AS and AL Series
Water Disinfection Systems
WRAS-approved the AS and AL Series of UV water disinfection systems are high-performing and efficient UV systems designed to disinfect flow rates ranging from approximately 33 to 365 m³/hr, typical in commercial and industrial installations.
The AS and AL series incorporate amalgam technology for long lamp life and consistent performance. These are particularly practical in environments that are subject to temperature fluctuations where performance and energy efficiencies are valued.
All Daro UV chambers are designed and manufactured at our plant in the United Kingdom. Systems in the AS and AL Series are manufactured to the highest levels of precision for excellent performance, are made from 316 stainless steel and carry a 10-year chamber warranty as standard. All parts can be recycled, giving the series the benefit of a low carbon footprint.
Each chamber has an integrated thermal drain and UV intensity monitor as standard to ensure units run smoothly and ensure the appropriate UV dose is delivered for effective and reliable disinfection in industrial applications.
