Davey UV57 Steriflo 110 L/Min UV Water Treatment System

Environmental demands in medium-sized residential water loops often involve microbial risks from untreated rainwater, boreholes, or municipal supplies, which the UV57 R Series addresses through high-intensity ultraviolet irradiation. This system is specified for point-of-entry applications where waterborne pathogens require neutralization without chemical intervention. The reactor supports versatile orientation, allowing for vertical or horizontal mounting to accommodate specific plant room or pump shed configurations. It maintains the original taste and mineral profile of the liquid while providing a continuous microbiological barrier.

The reactor vessel is constructed from 304 Stainless Steel using A249 pressure-rated tubing to maintain structural integrity. It houses a high-purity quartz sleeve that protects the internal lamp while allowing maximum UV-C transmission. With a shipping weight of 6.5 kg, the unit is manageable for various mounting scenarios. Operation is rated for water temperatures between 2 and 40 degrees Celsius. The internal chamber diameter is 64 mm with a total length of 1016 mm.

This system operates on a 90-265V 50/60Hz supply with a total power consumption of 62 W. The internal ultraviolet lamp is rated at 50 W and the unit operates with a maximum current of 1 Amps. It achieves a peak flow rate of 57 L/Min at a 30mJ/cm2 dosage and up to 110 L/Min at 16mJ/cm2. Connections consist of 25 mm MNPT inlet and outlet ports. The system is designed for a maximum operating pressure of 860 kPa and a minimum of 69 kPa.

Electrical components are protected within a splash-proof case featuring a fully potted ballast. An integrated lamp change reminder provides maintenance alerts, while a lamp out indicator allows for status checks. The unit utilizes high-intensity low-pressure high-output lamp technology. Mounting brackets are included for installation. The controller measures 172 x 92 x 102 mm. Maintenance is performed through a tool-free design that allows for lamp changes with a quarter-turn. The system is designed to provide consistent performance over the life of the lamp.
