rooms, showers and communal facilities.
Hospitals & Care Facilities
Professional treatment of high-risk water systems under infection-control and water-safety supervision.
Schools, Colleges & Kindergartens
Treatment support following stagnation, shutdown, contamination or failure of routine water-management controls.
Apartments, Offices & Shopping Centres
Applicable to large building-water systems containing storage tanks, circulation loops and low-use outlets.
Cooling Towers & Evaporative Systems
Potential use in aerosol-generating cooling systems where specifically authorised and integrated into a formal control programme.
Public & Government Buildings
Supports controlled system remediation before reopening or after confirmed Legionella contamination.
Four complementary functions / For controlled Legionella remediation
Hydrogen-Peroxide Generation (OXY-RELEASE)
The oxygen-source component releases hydrogen peroxide after preparation in water, providing the basis for oxidative treatment.
Heterogeneous Titanium Catalyst (CATALYTIC-ACTIVATION)
The Titansorb-based catalyst is intended to accelerate peroxide decomposition and reactive oxygen-species formation.
Biofilm Wetting and Penetration (SURFACE-CONTACT)
A surface-active component improves contact between the treatment solution, system surfaces and accessible biofilm.
Circulating Oxidative Treatment (SYSTEM-REMEDIATION)
Controlled circulation distributes the treatment through accessible parts of the water system before flushing and verification.
Science & Technology
Legio-Oxy® is designed to combine peroxide chemistry, catalytic activation and surface contact to inactivate susceptible microorganisms and disrupt accessible biofilm.
- Hydrogen-Peroxide Release – Prepared solution releases hydrogen peroxide ($H_2O_2$), an oxidizer that damages proteins, membranes and microbial structures.
- Catalytic Decomposition – A heterogeneous catalyst promotes peroxide decomposition and reactive oxygen-species formation (pathway depends on catalyst, pH and water composition).
- Microbial Inactivation – Oxidative damage reduces viable Legionella cells by disrupting cellular components and enzyme systems (efficacy depends on concentration, contact time and temperature).
- Biofilm Treatment – Legionella persists within biofilms and amoebae; effective remediation requires cleaning, hydraulic access and sufficient disinfectant exposure throughout the system.
