OCS-COOL GUARD Legionella Biosafety
Permanently control Legionella risk in your cooling tower with continuous ozone dosing. Your legal obligation is documented with an automatic monthly report.
The Problem
Periodic Shock Dosing Isn't Enough
Cooling towers offer an ideal breeding ground for Legionella pneumophila. Between chlorine shock treatments bacteria regrow, and biofilm shelters in spots chlorine can't reach.
Intermittent Protection
Bacterial colonies regrow between periodic shock treatments.
Biofilm Resistance
Chlorine can't penetrate the biofilm layer well enough; Legionella stays protected.
Lack of Documentation
Systematic, continuous monitoring data for audits is usually missing.
Corrosion Risk
High-concentration chlorine causes corrosion in system components.
System Concept
Protect Continuously, Document Automatically
OCS-COOL GUARD works with a four-component architecture.
Continuous Dosing
24/7 low-dose ozone injection prevents biofilm formation at the source.
Biofilm Penetration
Ozone penetrates existing biofilm and destroys the colonies inside it.
Continuous Monitoring
Ozone concentration, pH and temperature are measured continuously.
Automatic Reporting
The system produces an automatic monthly Legionella risk report — audit-ready.

FAQ
Frequently Asked Questions
No — applied at the correct dose, ozone doesn't harm equipment. On the contrary, it reduces corrosion risk compared to chlorine chemicals.
Ozone concentration history, pH and temperature data, alarm logs and a Legionella risk-assessment summary.
In most cases yes, but in some applications low-dose chlorine can be kept alongside ozone. This is determined in the site assessment.
Thanks to its modular design, multiple towers can be managed from a central system — ideal for industrial zones and large complexes.
