Euroacque EURO/LOTUS AIR/10/B automatic chlorine dioxide generator 10 g/h for water disinfection

Euroacque EURO/LOTUS AIR/10/B – Automatic Chlorine Dioxide Generator 10 g/h for Water Disinfection and Legionella Prevention

The Euroacque EURO/LOTUS AIR/10/B is an automatic chlorine dioxide (ClO₂) generator designed for professional disinfection of potable water and water systems. It autonomously produces, doses and controls chlorine dioxide, one of the most effective disinfectants available for the prevention of Legionella pneumophila, disinfection of water distribution networks and biofilm control. Made in Italy by Euroacque, manufacturer since 1978.

Key Technical Data

• ClO₂ production: 10 g/h
• Solution concentration: 2 g/l
• Maximum chemical consumption: HCl 9% → 0.192 l/h; NaClO₂ 7.5% → 0.156 l/h
• Raw materials: Hydrochloric Acid (HCl 9%) + Sodium Chlorite (NaClO₂ 7.5%)
• Operating pressure: ambient pressure (no internal pressure)

Operating Principle

Chlorine dioxide is produced through the controlled reaction between dilute hydrochloric acid (HCl 9%) and dilute sodium chlorite (NaClO₂ 7.5%) inside a dedicated reaction chamber. The process operates in batch mode: the produced solution is stored in an internal tank and dosed into the water flow proportionally to the volumetric flow rate measured by the connected pulse output meter. Proportional dosing ensures a constant and precise ClO₂ concentration in the water system, regardless of flow rate variations.

Key Technical Features

• Batch process at ambient pressure – maximum operational safety: no internal pressure, eliminating risks associated with pressurised chlorine dioxide
• Dedicated reaction chamber – the reaction between reagents takes place in a confined and controlled space, ensuring optimum yield and safety
• Activated carbon filter – protects the surrounding environment from any ClO₂ emissions, ensuring personnel safety and compliance with environmental regulations
• Multifunction safety valve – ensures control and safety of all phases of the generation and dosing process
• Dosing proportional to volumetric flow rate – the system integrates with a Euroacque pulse output meter to modulate dosing in real time based on actual consumption
• Internal storage tank – the produced solution is stored and dosed on demand, optimising reagent consumption

Main Applications

• Legionella prevention in water systems of hotels, hospitals, healthcare facilities, apartment buildings and industries
• Disinfection of potable water distribution networks
• Control and removal of biofilm in pipework
• Water treatment for cooling towers
• Disinfection in food processing plants

Important Notes

Dosing systems to prevent Legionella are part of a good risk reduction strategy but do not alone, and without maintenance, guarantee complete resolution of the problem. An integrated Legionella risk management programme is required.

Must be used with a pulse output flow meter (Euroacque CONTO series) for flow-proportional dosing.
